As shown in Figure 1, a BRAS connects hosts over IPoE connections, and provides AAA, security, DHCP, and portal services for the hosts. The host can be a browser running HTTP or HTTPS or a cellphone running the H3C iNode client.

Figure 1 IPoE network diagram

IPoE access modes

IPoE supports Layer 2 and Layer 3 access modes.

· Layer 2 access mode—Hosts directly access the BRAS. The hosts connect to the BRAS directly or through Layer 2 devices. The BRAS uses MAC addresses to identify the hosts.

· Layer 3 access mode—Hosts use routing to access the BRAS. The hosts connect to the BRAS directly or through Layer 3 devices. On a Layer 3 device between the hosts and BRAS, the source MAC address of packets received by the BRAS is the MAC address of the Layer 3 device. Therefore, the BRAS uses IP addresses or VLAN IDs to identify hosts.

IPoE user types

IPoE sessions can be initiated by IP, ARP, NS, NA, ND RS, or DHCP packets. Depending on whether an IPoE user has independent service attributes, IPoE users include individual users and leased users.

Individual users

Individual users use independent IPoE services. The BRAS authenticates, authorizes, and accounts individual users based on user location and packet information. Individual users include dynamic and static individual users.

· Dynamic individual users

IPoE defines the following dynamic individual users:

? DHCP user—Sends DHCP packets to initiate IPoE sessions and obtains an IP address from the DHCP server.

? IPv6 ND RS user—Sends IPv6 ND RS packets to initiate IPoE sessions and obtains an IP address from the BRAS.

? Unclassified-IP user—Sends packets other than DHCP and IPv6 ND RS packets to initiate IPoE sessions.

· Static individual users

Static individual users initiate IPoE sessions by sending IP, ARP, NS, or NA packets. If an IP packet matches a manually configured IPoE session, the BRAS authenticates the user and establishes an IPoE session.

NOTE:

A DHCP user is abnormally logged out if the IPoE session of the user is deleted for a reason except the user actively releases its IP address. With the function of allowing abnormally logged out DHCP users to come online again enabled, when the device receives IP or ARP packets from the user, the device can restore the IPoE session for the user. The restored IPoE session is a DHCP session. For more information about re-logging in abnormally logged out DHCP users, see "Allowing abnormally logged out DHCP users to come online again through packet initiation."

Leased users

Leased users include the following types:

· Interface-leased user—Represents hosts that rent the same interface.

· Subnet-leased user—Represents hosts that rent a subnet of an interface.

· L2VPN-leased user—Represents hosts that rent the same interface on an L2VPN network.

The BRAS automatically uses the credentials configured for a leased user to perform authentication. Users are not required to send IP packets to trigger authentication.

IPoE session

An IPoE session represents all network connections of one IPoE client or a group of IPoE clients. An IPoE session can be identified by the IP packet characteristics or access location of clients. An IPoE session records the identification information, authentication status, authorization attributes, and DHCP address assignment information of IPoE clients.

Depending on the IPoE user types, IPoE sessions include individual sessions and leased sessions. .

Individual sessions

Depending on how a session is initiated, IPoE individual sessions include IPoE dynamic individual sessions and IPoE static individual sessions.

· IPoE dynamic individual session

IPoE sessions established for dynamic individual users are IPoE dynamic individual sessions.

The BRAS deletes a dynamic individual session in one of the following cases:

? The AAA-authorized session duration expires.

? The AAA server logs out the user.

? The user traffic is less than the AAA-authorized traffic during the idle-timeout time.

? The BRAS cannot detect the user after the number of detection attempts reaches the maximum.

- For a single-stack user, the session is deleted when the number of detection attempts reaches the maximum.

- For a dual-stack user, the session is deleted when the number of detection attempts reaches the maximum for both stacks.

? The IP address lease expires for IPoE sessions initiated by DHCP packets.

- For a single-stack user, the session is deleted when the IP address lease expires.

- For a dual-stack user, the session is deleted when the IP address leases of both stacks expire.

? The IPoE session is restarted.

? The access interface goes down.

· IPoE static individual session

An IPoE static individual session represents all network connections of an IPoE client with the specified IP address. Typically, IPoE static individual sessions provide stable access services for clients with known IP addresses.

IPoE static individual sessions include interface-level static individual sessions and global static individual sessions.

? Interface-level static individual sessions—The BRAS creates a static individual session based on configured information after you enable IPoE on an interface in up state. The BRAS initiates user authentication based on the configured username and password upon receiving IP, ARP, NS, or NA packets from users.

? Global static individual sessions—On an IPoE-enabled interface in up state, the BRAS initiates authentication based on the configured username and password upon receiving IP, ARP, NS, or NA packets from users. The BRAS creates a global static individual session only when the authentication succeeds.

IPoE leased sessions

IPoE leased sessions are IPoE sessions established for IPoE leased users. IPoE leased sessions include the following types:

· Interface-leased session—Represents network connections of all IPoE clients on an interface.

· Subnet-leased session—Represents network connections of all IPoE clients in a subnet of an interface.

· L2VPN-leased session—Represents network connections of all IPoE client on an interface.

For leased users, the BRAS creates a leased session based on configured information after you enable IPoE on an interface in up state. The BRAS initiates user authentication based on the configured username and password.

IPoE addressing

IPoE addressing varies with user types.

A DHCP user obtains IP addresses in the following sequence:

1. Obtains an IP address from the AAA-authorized IP address pool.

2. Obtains an IP address from the IP address pool configured in the ISP domain if the AAA server does not authorize any IP address pools.

3. Obtains an IP address in the same network segment as the interface IP address if no IP address pool is configured in the ISP domain.

After an IPv6 ND RS user passes authentication, the user can obtain an IPv6 prefix and generate an IPv6 address based on the prefix. IPv6 prefixes include the following types in descending order of priority: AAA-authorized IPv6 prefix, prefix in the AAA-authorized ND prefix pool, RA prefix configured on an interface, and IPv6 global unicast address prefix configured on an interface.

When an ND prefix pool is used to assign prefixes to users, follow these restrictions and guidelines:

· This methodis unavailable in .

· On a user access interface, you must configure a link-local address rather than an IPv6 global unicast address as the user gateway.

Other users use static IP addresses or obtain IP addresses from the DHCP server without using IPoE.

IPoE access procedure by using bind authentication

IPoE access by using bind authentication includes the following steps:

1. The BRAS initiates authentication.

The BRAS obtains information from user packets or IPoE sessions statically configured, and sends authentication requests.

2. The AAA server authenticates users.

The AAA server completes user authentication and sends the result to the BRAS. The security server, if configured, completes security authorization and sends the result to the BRAS.

3. (Optional.) DHCP allocates IP addresses and IPoE allocates IPv6 prefixes.

The DHCP server assigns an IP address to a DHCP user and the IPoE assigns an IPv6 prefix to an IPv6 ND RS user.

4. The BRAS performs access control.

The BRAS permits the user to get online and performs access control and accounting based on the authorized result.

Access procedure for DHCP single-stack users

This section uses a DHCPv4 user as an example to illustrate the access procedure for DHCP single-stack users. The BRAS acts as a DHCP relay agent.

Figure 2 Access procedure for a DHCPv4 user

1. The DHCPv4 client sends a DHCP-DISCOVER message.

2. The DHCPv4 relay agent inserts Option 82 in the DHCP-DISCOVER message, and creates an IPoE session.

3. The relay agent sends the AAA server an access request including user information, such as the client ID and source MAC address in DHCPv4 packets.

4. The AAA server returns an Access-Accept packet that contains authorization information to the DHCPv4 relay agent if the authentication succeeds. If the authentication fails, the AAA server returns an Access-Reject message.

5. The DHCPv4 relay agent obtains the user authentication and authorization result, and updates the session status to success or failure.

6. The DHCPv4 relay agent forwards the DHCP-DISCOVER message to the DHCP server if the authentication succeeds. If the authentication fails, the DHCPv4 relay agent drops the DHCP-DISCOVER message.

Access procedure for IPv6 ND RS users

This example uses a Layer 2 device as the BRAS.

Figure 4 Access procedure for IPv6 ND RS users

1. The host sends an IPv6 ND RS packet to the BRAS.

2. The BRAS initiates an IPoE session and sends the AAA server an access request that contains user information, such as the source MAC address.

3. The AAA server returns an Access-Accept packet that contains authorization information to the BRAS if the authentication succeeds. If the authentication fails, the AAA server returns an Access-Reject message.

6. The host generates an IPv6 address based on the received IPv6 prefix.

7. The BRAS sends the AAA server a message to start the service accounting.

Access procedure for unclassified-IP users

Figure 5 Access procedure for unclassified-IP users

1. The host sends an IP packet to the BRAS.

2. The BRAS obtains user information from the IP packet, and compares the user information with existing IPoE sessions.

? If no match is found, the BRAS initiates an IPoE session for the user. (This section uses this case as an example.)

? If the information matches an authenticated session, the BRAS forwards the IP packet.

? If the information matches an unauthenticated session, the BRAS drops the IP packet.

3. The BRAS sends the AAA server an access request containing the obtained information, such as the source IP address or source MAC address.

4. The AAA server returns an Access-Accept packet that contains authorization information if the authentication succeeds. If the authentication fails, the AAA server returns an Access-Reject message.

5. The BRAS assigns a user profile and marks the IPoE session state as online.

6. The BRAS sends the AAA server a message to start the service accounting.

Access procedure for static and leased users

The access procedure for static users is the same as that for unclassified-IP users except in the following aspects:

· The IPoE static session is configured at the CLI.

· The IPoE static session can be initiated by IP, ARP, NS, or NA packets.

The access procedure for leased users is the same as that for unclassified-IP users except in the following aspects:

· The IPoE leased session is configured at the CLI.

· The IPoE leased session does not need to be initiated by packets. Users are not required to send IP packets to trigger authentication. The BRAS initiates user authentication based on the configured username and password.

IPoE access procedure by using Web authentication

IPoE Web authentication applies to DHCP users, IPv6 ND RS users, and static users. The authentication process includes two phases: preauthentication and Web authentication.

Preauthentication access procedure

The access procedure in the preauthentication phase is the same as the access procedure by using bind authentication for DHCP users and static users. For more information about the access procedure, see "Access procedure for DHCP single-stack users," "Access procedure for IPv6 ND RS users," and "Access procedure for static and leased users."

Web authentication access procedure

In the Web authentication phase, the authentication procedure is almost the same for users. This section uses a DHCPv4 user as an example to illustrate the access procedure by using Web authentication. The BRAS acts as a DHCP relay agent.

Figure 6 Web authentication access procedure

The user can perform Web authentication through the Web browser or the iNode client. This section uses the Web browser as an example.

1. The DHCP client initiates an HTTP/HTTPS GET message.

2. The BRAS checks the destination IP address of the HTTP/HTTPS GET message.

? If the message is destined for the portal Web server, the BRAS forwards the message to the portal Web server. The DHCP client directly accesses the Web authentication page of the portal Web server. .

? If the message is not destined for the portal Web server, the BRAS sends the message containing the Web server URL information to the DHCP client.

3. The DHCP client automatically accesses the redirected URL based on configured Web server URL information.

4. The portal Web server sends the Web authentication page to the DHCP client.

5. The user enters a username and password on the Web authentication page.

6. The portal server forwards the Web authentication information to the BRAS.

7. The BRAS sends the AAA server an access request based on the Web authentication information.

8. The AAA server returns to the BRAS one of the following results:

? An Access-Accept packet that contains authorization information if the authentication succeeds.

? An Access-Reject message if the authentication fails.

9. The BRAS performs one of the following operations based on the received result:

? Updates the IPoE session state as failed upon receiving an Access-Reject message.

? Updates the IPoE session state as authorized upon receiving an Access-Accept packet.

10. If the authentication succeeds, the BRAS sends the AAA server a message to start accounting.

NOTE:

When the user performs Web authentication through the iNode client, the user can directly open the client authentication page and enter the authentication information. The remaining steps 6 through 10 are the same.

IPoE quick Web authentication

In an IPoE Web environment, IPoE Web authentication supports quick authentication. With quick authentication, users that access the network frequently do not need to enter authentication information each time they come online in the Web authentication phase.

For valid users that access the network frequently, you can implement MAC-based quick authentication. It allows users to pass authentication without entering authentication information. MAC-based quick authentication is also called transparent authentication. Based on the location where the usernames, passwords, and MAC-to-account bindings of users are stored, transparent authentication includes the following types:

· Transparent MAC-trigger authentication—To use transparent MAC-trigger authentication, you must deploy a MAC binding server in the network. The MAC binding server records the MAC-to-account bindings of users for authentication.

· Transparent MAC authentication—To use transparent MAC authentication, you must deploy an AAA server that can bind the Web authentication information of users to MAC addresses of user endpoints for authentication.

With IPoE quick Web authentication configured, IPoE queries the MAC bindings for a user when receiving any IP packets of the user in the preauthentication domain. For a user that uses Web access for the first time, the authentication procedure includes the querying process.

Transparent MAC-trigger authentication procedure

IMPORTANT:

· Transparent MAC-trigger authentication is only supported by IPv4 users.

· Transparent MAC-trigger authentication supports only Web authentication that is triggered through the Web browser.

1. The client initiates HTTP/HTTP requests after coming online in the preauthentication domain.

2. The BRAS checks the destination IP of the HTTP/HTTPS request.

3. If the message is destined for the portal Web server, the BRAS forwards the message to the portal Web server.

4. If the message is not destined for the portal Web server, the BRAS sends a binding query request to the portal server. The portal server returns the query result.

If the query result shows that the user has not been bound, the following operations are performed:

a. The BRAS redirects the subsequent HTTP/HTTPS requests to the Web authentication page of portal Web server. The BRAS sends HTTP/HTTPS messages containing the Web authentication page URL of the portal Web server to the client.

b. The client browser automatically accesses the Web authentication page of the portal Web server.

c. The portal Web server sends the Web authentication page contents to the client.

d. The user enters the username and password and click Log in to send the authentication information to the portal server.

If the query result shows that the user has been bound, the BRAS waits for the Web authentication information from the portal server.

5. The portal Web server sends the Web authentication information to the BRAS.

6. The BRAS sends the AAA server an access request based on the Web authentication information.

7. The AAA server returns to the BRAS one of the following results:

? An Access-Accept packet that contains the authorization information if the authentication succeeds.

? An Access-Reject message if the authentication fails.

8. The BRAS performs one of the following operations based on the received result:

? Updates the IPoE session state as failed upon receiving an Access-Reject message.

? Updates the IPoE session state as authorized upon receiving an Access-Accept packet.

9. If the authentication succeeds, the BRAS sends the AAA server a message to start accounting.

10. (Applicable only to users that perform Web authentication the first time.) After the user comes online, the BRAS notifies the portal server of the event. After receiving the notification, the portal server notifies the MAC binding server to add a MAC binding for the user.

When the user accesses the network the next time, the user can come online through quick authentication based on the queried MAC binding entry after the BRAS receives any IP packets of the user.

Transparent MAC authentication procedure

IMPORTANT:

· Transparent MAC authentication supports only Web authentication that is triggered through the Web browser.

The transparent MAC authentication procedure is as follows (take the first login as an example):

1. The client initiates HTTP/HTTP requests after coming online in the preauthentication domain.

2. The BRAS checks the destination IP of the HTTP/HTTPS request.

3. If the message is destined for the portal Web server, the BRAS forwards the message to the portal Web server.

4. If the message is not destined for the portal Web server, the BRAS uses the MAC address of the user as the username to send authentication requests to the AAA server. Because the user logs in for the first time, the AAA server fails to query the binding of the user based on the MAC address and returns authentication failure.

a. The BRAS redirects the subsequent HTTP/HTTPS requests to the Web authentication page of portal Web server.

b. The client browser automatically accesses the Web authentication page of the portal Web server.

c. The portal Web server sends the Web authentication page contents to the client.

d. The user enters the username and password and click Log in to send the authentication information to the portal server.

5. The portal Web server sends the Web authentication information to the BRAS.

6. The BRAS sends the AAA server an access request based on the Web authentication information.

7. The authentication succeeds. The AAA server returns to the BRAS an Access-Accept packet that contains the authorization information.

8. The BRAS updates the IPoE session state as authorized upon receiving an Access-Accept packet.

9. The authentication succeeds. The BRAS sends the AAA server a message to start accounting.

10. After the user comes online, the BRAS notifies the AAA server of the event. After receiving the notification, the AAA server adds a MAC binding for the user.

When the user accesses the network the next time, the BRAS uses the MAC address of the user as the username to send authentication requests to the AAA server after receiving any IP packets of the user. The AAA server can query the MAC binding for the user and returns authentication success. Then, the user can come online without entering the username and password.

Support for MPLS L3VPN

IPoE supports MPLS L3VPN. It uses AAA to authorize VPNs for users. Before you bind a VPN instance to an interface, you must delete existing IPoE sessions on the interface for the users to communicate in their authorized VPNs.

NOTE:

· When an unclassified IPoE user comes online through an authorized VPN, you must configure a gateway IP address or use the gateway-list export-route command to advertise the gateway IP address in the DHCP address pool of the public network on the access interface. As a best practice, advertise the gateway IP address in the DHCP address pool of the public network. For more information about the gateway-list export-route command, see DHCP commands in BRAS Services Command Reference.

· When a non-unclassified IPoE user comes online through an authorized VPN, you must configure a gateway IP address or enable proxy ARP by using the proxy-arp enable command on the access interface. As a best practice, enable proxy ARP. For more information, see proxy ARP configuration in Layer 3—IP Services Configuration Guide.

· Leased users do not support AAA-authorized VPNs through ISP domains or AAA servers. For more information about VPN authorization through ISP domains, see "Configuring AAA."

Support for ITA

ITA provides accounting and bandwidth solutions for users based on the destination addresses they access.

For more information about configuring ITA, see "Configuring AAA."

Support for EDSG

EDSG identifies the traffic of different services for a user and provides independent authentication, accounting, and rate limit for the traffic of each service.

After a user passes RADIUS authentication, the RADIUS server assigns EDSG service policies to the user. Then, the device uses the matching local EDSG service policies to provide service-based differentiated functions for the user.

For more information about configuring EDSG, see "Configuring EDSG service policies."

Support for EAP authentication

To use IPoE authentication that supports Extensible Authentication Protocol (EAP), make sure the portal authentication server and client are the H3C IMC portal server and the H3C iNode portal client, respectively.

Compared with username and password based authentication, digital certificate-based authentication provides higher security.

EAP supports several digital certificate-based authentication methods, for example, EAP-TLS. Working together with EAP, IPoE authentication can implement digital certificate-based user authentication.

Figure 7 IPoE support for EAP working flow

As shown in Figure 7, the authentication client and the portal authentication server exchange EAP authentication packets. The portal authentication server and the access device exchange portal authentication packets that carry the EAP-Message attributes. The access device and the RADIUS server exchange RADIUS packets that carry the EAP-Message attributes. The RADIUS server that supports the EAP server function processes the EAP packets encapsulated in the EAP-Message attributes, and provides the EAP authentication result.

The access device does not process but only transports EAP-Message attributes between the portal authentication server and the RADIUS server. The access device requires no additional configuration to support EAP authentication.

Restrictions and guidelines: IPoE configuration

For IPoE configuration to take effect on an interface, make sure the qos apply user-profile command has not been executed on the interface. For more information about the qos apply user-profile command, see user profiles commands in BRAS Services Command Reference.

This feature is available only when the system operates in standard mode. For more information about the system operating modes, see device management in Fundamentals Configuration Guide.

Only SPEX/CSPEX (except CSPEX-1104-E)/CEPC cards support IPoE.

IPoE and IP source guard are mutually exclusive. For more information about IP source guard, see Security Configuration Guide.

IPoE supports the following interfaces:

· Layer 3 aggregate interfaces/subinterfaces.

· Layer 3 Ethernet interfaces/subinterface s.

· L3VE interfaces/subinterfaces.

In an IPv6 network, an endpoint might use a temporary IPv6 address for IPoE Web authentication, which will cause authentication failure. To avoid this problem, configure the ipv6 nd ra prefix { ipv6-prefix prefix-length | ipv6-prefix/prefix-length } no-advertise command on the interface through which the user comes online to prevent the endpoint from obtaining a temporary IPv6 address. The ipv6-prefix prefix-length | ipv6-prefix/prefix-length argument specifies the IPv6 prefix and prefix length of the network segment where the user resides. For information about temporary IPv6 addresses, see IPv6 basics in Layer 3—IP Services Configuration Guide.

When the device acts as the DHCP server that assigns IP addresses to IPoE users, you must execute the following commands:

· For a DHCPv4 address pool, execute the dhcp server forbidden-ip command or the forbidden-ip command to exclude the gateway IP address from dynamic allocation.

· For a DHCPv6 address pool, execute the ipv6 dhcp server forbidden-address command to exclude the gateway IPv6 address from dynamic allocation.

For more information, see DHCP commands and DHCPv6 commands in BRAS Services Command Reference.

If both the ISP domain and DHCP server are configured to assign the DNS servers to IPoE DHCP users, the following rules apply:

· If the IPoE device acts as a DHCP server, the DHCP users preferentially use the DNS servers assigned by the ISP domain.

· If the IPoE device acts as a DHCP relay agent, the DHCP users preferentially use the DNS servers assigned by the DHCP server.

In a DHCP relay agent network, the following rules apply:

· When IPoE operates in Layer 3 access mode and the BRAS acts as a DHCP server, for DHCP users to come online properly, do not configure the ip subscriber initiator arp enable command on the access interface.

· For a DHCPv4 relay agent, you must perform the following tasks:

? Use the dhcp relay client-information record command to enable recording client information in relay entries.

? Use the undo dhcp relay client-information refresh enable command to disable the DHCP relay agent from periodically refreshing dynamic relay entries.

? Use the dhcp select relay proxy command on the DHCP relay agent interface to enable DHCP server proxy on the relay agent.

· For a DHCPv6 relay agent, you must use the ipv6 dhcp relay client-information record command to enable recording client information in DHCPv6 relay entries.

In an IPoE application, the advertisement push function takes effect only on HTTP packets using port number 80 and HTTPS packets using port number 443.

Enabling IPoE and setting the IPoE access mode

Restrictions and guidelines

To change the IPoE access mode, disable IPoE, and then set the new IPoE mode when you enable IPoE.

IPoE configurations for the IPv4 or IPv6 protocol stack take effect on an interface only when IPoE is enabled on the interface for the IPv4 or IPv6 protocol stack.

For interface-leased users, L2VPN-leased users, and dual-stack static users to come online, you must enable IPoE for both IPv4 and IPv6 protocol stacks.

In an IPv4 network, when IPoE operates in Layer 2 mode, you must execute the gateway-list export-route command in DHCP pool view to specify the gateway address for users. Do not specify the gateway address for users through configuring an IP address for the access interface.

Procedure

1. Enter system view.

system-view

2. Enter interface view.

interface interface-type interface-number

3. Enable IPoE and set the IPoE access mode on an interface.

ip subscriber { l2-connected | routed } enable [ ipv4 | ipv6 ]

By default, IPoE is disabled.

If you do not specify the ipv4 or ipv6 keyword, this command enables IPoE for both IPv4 and IPv6 protocol stacks.

Configuring the authentication method

About IPoE authentication methods

IPoE supports the following authentication methods:

· Bind authentication—Authenticates users by the usernames and passwords that the BRAS automatically generates based on user location information. Bind authentication is applicable to all types of IPoE users.

· Web authentication—Authenticates users by the usernames and passwords that users enter on the Web authentication page. Web authentication applies to only DHCP users and static users.

· Web MAC authentication—A user has to enter the username and password only for the first login. Then, the user can quickly come online without entering the username and password.

By default, bind authentication is configured for IPoE users. To perform Web authentication for IPoE users, you must configure Web authentication for the IPoE users.

When you switch the authentication method from bind authentication to Web authentication or Web MAC authentication, the device performs operations depending on the session type:

· For dynamic individual sessions, the device deletes all the dynamic individual sessions on the interface and logs out users.

· For interface-level static individual sessions:

? the device initializes all static individual sessions on the interface and logs out users.

· For global static individual sessions, the device deletes all global static individual sessions created on the interface and logs out users.

· For leased sessions:

? the device initializes all leased sessions on the interface and logs out users.

When you switch the authentication method from Web authentication or Web MAC authentication to bind authentication or between Web authentication and Web MAC authentication on an interface, the device performs the following operations:

· Deletes DHCP dynamic individual sessions and global static individual sessions on the interface and initializes the static individual sessions on the interface.

· Logs out users.

Restrictions and guidelines

When IPoE Web authentication and portal authentication are both configured on an interface, only IPoE Web authentication takes effect. The configuration of IPoE Web authentication does not affect an online portal user. When the portal user goes offline, the user cannot access the interface through portal authentication again. For more information about portal authentication, see "Configuring portal authentication."

When a DHCP user or static user comes online through Web authentication, the user can use common Web authentication, transparent MAC-trigger authentication, and transparent MAC authentication. When multiple authentication methods are configured, an authentication method is selected as follows:

· If Web authentication is configured on an interface, the following rules apply:

? If no MAC binding server is configured by using the portal apply mac-trigger-server command on the interface, the DHCP user or static user uses common Web authentication.

? If a MAC binding server is configured by using the portal apply mac-trigger-server command on the interface, the DHCP user or static user uses transparent MAC-trigger authentication.

· If Web MAC authentication is configured on an interface, the DHCP user or static user uses transparent MAC authentication no matter whether a MAC binding server is configured by using the portal apply mac-trigger-server command on the interface.

In the current software version, only DHCP users support Layer 3 transparent authentication, and static users do not support Layer 3 transparent authentication.

Procedure

Configuring a dynamic individual session initiation method

About dynamic individual session initiation methods

Dynamic individual session initiation methods include unclassified-IP packet initiation, IPv6 ND RS packet initiation, and DHCP packet initiation. After IPoE is enabled on an interface, the BRAS drops packets from users by default. You must configure a dynamic individual session initiation method on the interface to initiate IPoE sessions. You can configure multiple dynamic individual session initiation method on an interface.

Restrictions and guidelines

IPv6 ND RS packet initiation requires the BRAS to send IPv6 ND RA packets. As a best practice, make sure the interval for sending IPv6 ND RA packets is no less than 6 minutes.

IPv6 ND RS packet initiation supports only hosts that use Layer 2 access mode.

As a best practice, configure both unclassified-IPv6 packet initiation and IPv6 ND RS packet initiation for an IPv6 interface. PCs running Windows generate IPv6 addresses randomly or using the EUI-64 method. Unclassified-IPv6 packet initiation supports packets with randomly-generated IPv6 addresses. IPv6 ND RS packet initiation supports packets with EUI-64-generated IPv6 addresses.

Procedure

1. Enter system view.

system-view

2. Enter interface view.

By default, no IPv4 dynamic individual session initiation method is enabled.

4. Configure an IPv6 dynamic individual session initiation method.

ip subscriber initiator { dhcpv6 | ndrs | unclassified-ipv6 } enable

By default, no IPv6 dynamic individual session initiation method is enabled.

Configuring authentication user naming conventions for dynamic individual users

About authentication user naming conventions for dynamic individual users

Usernames configured for dynamic individual users must be the same as those configured on the AAA server.

For dynamic individual users using bind authentication, usernames are selected in the following order:

1. Username configured by using the command specific to the users.

? For DHCP users, username obtained by using the ip subscriber dhcp username command.

? For ND RS users, username obtained by using the ip subscriber ndrs username command.

? For unclassified-IP users and static individual users, username obtained by using the ip subscriber unclassified-ip username command.

2. Username configured by using the ip subscriber username command.

3. Default user name.

? For DHCP users, MAC address of the user. If the user MAC address cannot be obtained, the source MAC address of packets is used.

? For ND RS users, source MAC address of packets.

? For unclassified-IP users and static individual users, source IP address of packets.

For Web authentication and Web MAC authentication in the preauthentication phase, usernames are selected for dynamic individual users in the order usernames are selected for dynamic individual users using bind authentication.

For Web authentication in the Web authentication phase, usernames are selected in the following order for dynamic individual users:

1. Username that the user enters when logging in.

2. Username configured by using the ip subscriber username command.

3. Default user name.

? For DHCP users, MAC address of the user. If the user MAC address cannot be obtained, the source MAC address of packets is used.

? For ND RS users, source MAC address of packets.

For Web MAC authentication in the Web authentication phase, usernames are selected in the following order for dynamic individual users:

1. Username configured by using the ip subscriber username command.

2. Default user name.

? For DHCP users, MAC address of the user. If the user MAC address cannot be obtained, the source MAC address of packets is used.

? For ND RS users, source MAC address of packets.

Procedure

1. Enter system view.

system-view

2. Enter interface view.

interface interface-type interface-number

3. Configure an authentication user naming convention for DHCP users.

ip subscriber dhcp username include { circuit-id [ separator separator ] | client-id [ separator separator ] | hostname [ original ] [ separator separator ] | nas-port-id [ separator separator ] | port [ separator separator ] | remote-id [ separator separator ] | second-vlan [ separator separator ] | slot [ separator separator ] | source-mac [ address-separator address-separator ] [ separator separator ] | string string [ separator separator ] | subslot [ separator separator ] | sysname [ separator separator ] | vendor-class [absent-replace | original ] * [ separator separator ] | separator vendor-specific [ separator separator ] | vlan [ separator separator ] } *

By default, no authentication user naming conventions are configured for DHCP users.

For DHCPv4 users accessing in loose mode, the packets do not carry DHCP Option information. Therefore, the circuit-id, mac, client-id, remote-id, vendor-class, absent-replace, original, or vendor-specific keyword does not take effect. Even these keywords are specified, usernames are generated according to the situation where these keywords are not specified. DHCPv6 users cannot access in loose mode.

4. Configure an authentication user naming convention for unclassified-IP users.

ip subscriber unclassified-ip username include { nas-port-id [ separator separator ] | port [ separator separator ] | second-vlan [ separator separator ] | slot [ separator separator ] | source-ip [ address-separator address-separator ] [ separator separator ] | source-mac [address-separator address-separator ] [ separator separator ] | string string [ separator separator ] | subslot [ separator separator ] | sysname [ separator separator ] | vlan [ separator separator ] } *

By default, no authentication user naming conventions are configured for unclassified-IP users.

5. Configure an authentication user naming convention for IPv6 ND RS users.

ip subscriber ndrs username include { nas-port-id [ separator separator ] | port [ separator separator ] | second-vlan [ separator separator ] | slot [ separator separator ] | source-mac [ address-separator address-separator ] [ separator separator ] | string string [ separator separator ] | subslot [ separator separator ] | sysname [ separator separator ] | vlan [ separator separator ] } *

By default, no authentication user naming conventions are configured for IPv6 ND RS users.

6. Configure the username for IPoE individual users.

ip subscriber username { mac-address [ address-separator address-separator ] [ lowercase | uppercase ] | string string }

By default, no username is configured for IPoE individual users.

To avoid configuring usernames for each initiation method separately when multiple individual session initiation methods are configured on an interface, you can use this command to uniformly configure authentication usernames for all individual users on an interface.

Configuring passwords for dynamic individual users

About passwords for dynamic individual users

The password selection rule for DHCPv4 users in this section applies to only DHCPv4 users accessing in non-loose mode. For how the password is selected for DHCPv4 users accessing in loose mode, see Layer 2—WAN Access Command Reference. For information about accessing in loose mode, see "Allowing dynamic users to access in loose mode."

Passwords configured for dynamic individual users must be the same as those configured on the AAA server.

For dynamic individual users using bind authentication, passwords are selected in the following order:

1. Password obtained by using the ip subscriber dhcp password and ip subscriber dhcpv6 password option16 commands. (Applicable to only DHCP users.)

2. Password configured by using the ip subscriber password command.

3. The string vlan.

For Web authentication and Web MAC authentication in the preauthentication phase, passwords are selected for dynamic individual users in the same order passwords are selected for dynamic individual users using bind authentication.

For Web authentication in the Web authentication phase, passwords are selected in the following order for dynamic individual users:

1. Password that the user enters when logging in.

2. Password configured by using the ip subscriber password command.

3. The string vlan.

For Web MAC authentication in the Web authentication phase, passwords are selected in the following order for dynamic individual users:

1. Password configured by using the ip subscriber password command.

2. The string vlan.

Procedure

system-view

2. Enter interface view.

interface interface-type interface-number

3. Set the password for dynamic individual users.

ip subscriber password { mac-address [ address-separator address-separator ] [ lowercase | uppercase ] | { ciphertext | plaintext } string

The default password for dynamic individual users is vlan.

To avoid configuring passwords for each initiation method separately when multiple individual session initiation methods are configured on an interface, you can use this command to uniformly configure authentication passwords for all individual users on an interface.

4. Specify a string from the DHCPv4 as the password for DHCPv4 users.

ip subscriber dhcp password { circuit-id mac | option60 [ offset offset ] [ length length ] | user-class } }

By default, the BRAS does not use the password specified in DHCPv4 packets for DHCP users.

Configure Option 60 or Option 77 as the trusted DHCP option for the password specified by using this command to take effect. For more information about Option 60 or Option 77, see "Configuring trusted DHCP options for DHCP users."

5. Specify a string from the Option 16 or Option 17 as the password for DHCPv6 users:

ip subscriber dhcpv6 password option16 [ offset offset ] [ length length ]

By default, the BRAS does not use the password specified in Option 16 or Option 17 for DHCPv6 users.

Configure DHCPv6 Option 16 or Option 17 as the trusted DHCP option for the password specified by using this command to take effect. For more information about Option 16 or Option 17, see "Configuring trusted DHCP options for DHCP users."

Configuring ISP domains for dynamic individual users

About configuring ISP domains for dynamic individual users

The ISP domain selection rule in this section applies to only IPoE users accessing in non-loose mode. For how the ISP domain is selected for IPoE users accessing in loose mode, see Layer 2—WAN Access Command Reference. For information about accessing in loose mode, see "Allowing dynamic users to access in loose mode."

In bind authentication, a dynamic individual user can obtain ISP domains in various ways. An ISP domain is selected for a dynamic individual user in the following order (steps 1 and 2 apply to only DHCP users, and step 3 applies to only DHCP users and unclassified-IP users):

1. Forced ISP domain configured by using the ip subscriber dhcp domain command. If the domain does not exist, proceed with step 5. (Applicable to only DHCP users.)

2. Information obtained from the option. (Applicable to only DHCP users.)

For a DHCPv4 user, an ISP domain in information obtained from the option is selected in the following order:

a. ISP domain generated based on the domain name generation rule configured by the ip subscriber dhcp domain include command if the following conditions exist:

- The string selected from Option 60 contains the trusted domain.

- The BRAS trusts Option 60.

- The interface is configured with the ip subscriber dhcp domain include command.

If the ISP domain does not exist, proceed with step 3.

b. Trusted ISP domain configured by the ip subscriber dhcp option60 match command if the following conditions exist:

- The BRAS trusts Option 60.

- The interface is not configured with the ip subscriber dhcp domain include command.

If the ISP domain does not exist, proceed with step 3.

c. ISP domain selected according to the rule for packets that do not carry Option 60 if the following conditions exist:

- The BRAS trusts Option 60.

- The string selected from Option 60 does not contain the trusted domain.

In this case, the contents of Option 60 are ignored and not used for generating a domain name.

If the ISP domain does not exist, proceed with step 3.

d. ISP domain generated based on the domain name generation rule configured by the ip subscriber dhcp domain include command if the following conditions exist:

- The BRAS trusts Option 60.

- The interface is not configured with the ip subscriber dhcp option60 match command.

- Option 60 does not contain the slash (/), back slash (\), vertical bar (|), quotation mark ("), colon (:), asterisk (*), question mark (?), left angle bracket (<), or right angle bracket (>).

- The interface is configured with the ip subscriber dhcp domain include command.

If the ISP domain does not exist, proceed with step 3.

e. ISP domain automatically selected from Option 60 if the following conditions exist:

- The BRAS trusts Option 60.

- The interface is not configured with the ip subscriber dhcp option60 match or ip subscriber dhcp domain include command.

- All information in Option 60 does not contain invalid characters. Invalid characters include the slash (/), back slash (\), vertical bar (|), quotation mark ("), colon (:), asterisk (*), question mark (?), left angle bracket (<), and right angle bracket (>).

If the ISP domain does not exist, proceed with step 3.

For a DHCPv6 user, an ISP domain in information obtained from the option is selected in the following order:

a. Trusted ISP domain configured by the ip subscriber dhcpv6 option16 match command if the following conditions exist:

- The string selected from Option 16 contains the trusted domain.

- The BRAS trusts Option 16.

If the ISP domain does not exist, proceed with step 3.

b. ISP domain selected according to the rule for packets do not carry Option 16 if the following conditions exist:

- The BRAS trusts Option 16.

- The interface is configured with the ip subscriber dhcpv6 option16 match command, but the specified string cannot be matched in the specified position of Option 16. Or, the interface is not configured with the ip subscriber dhcpv6 option16 match command.

- All information in Option 16 does not contain invalid characters. Invalid characters include the slash (/), back slash (\), vertical bar (|), quotation mark ("), colon (:), asterisk (*), question mark (?), left angle bracket (<), and right angle bracket (>).

If the ISP domain does not exist, proceed with step 3.

3. Service-specific ISP domain. If the ISP domain does not exist, proceed with step 5. (Applicable to only DHCP users and unclassified-IP users.)

4. ISP domain configured by using the domain configuration command specific to the user:

? For a DHCP user, non-forced ISP domain configured by using the ip subscriber dhcp domain command. If the domain does not exist, proceed with step 5.

? For an unclassified-IP user, ISP domain configured by using the ip subscriber unclassified-ip domain command. If the domain does not exist, proceed with step 5.

? For an IPv6 ND RS user, ISP domain configured by using the ip subscriber ndrs domain command. If the domain does not exist, proceed with step 5.

By default, the dynamic individual session limit is not configured.

When this command is configured together with the ip subscriber max-session command, the two commands both take effect. The two commands control sessions in different perspectives, and the number of sessions is controlled by both commands. A new session can be established only when neither limit is reached. For more information about the ip subscriber max-session command, see "Setting the maximum number of individual sessions and leased subuser sessions on an interface."

Configuring trusted DHCP options for DHCP users

About trusted DHCP options for DHCP users

This feature enables a BRAS to obtain user access information from trusted DHCP options when the BRAS acts as a DHCP relay agent. The BRAS includes the obtained user access information in the RADIUS attributes sent to the RADIUS server based on the following matrix.

Table 1 Associated DHCP options for RADIUS attributes

RADIUS attributes	Associated DHCP options
NAS-PORT-ID	· DHCPv4 Option 82 Circuit-ID · DHCPv6 Option 18
DSL_AGENT_CIRCUIT_ID	· DHCPv4 Option 82 Circuit-ID · DHCPv6 Option 18
DSL_AGENT_REMOTE_ID	· DHCPv4 Option 82 Remote-ID · DHCPv6 Option 37

By default, the BRAS uses the ASCII format to parse the circuit-ID and remote-ID fields in Option 82, Option 18, and Option 37. For more information about the circuit-ID and remote-ID parsing formats, see "Configuring the parsing format for the circuit ID and remote ID in the DHCP option."

If the BRAS trusts DHCPv4 Option 60, DHCPv6 Option 16, and DHCPv6 Option 17, IPoE can use the ISP domains specified in the options when certain conditions exist. For more information about selecting ISP domains, see "Configuring ISP domains for dynamic individual users."

By default, the BRAS does not trust DHCP options.

On the same interface, you can execute this command multiple times to configure multiple trusted options. However, you cannot configure the interface to trust both Option 16 and Option 17. For example, if you have configured Option 16 as a trusted option, you cannot configure Option 17 as a trusted option.

Configuring the parsing format for the circuit ID and remote ID in the DHCP option

About the parsing format for the circuit ID and remote ID in the DHCP option

For IPoE to correctly parse information in the circuit ID and remote ID, perform this task to set a proper parsing format according to the format of the circuit ID and remote ID information sent by downstream devices.

Configuring trusted ISP domains for DHCP users

About trusted ISP domains for DHCP users

If DHCP packet initiation is enabled and portal authentication is configured, the following situations occur:

· If the string selected from Option 60/Option 16/Option 17 contains the trusted ISP domain, DHCP packet initiation triggers IPoE authentication and selects an ISP domain for IPoE authentication as follows:

a. Forced ISP domain. If the ISP domain does not exist, proceed with step d.

b. When Option 60/Option 16/Option 17 in DHCP packets is trusted, the following rules apply:

- If the domain name generation rule is configured, the domain name generated according to the generation rule is used.

- If no domain name generation rule is configured, the trusted ISP domain is used.

For information about domain name generation rules, see "Configuring domain name generation rules for dynamic IPoE DHCP users."

c. When the interface is not configured to trust Option 60/Option 16/Option 17 in DHCP packets, for how to select an ISP domain, see "Configuring ISP domains for dynamic individual users."

d. ISP domain selected by the AAA module. For more information, see "Configuring AAA."

· If the string selected from Option 60/Option 16/Option 17 does not contain the trusted ISP domain, DHCP packet initiation uses portal authentication.

For more information about portal authentication, see "Configuring portal authentication."

Restrictions and guidelines

Configure trusted DHCP options before you configure the trusted ISP domains. For more information about configuring trusted DHCP options, see "Configuring trusted DHCP options for DHCP users."

By default, no trusted ISP domain is configured for DHCPv6 users.

Configuring domain name generation rules for dynamic IPoE DHCP users

About domain name generation rules for dynamic IPoE DHCP users

In some scenarios, the access information and Option 60 must be combined as an ISP domain for authentication. For example, user A and user B belong to different VLANs but have the same Option 60 and come online through the same interface. To assign user A and user B to different ISP domains and authorize different address pools based on ISP domains, you can use this feature. This feature can generate ISP domain names by using the Option 60 + VLAN combination.

If the DHCP users use information in Option 60 as the ISP domains and a domain name generation rule is configured, the parameters configured in this generation rule are used for generating the ISP domain names. The domain name generated is Field in Option 60 used as the ISP domain name + parameters configured in this rule. If Option 60 is trusted, the fields in Option 60 are selected for generating ISP domains as follows:

· If the ip subscriber dhcp option60 match command is configured, the following rules apply:

? If the string selected from Option 60 contains the trusted domain, the trusted domain is used for generating the ISP domain names.

? If the string selected from Option 60 does not contain the trusted domain, the contents of Option60 are ignored and not used as ISP domains. In this case, an ISP domain name is selected according to the rule for packets that do not carry Option 60.

· If the ip subscriber dhcp option60 match command is not configured, the string selected by using the ip subscriber trust option60 command is used for generating the ISP domain names.

Restrictions and guidelines

To configure this feature on an interface, you must configure the interface to trust Option 60. For Option 60 configuration, see "Configuring trusted ISP domains for DHCP users."

Procedure

By default, no domain name generation rule is configured for DHCPv4 users.

Allowing abnormally logged out DHCP users to come online again through packet initiation

About

For a BRAS to record information about abnormally logged out DHCP users on an interface, you must enable unclassified-IP packet initiation or ARP packet initiation on the interface. When the BRAS receives IP packets or ARP packets from an abnormally logged out user, the BRAS can restore the IPoE session for the user based on the recorded DHCP user information.

A DHCP user is abnormally logged out if the IPoE session of the user is deleted for a reason except the user actively releases its IP address.

Restrictions and guidelines

When an interface receives IP or ARP packets of a user that match both an IPoE static session and the abnormally logged out DHCP user records, the user comes online as a static user.

For an abnormally logged out DHCP user to come online again through packet initiation on an interface, do not disable DHCP packet initiation, and you must authorize the corresponding DHCP address pool through the authentication domain or AAA server of the user.

When a Web authentication user comes online again after being abnormally logged out, only the session in the preauthentication domain can be recovered. For the user to come online during the Web authentication phase, the user must undergo the normal Web authentication process.

This feature supports only abnormally logged out DHCPv4 users in the current software version.

Any of the following operations can clear the abnormally logged out DHCP user records on an interface:

· Disabling unclassified-IP packet initiation or ARP packet initiation on the interface.

· Disabling IPoE on the interface.

· Disabling DHCP packet initiation on the interface.

· Deactivating the interface (including plugging the slot or subslot of the interface, and deleting the global interface or subinterface through which the user comes online).

Procedure

? Enable ARP packet initiation.

ip subscriber initiator arp enable

By default, ARP packet initiation is disabled.

4. (Optional.) Configure the lease expiration time when the abnormally logged out user logs in again as the time when the user is logged out.

ip subscriber lease-end-time original

By default, the lease expiration time is renewed when the abnormally logged out user logs in again.

Configuring trusted source IP addresses for unclassified-IP users

About trusted source IP addresses for unclassified-IP users

When unclassified-IP packet initiation is enabled and portal authentication is configured, a user comes online as a static IPoE user if the unclassified-IPv4 packets match a static IPoE session. Otherwise, the following rules apply:

· IPoE authentication is available only for unclassified-IP users who send packets with the trusted source IP addresses.

· Portal authentication is available for unclassified users who send packets with untrusted source IP addresses.

For more information about portal authentication, see "Configuring portal authentication."

If unclassified-IP packet initiation is enabled but portal authentication is not configured on an interface, a user comes online as a static IPoE user if the unclassified-IPv4 packets match a static IPoE session. Otherwise, unclassified-IP packets with untrusted source IP addresses are dropped. Only unclassified-IP packets with trusted source IP addresses can initiate IPoE authentication.

Allowing dynamic users to access in loose mode

About allowing dynamic users to access in loose mode

When the sessions of online IPoE users are deleted because the system or the slot where the access interface resides is rebooted, DHCP users will not send DHCP packets to trigger access again because these user cannot sense the reboot. As a result, the access device cannot regenerate DHCP sessions for these users. To solve this problem, you can specify IPoE users to access in loose mode.

For users accessing in loose mode through a global interface or physical interface, the definition of reboot is different as follows:

· For users accessing through a global interface: After the system is rebooted, IPoE users can use IP packets and ARP packets to trigger access and generating DHCP sessions within the duration specified by the loose-time argument or all time.

· For users accessing through a physical interface: After the slot where the physical interface resides is rebooted, IPoE users can use IP packets and ARP packets to trigger access and generating DHCP sessions within the duration specified by the loose-time argument or all time.

Restrictions and guidelines

During the loose access duration after the system or the slot where the access interface resides is rebooted, the interface processes the packets in the following order when an interface receives IP or ARP packets from a user:

1. If the packets match a configured IPoE static session, the user is processed as a static user.

2. If the packets match abnormally logged out DHCP user records, the interface restores the session information for the abnormally logged out DHCP user according to the recorded information.

3. If the packets match a roaming-capable user, the user is processed as a roaming user.

4. The user accesses in loose mode.

IPoE DHCP users can access in loose mode only when all the following conditions exist:

· The Layer 2 access mode is configured on the access interface.

· DHCPv4 packet initiation is enabled on the access interface.

· A DHCPv4 address pool is assigned to users through the authentication domain or AAA server.

· To use IP packet initiation, you must configure the ip subscriber initiator unclassified-ip enable command on the access interface, and as a best practice, specify the matching-user keyword.

· To use ARP packet initiation, you must configure the ip subscriber initiator arp enable command and the ip subscriber initiator unclassified-ip enable command on the access interface, and as a best practice, specify the matching-user keyword.

In the current software version, only dynamic IPv4 IPoE users can access in loose mode.

For IPoE Web authentication users that access in loose mode, only the sessions in the preauthentication domain can be regenerated. To come online in the Web authentication phase, these users must follow the normal Web authentication procedure.

For IPoE to operate properly when IPoE users access in loose mode, do not configure portal on access interfaces of these IPoE users.

Configuring static individual users

Static individual user tasks at a glance

To configure static individual users, perform the following tasks:

1. Configuring a static individual session initiation method

2. Configuring static individual sessions

3. (Optional.) Configuring authentication user naming conventions for static individual users

4. (Optional.) Configuring passwords for static individual users

5. (Optional.) Configuring ISP domains for static individual users

Configuring a static individual session initiation method

About static individual session initiation methods

For IP packets to initiate static individual sessions, you must enable unclassified-IP packet initiation.

To enable static individual session information to match ARP packets, you must enable ARP packet initiation. Disabling ARP packet initiation does not affect online ARP-initiated static individual users.

For NS or NA packets to initiate IPv6 static individual sessions, you must enable NS/NA packet initiation. Disabling NS/NA packet initiation does not affect online NS/NA-initiated static individual users.

Restrictions and guidelines

The gateway IP address allocated to the static individual users must be one of the following IP addresses:

· The IP address of the access interface.

· A gateway address from the gateway address list specified by using the gateway-list export-route command.

For a user to initiate a session by using NS/NA packets, execute one of the following commands:

· Execute the ip subscriber initiator unclassified-ipv6 enable command to enable unclassified-IPv6 packet initiation.

· Execute the ip subscriber initiator nsna enable command to enable NS/NA packet initiation.

When both commands are configured, the following rules apply:

· In Layer 2 access mode, if the source IPv6 address of received NS or NA packets is a global unicast address and the target IPv6 address is a non-multicast address, unclassified-IP packet initiation is used. Otherwise, matching NS or NA packets can initiate sessions, and unmatching NS or NA packets are dropped.

· In Layer 3 access mode, NS or NA packets can only initiate sessions by using the NS/NA packet initiation method and cannot initiate sessions by using the unclassified-IPv6 initiation method.

Configuring static individual sessions

About static individual sessions

Static individual users initiate IPoE sessions by sending IP, ARP, NS, or NA packets. If an IP or ARP packet matches a manually configured IPoE session, the BRAS authenticates the user and establishes an IPoE session.

Interface-level static individual sessions take precedence over global static individual sessions.

Restrictions and guidelines

In the public network or the same VPN instance, a maximum of one IPoE static session can be configured for one IP address.

For interface-level static sessions and global static sessions with interfaces specified, the IP address and interface combination of an IPoE static session must be unique in the public network and all VPN instances.

For global static sessions without interfaces specified, the IP address of a global IPoE static session must be unique in the public network and all VPN instances.

Configuring an ISP domain for Web authentication individual users

About configuring a preauthentication ISP domain for DHCP users

IPoE Web authentication process includes preauthentication and Web authentication phases. Web authentication is triggered when users pass preauthentication. The preauthenticated users obtain IP addresses (applicable to only DHCP users) and authorization attributes configured for the preauthentication domain. Web authentication is triggered when preauthenticated users access an unauthorized HTTP/HTTPS address.

You can modify the preauthentication ISP domain. By default, the BRAS selects a preauthentication ISP domain in the following order:

· For static users:

a. Authentication domain configured by using the ip subscriber session static command. If the domain does not exist, proceed with step e.

b. Preauthentication domain configured by using the ip subscriber pre-auth domain command. If the domain does not exist, proceed with step e.

c. Service-specific domain. If the domain does not exist, proceed with step e.

d. Domain configured by using the ip subscriber unclassified-ip domain command. If the domain does not exist, proceed with step e.

e. ISP domain selected by the AAA module. For more information, see "Configuring AAA."

· For dynamic DHCP and ND RS users:

a. Service-specific domain. If the domain does not exist, proceed with step c.

b. Preauthentication domain configured by using the ip subscriber pre-auth domain command. If the domain does not exist, proceed with step c.

c. ISP domain selected by the AAA module. For more information, see "Configuring AAA."

When Web authentication is used, if multiple types of ISP domains are configured, an ISP domain is selected in the following order during the Web authentication phase:

1. If the ip subscriber web-auth domain command is used to specify a Web authentication domain, the device first obtains the domain in the username and operates as follows:

? If the username carries a domain and the carried domain exists, the domain carried in the username is used. If the domain does not exist, proceed with step 2.

? If the username does not carry a domain, the Web authentication domain specified by using the ip subscriber web-auth domain command is used. If the specified domain does not exist, proceed with step 2.

If no domain is specified for Web authentication, proceed with step 2.

2. ISP domain selected by the AAA module. For more information, see "Configuring AAA."

When Web MAC authentication is used, if multiple types of ISP domains are configured, an ISP domain is selected in the following order during the Web authentication phase:

1. If the ip subscriber mac-auth domain command is used to specify a MAC authentication domain, the device first obtains the domain in the username and operates as follows:

? If the username carries a domain and the carried domain exists, the domain carried in the username is used. If the domain does not exist, proceed with step 3.

? If the username does not carry a domain, the MAC authentication domain specified by using the ip subscriber mac-auth domain command is used. If the specified domain does not exist, proceed with step 3.

This step applies to only transparent MAC authentication.

2. If the ip subscriber web-auth domain command is used to specify a Web authentication domain, the device first obtains the domain in the username and operates as follows:

? If the username carries a domain and the carried domain exists, the domain carried in the username is used. If the domain does not exist, proceed with step 3.

3. ISP domain selected by the AAA module. For more information, see "Configuring AAA."

The ISP domain configured for Web authentication applies to only users using Web authentication and Web MAC authentication during the Web authentication phase.

Configuring HTTP packet fast reply

About HTTP packet fast reply

When a user using a browser to perform Web authentication does not access the portal Web server, the access device will redirect the HTTP requests to the CPU. Then, the CPU pushes the Web authentication page of the portal Web server to the user. If an attacker sends a large number of HTTP requests to the device, the device suffers DoS attacks.

With this feature enabled on an interface, the device uses hardware to recognize HTTP requests and automatically responds with HTTP replies. This feature reduces the workload of the CPU and prevents DoS attacks.

Restrictions and guidelines

This feature is available only on CSPEX (except CSPEX-1104-E) and CEPC cards.

This feature does not immediately take effect on users that have passed preauthentication and come online before this feature is enabled. This feature takes effect only when these users go offline and come online again after passing preauthentication or return to the preauthentication domain after passing Web authentication.

With both this feature and transparent authentication configured, a user first attempts to come online through transparent authentication. The hardware responds and pushes the Web authentication page if the user fails to come online through transparent authentication for one of the following reasons:

· Transparent authentication binding query request times out.

· The portal server returns a message showing that the user is not bound.

· The AAA server returns authentication failure.

Procedure

Configuring an SSL server policy for HTTPS redirection

About SSL server policy for HTTPS redirection

When a DHCP user uses HTTPS packets to trigger Web authentication, you can use the default SSL server policy or customize an SSL server policy.

Procedure

1. Configure a PKI policy, and successfully apply for or import local certificates and CA certificates. For more information, see PKI configuration in Security Configuration Guide.

2. Configure an SSL server policy named https_redirect, and specify the policy to use an existing PKI domain.

You must install a certificate that the browser trusts. Otherwise, the browser displays the alarm that "The used certificate is insecure" when you set up an SSL connection to the device on the browser. For more information, see SSL configuration in Security Configuration Guide.

Configuring URL redirection

About URL redirection

This feature pushes authentication pages to users based on the user-requested URL or User-Agent information.

A URL redirection match rule matches HTTP or HTTPS requests by user-requested URL or User-Agent information, and redirects the matching HTTP or HTTPS requests to the specified redirection URL.

For a user to successfully access a redirection URL, configure a preauthentication domain user group ACL to allow HTTP or HTTPS requests destined for the redirection URL to pass.

You can configure the web-server url command in an ISP domain and the ip subscriber if-match command for URL redirection. The web-server url command redirects all HTTP or HTTPS requests from unauthenticated users to the Web server for authentication. The ip subscriber if-match command allows for flexible URL redirection by redirecting specific HTTP or HTTPS requests to specific redirection URLs. If both commands are executed, the ip subscriber if-match command takes priority to perform URL redirection.

Procedure

1. Configure an ACL to permit HTTP or HTTPS packets destined for the redirection URL.

For more information about configuring ACLs, see ACL and QoS Configuration Guide.

Configuring Web authentication fail-permit

About Web authentication fail-permit

With this feature configured, when the device detects that the Web authentication server or AAA server is unreachable, the device allows users to access network resources without Web authentication. You can implement Web authentication fail-permit by associating a fail-permit user group with a track entry.

By default, the Web authentication users that come online in the preauthentication domain belong to the user group authorized by AAA or authorized in the ISP domain when the users come online. After a fail-permit user group is associated with a track entry, the following rules apply:

· When the status of the track entry becomes Negative, the access device moves all online users in the current preauthentication domain from the authorized user group to the fail-permit user group. Then, the users can access network resources according to the privilege of the fail-permit user group.

· When the status of the track entry becomes Positive, the access device will move all online users in the current preauthentication domain back to the authorized user group. Then, the users can access network resources only after passing Web authentication.

Restrictions and guidelines

This command takes effect only on users in the preauthentication domain.

Procedure

1. Configure a track entry.

Track can monitor the server status in various method, such as NQA and BFD. For more information, see track configuration in High Availability Configuration Guide.

Setting the maximum number of individual sessions and leased subuser sessions on an interface

About the maximum number of individual sessions and leased subuser sessions on an interface

This feature controls the maximum number of individual users (including dynamic individual users and static individual users) and leased subusers on an interface.

Restrictions and guidelines

When the number of individual sessions and leased subuser sessions on an interface has reached the limit, new IPoE sessions cannot be established. The number of IPoE sessions created includes the number of IPv4 single-stack users, the number of IPv6 single-stack users, and the number of dual-stack sessions. A single-stack user occupies one session resource, and a dual-stack user occupies one session resource. If a single-stack user has come online successfully, the other stack of the same user can directly come online, and the two stacks share one session resource.

If the configured limit is smaller than the number of existing sessions on an interface, the configuration succeeds and the existing sessions are not affected. However, new sessions cannot be initiated on the interface.

Procedure

1. Enter system view.

system-view

2. Enter interface view.

interface interface-type interface-number

3. Set the maximum number of individual sessions and leased subuser sessions on the interface.

When this command is configured together with the ip subscriber { dhcp | dhcpv6 | ndrs | unclassified-ip | unclassified-ipv6 } max-session command, the two commands both take effect. The two commands control sessions in different perspectives, and the number of sessions is controlled by both commands. A new session can be established only when neither limit is reached. For more information about the ip subscriber { dhcp | dhcpv6 | ndrs | unclassified-ip | unclassified-ipv6 } max-session command, see "Setting the dynamic individual session limit."

Configuring service-specific ISP domains

About configuring service-specific ISP domains

6. Bind an ISP domain to IPoE users who send IP packets with the specified DSCP values.

ip subscriber dscp dscp-value-list domain domain-name

By default, no ISP domain is bound to IPoE users who send IP packets with the specified DSCP values.

For this command, IPoE users include DHCP users, unclassified-IP users, and static individual users.

Configuring the quiet feature for users

About the quiet feature

If this feature is enabled, the quiet timer starts when number of consecutive authentication failures of a user reaches the limit in the specified period. During the quiet timer period, packets from the user are dropped. After the quiet timer expires, the BRAS performs authentication upon receiving a packet from the user. This feature can prevent password attacks.

Restrictions and guidelines

If no dual-stack IPoE session is generated for a dual-stack user, the authentication failures of the two protocol stacks are counted separately. The dual-stack user is quieted only when the number of consecutive authentication failures reaches the limit in the specified period for each protocol stack.

If a dual-stack IPoE session is generated for a dual-stack user, the authentication failures of the two protocol stacks are counted together. The dual-stack user is quieted when the number of consecutive authentication failures reaches the limit in the specified period.

Procedure

1. Enter system view.

ip subscriber authentication chasten auth-failure auth-period

By default, the quiet timer starts immediately upon one authentication failure.

Configuring online detection for IPoE users

About configuring online detection for IPoE users

Online detection enables the BRAS to periodically detect the status of a user. It uses ARP or ICMP requests to detect IPv4 users, and uses NS packets of the ND protocol or ICMPv6 requests to detect IPv6 users.

After you configure online detection, the BRAS starts a detection timer to detect online users. If the BRAS receives no user packets from a user when the timer expires, it sends a detection packet to the user and performs the following operations:

· If the BRAS receives user packets within the maximum number of detection attempts, the BRAS assumes the user is online. It resets the timer, and starts the next detection attempt.

· If the BRAS receives no user packets within the maximum number of detection attempts, the BRAS assumes the user is offline and deletes the session.

Restrictions and guidelines

This feature supports only individual users and leased subusers in Layer 2 access mode.

When the accounting mode is merge for dual-stack users, the sum of IPv4 uplink traffic and IPv6 uplink traffic is used to determine whether the user uplink traffic is updated.

Procedure

1. Enter system view.

system-view

2. Enter interface view.

interface interface-type interface-number

3. Configure online detection for IPv4 users.

ip subscriber user-detect ip { arp | icmp } retry retries interval interval [ no-datacheck ]

By default:

? For leased subusers, no matter whether user uplink traffic is updated within a detection timer period, the BRAS sends packets to detect the online status of users after the detection timer expires.

? For other users, no detection packets are sent after the detection timer expires if user uplink traffic is updated within a detection timer period. If user uplink traffic is not updated within a detection timer period, the BRAS uses the ARP request packets to detect IPv4 protocol stack users.

? The BRAS performs a maximum of five detection attempts after the first detection failure. The detection timer is 120 seconds.

The no-datacheck keyword does not take effect on leased subusers.

4. Configure online detection for IPv6 users.

ip subscriber user-detect ipv6 { icmp | nd } retry retries interval interval [ no-datacheck ]

By default:

? For leased subusers, no matter whether user uplink traffic is updated within a detection timer period, the BRAS sends packets to detect the online status of users after the detection timer expires.

? The BRAS performs a maximum of five detection attempts after the first detection failure. The detection timer is 120 seconds.

The no-datacheck keyword does not take effect on leased subusers.

Configuring the interface-down policy for IPoE users on an interface

Configuring NAS-Port-ID binding for IPoE access users

About NAS-Port-ID binding for IPoE access users

A device uses information about the interface through which a user comes online to fill in the NAS-Port-ID attribute and sends it to the RADIUS server by default. In some special applications, when you need to manually specify the access interface information to be filled in the NAS-Port-ID attribute, you can use this command. For example, suppose the RADIUS server restricts user A's access to only interface A. When user A accesses through interface B and you do not want to modify the RADIUS server configuration, you can configure this command to use information about interface A to fill in the NAS-Port-ID attribute for user A and send the attribute to the RADIUS server.

When version 1.0 is specified as the NAS-Port-ID format, the interface specified in this feature will be used to fill in the access interface information chassis=NAS_chassis;slot=NAS_slot;subslot=NAS_subslot;port=NAS_port.

When version 2.0 is specified as the NAS-Port-ID format, the interface specified in this feature will be used to fill in the NAS information {eth|trunk|atm} NAS_chassis/NAS_slot/NAS_subslot/NAS_port.

When version 3.0 is specified as the NAS-Port-ID format, the interface specified in this feature will be used to fill in the NAS information SlotID/IfNO.

When version 4.0 is specified as the NAS-Port-ID format, the interface specified in this feature will be used to fill in the following NAS information:

· For IPv4 users: SlotID/IfNO/Option82 Circuit-ID.

· For IPv6 users: SlotID/IfNO/Option18.

Configuring IPoE logging and service maintenance

Enabling logging for IPoE users

About enabling logging for IPoE users

The IPoE logging feature enables the device to generate IPoE logs and send them to the information center. Logs are generated after a user comes online successfully, fails to come online, normally goes offline, or abnormally goes offline. A log entry contains information such as the username, IP address, interface name, inner VLAN, outer VLAN, MAC address, and failure causes. For information about the log destination and output rule configuration in the information center, see Network Management and Monitoring Configuration Guide.

Restrictions and guidelines

As a best practice, disable this feature to prevent excessive IPoE log output.

Procedure

1. Enter system view.

2. Enable logging for IPoE users.

ip subscriber access-user log enable [ successful-login | failed-login | logout [ normal ] [ abnormal ] ] *

By default, logging is disabled for IPoE users.

Configuring the per-slot user count trap feature

About this task

You can use this feature to set the per-slot user count alarm threshold. When the user count on a slot exceeds the threshold, an alarm is triggered automatically. Then, the administrator can promptly know the online user conditions of the network.

This feature counts only the number of IPoE users and PPPoE users.

· A dual-stack PPPoE user is counted as one user.

· A dual-stack IPoE user is counted as two users.

· For IPoE leased users, one interface-leased user is counted as two users, and one subnet-leased user is counted as one user.

· For IPoE leased subusers, one subuser is counted as one user.

Suppose the per-slot maximum user count allowed is a and the per-slot user count alarm threshold is b. The following rules apply:

· When the user count on a slot exceeds a×b, the alarm information is output.

· When the user count on a slot drops within the normal range, the alarm clearing information is output.

In some special cases, the user count on a slot frequently changes in the critical range, which causes frequent output of alarm information and alarm clearing information. To avoid this problem, the system introduces a buffer area when the user count on a slot drops below the threshold. The buffer area size is 10% of the threshold set. Suppose the buffer area size is c. Then, c=a×b÷10. When the user count on a slot drops below a×b-c, the alarm clearing information is output.

For example, suppose a is 1000 and b is 80%. Then, c= a×b÷10=1000×80%÷10=80.

· When the user count on a slot exceeds a×b=1000×80%=800, the alarm information is output.

· When the user count on a slot drops below a×b-c=800-80=720, the alarm clearing information is output.

The alarm information and alarm clearing information output both contain the logs and traps. For traps to be correctly sent to the NMS host, you must execute the snmp-agent trap enable slot-user-warning-threshold command in addition to configuring the SNMP alarm feature correctly.

Procedure

1. Enter system view.

system-view

2. Set the per-slot user count alarm threshold.

slot-user-warning-threshold threshold-value

By default, the per-slot user count alarm threshold is 100.

3. Enable the per-slot user count trap feature.

snmp-agent trap enable slot-user-warning-threshold

By default, the per-slot user count trap feature is disabled.

Configuring service tracing objects

About service tracing objects

You can create service tracing objects to trace access user information, such as login and logout information. By specifying match parameters, you can trace the specific access users.

Restrictions and guidelines

This feature is resource intensive. As a best practice, configure this feature only when troubleshooting devices.

When the log server is specified as the output destination, make sure the device and the specified log server can reach each other and the log server configuration is correct.

An active/standby switchover causes the service tracing object configuration to be ineffective.

Procedure

1. Enter system view.

system-view

2. Configure service tracing objects.

trace access-user object object-id { access-mode ipoe | c-vlan vlan-id | interface interface-type interface-number | ip-address ip-address | mac-address mac-address | s-vlan vlan-id | username user-name } * [ aging time | output { file file-name | syslog-server server-ip-address | vty } ] *

If you specify an interface, the service tracing object becomes ineffective when the slot or subslot that hosts the specified interface is rebooted.

Enabling roaming for IPoE individual users

About enabling roaming for IPoE individual users

Online IPoE individual users can roam between different interfaces or VLANs of the same subinterface.

To reduce roaming users' impact on other users, you can limit the roaming range by using a roaming group. An online user can roam only within the roaming group of the interface through which the user comes online. For example, user A and user B both use the IP address 1.1.1.1/24 and belong to the same VPN instance. User A first comes online on interface A through unclassified-IP packet initiation. Both interface A and interface B are enabled with roaming but not configured with roaming groups. In this case, when user B comes online on interface B through unclassified-packet initiation, the device will log off user A. For user A and user B to come online simultaneously, you can configure different roaming groups for interface A and interface B. This configuration isolates the roaming range of user A from the roaming range of user B.

Restrictions and guidelines

Make sure the user access interfaces before and after the roaming have IPoE enabled for the same protocol stacks and are configured with the same IPoE authentication method, authentication domain, and roaming group.

Typically, the following packets can trigger roaming: ARP packets, IPv4 packets, IPv6 packets, and DHCPv4/DHCP6 renewal packets (including Renew packets and Rebind packets).

In a roaming scenario, a user might send DHCP packets to request coming online after the physical location of the user changes.

· For a DHCPv4 user to come online through DHCPv4 packet initiation, execute the dhcp session-mismatch action fast-renew command.

· For a DHCPv6 user to come online through DHCPv6 packet initiation, execute the ipv6 dhcp session-mismatch action fast-renew command.

When an attacker uses a DHCP packet with a spoofing MAC address to request coming online, the corresponding normally online user might go offline, which causes a security invulnerability. Before executing the dhcp session-mismatch action fast-renew or ipv6 dhcp session-mismatch action fast-renew command, make sure no attacks exist in the network. For more information about this command, see DHCP commands and DHCPv6 commands in BRAS Services Command Reference.

In an IPv4 network:

· To use IPv4 packets to trigger roaming, you must configure the ip subscriber initiator unclassified-ip enable matching-user command on the target interface of roaming.

· To use ARP packets to trigger roaming, you must configure the ip subscriber initiator arp enable and ip subscriber initiator unclassified-ip enable matching-user commands on the target interface of roaming.

As a best practice for roaming in an IPv4 network, configure both unclassified-IPv4 packet initiation and ARP packet initiation.

To use IPv6 packets to trigger roaming in an IPv6 network, you must configure the ip subscriber initiator unclassified-ipv6 enable matching-user command on the target interface of roaming.

The following events might lead to failures in the process of roaming:

· The user IP address that the user belongs to is changed.

· The target interface is not configured with the same IPoE session initiation method as the interface before the roaming. For example, suppose interface A is configured with DHCP packet initiation. For roaming between interface A and interface B to succeed, interface B must be configured with DHCP packet initiation.

· The target interface and the current interface are not in the same roaming group.

· For dynamic individual users:

? A VPN instance is authorized to the roaming user. The target interface is bound to a different VPN instance.

? No VPN instance is authorized to the roaming user. The interface before roaming is bound to a VPN instance. The target interface is bound to a different VPN instance.

· For global static individual users:

? A VPN instance is authorized to the roaming user, and no VPN instance is specified in the static session. The target interface is bound to a VPN instance different from the authorized VPN instance.

? No VPN instance is authorized to the roaming user, and no VPN instance is specified in the static session. The interface before roaming is bound to a VPN instance. The target interface is bound to a different VPN instance.

If the roaming fails, the user must perform authentication again on the destination interface in order to come online.

For static individual users, the roaming function takes effect as follows:

· For interface-level static individual users, roaming is supported only when you configure IPoE static sessions in subinterface view by using the ip subscriber session static command without specifying a VLAN. In this case, only roaming across different VLANs of the subinterface is supported.

· For global static individual users, when you configure the ip subscriber session static command in system view, the following rules apply:

? If a user access interface is specified but no VLAN is specified, roaming across different VLANs of the interface is supported.

? If no user access interface is specified and a user comes online through a roaming-enabled interface, roaming across all roaming-enabled interfaces is supported.

Example: Configuring IPoE common Web authentication for DHCPv4 users

Network configuration

As shown in Figure 35, the host accesses the BRAS as a DHCP client though a Layer 2 device. It obtains configuration information from the DHCP server through the BRAS. The BRAS performs AAA for the host through the RADIUS server. A server installed with H3C IMC acts as the RADIUS server, the portal authentication server, and the portal Web server. The FTP server is an internal network server.

Example: Configuring IPoE common Web authentication for DHCPv6 users

Network configuration

As shown in Figure 48, Router A is a BRAS of a school. Configure the BRAS to provide users in the school with the following IPoE services:

· The host accesses the BRAS as a DHCP client though a Layer 2 device.

· The host obtains configuration information from the DHCP server through the BRAS.

· The BRAS performs AAA for the host through the RADIUS server. A server installed with H3C IMC acts as the RADIUS server, the portal authentication server, and the portal Web server.

· The FTP server is an internal network server.

· Limit the access rate to 5 Mbps for the user after passing Web authentication.

Figure 48 Network diagram

Procedure

1. Configure IP addresses and routes.

As shown in Figure 48, configure IP addresses for interfaces and make sure the BRAS and servers can reach each other at Layer 3. (Details not shown.)

2. Configure the DNS server.

Configure the DNS server properly, so that the server can parse the IPv6 URL corresponding to the Web authentication page http://www.h3c.web.com. (Details not shown.)

3. Configure the DHCP server:

# Create a DHCPv6 address pool named pool1 and enter its view.

<DHCP-server> system-view

[DHCP] ipv6 dhcp pool pool1

# Specify primary subnet 192::0/64 and DNS server address 8::8 for dynamic allocation in DHCPv6 address pool pool1.

[DHCP-dhcp6-pool-pool1] network 192::0/64

[DHCP-dhcp6-pool-pool1] dns-server 8::8

[DHCP-dhcp6-pool-pool1] quit

# Exclude IP address 192::1 from dynamic allocation in DHCPv6 address pool pool1.

[DHCP] ipv6 dhcp server forbidden-address 192::1

# Enable the DHCPv6 server on GigabitEthernet 3/1/1.

[DHCP] interface gigabitethernet 3/1/1

[DHCP-GigabitEthernet3/1/1] ipv6 dhcp select server

[DHCP-GigabitEthernet3/1/1] quit

# Configure a static route to specify the next hop of DHCPv6 replies destined to network segment 192::0 as the IP address of the interface connected to the DHCPv6 client, 4::2.

[DHCP] ipv6 route-static 192::0 64 4::2

4. Configure the BRAS:

a. Configure the DHCP relay agent:

# Create an IP address pool named pool1 for the DHCP relay agent.

<Device> system-view

[Device] ipv6 dhcp pool pool1

# Specify gateway address 192::1 in DHCP address pool pool1.

[Device-dhcp6-pool-pool1] gateway-list 192::1

# Disable RA message suppression on GigabitEthernet 3/1/2.

[Device–GigabitEthernet3/1/2] undo ipv6 nd ra halt

# Set the managed address configuration flag (M) to 1 in RA advertisements to be sent. Then, the host uses a DHCPv6 server to obtain IPv6 addresses.

[Device–GigabitEthernet3/1/2] ipv6 nd autoconfig managed-address-flag

# Set the other stateful configuration flag (O) to 1 in RA advertisements to be sent. Then, the host uses a DHCPv6 server to obtain configuration information other than IPv6 addresses.

[Device–GigabitEthernet3/1/2] ipv6 nd autoconfig other-flag

# Disable GigabitEthernet 3/1/2 from advertising the specified prefix in RA messages, preventing the endpoint from obtaining a temporary IPv6 address. In an IPv6 network, an endpoint might use a temporary IPv6 address for IPoE Web authentication, which will cause authentication failure.

Example: Configuring IPoE common Web authentication for dual-stack users

Network configuration

As shown in Figure 63, the host accesses the BRAS as a DHCP client though a Layer 2 device. It obtains configuration information from the DHCP server through the BRAS. The BRAS performs AAA for the host through the RADIUS server. A server installed with H3C IMC acts as the RADIUS server, the portal authentication server, and the portal Web server. The FTP server is an internal network server. Limit the access rate to 5 Mbps for the user after passing Web authentication.

Figure 63 Network diagram

Procedure

1. Configure IP addresses and routes.

As shown in Figure 63, configure IP addresses for interfaces and make sure the BRAS and servers can reach each other at Layer 3. (Details not shown.)

2. Configure the DNS server.

Configure the DNS server properly, so that the server can parse the IPv4 URL or IPv6 URL corresponding to the Web authentication page http://www.h3c.web.com according to the first protocol stack that comes online of the IPoE dual-stack user. (Details not shown.)

3. Configure the DHCP servers:

a. Configure the DHCPv4 address pool:

# Enable DHCP.

<DHCP> system-view

[DHCP] dhcp enable

# Create a DHCPv4 address pool named pool1 and enter its view.

[DHCP] dhcp server ip-pool pool1

# Specify primary subnet 192.168.0.0/24 for dynamic allocation in DHCPv4 address pool pool1.

[DHCP-dhcp-pool-pool1] network 192.168.0.0 24

# Specify gateway address 192.168.0.1 and DNS server address 8.8.8.8 in DHCPv4 address pool pool1.

Example: Configuring IPoE Layer 2 transparent MAC-trigger authentication

Network configuration

As shown in Figure 79, the host accesses the BRAS as a DHCP client though a Layer 2 device. It obtains configuration information from the DHCP server through the BRAS. A server installed with H3C IMC acts as the RADIUS server, the portal authentication server, the portal Web server, and the MAC binding server. The FTP server is an internal network server.

Example: Configuring IPoE Layer 3 transparent MAC-trigger authentication

Network configuration

As shown in Figure 97, the host accesses the BRAS as a DHCP client though a Layer 3 network. The BRAS also acts as the DHCP server. A server installed with H3C IMC acts as the RADIUS server, the portal authentication server, the portal Web server, and the MAC binding server. The FTP server is an internal network server.

Example: Configuring IPoE Layer 2 transparent MAC authentication

Network configuration

As shown in Figure 115, the host accesses the BRAS as a DHCP client though a Layer 2 device. It obtains configuration information from the DHCP server through the BRAS. The BRAS performs AAA for the host through the RADIUS server. A server installed with H3C IMC acts as the portal authentication server and the portal Web server. A RADIUS server that supports MAC binding acts as the authentication, authorization, and accounting server and performs MAC binding. The FTP server is an internal network server.

Example: Configuring IPoE Layer 3 transparent MAC authentication

Network configuration

As shown in Figure 122, the host accesses the BRAS as a DHCP client though a Layer 3 network. The BRAS also acts as the DHCP server. A server installed with H3C IMC acts as the portal authentication server and the portal Web server. A RADIUS server that supports MAC binding acts as the authentication, authorization, and accounting server and performs MAC binding. The FTP server is an internal network server.

Network configuration

As shown in Figure 129, the host accesses the BRAS as a DHCP client though a Layer 2 device. It obtains configuration information from the DHCP server through the BRAS. The BRAS performs AAA for the host through the RADIUS server. A server installed with H3C IMC acts as the portal authentication server and the portal Web server. A RADIUS server that supports MAC binding acts as the authentication, authorization, and accounting server and performs MAC binding. The FTP server is an internal network server. Limit the access rate to 5 Mbps for the user after passing Web authentication.

Example: Configuring a roaming user

Network configuration

As shown in Figure 152, the host accesses the BRAS as a roaming user. The host obtains an IP address from the DHCP server. The BRAS performs AAA for the host through the RADIUS server.

Figure 152 Network diagram

Procedure

NOTE:

In this example, when a user obtains an IP address through DHCP, the DHCP packets do not carry Option 60.

1. Configure the RADIUS server: (This section uses the Linux Free RADIUS server as an example.)

# Add BRAS IP address 4.4.4.2 and secret radius to the clients.conf file.

client 4.4.4.2/32 {

ipaddr = 4.4.4.2

netmask=32

secret=radius

}

# Add the username and password to the users user information file. The username is the host MAC address and the password is radius.

000c29a6b656 Cleartext-Password :="radius"

2. Configure the DHCP server:

a. Configure the DHCPv4 address pool:

# Enable DHCP.

<DHCP-server> system-view

[DHCP-server] dhcp enable

# Create a DHCPv4 address pool named pool1 and enter its view.

[DHCP-server] dhcp server ip-pool pool1

# Specify the subnet 3.3.3.0/24 for dynamic allocation in the pool.

[DHCP-server-dhcp-pool-pool1] network 3.3.3.0 24

# Specify gateway address 3.3.3.1 in the address pool.

[DHCP-server-dhcp-pool-pool1] gateway-list 3.3.3.1

# Exclude IP address 3.3.3.1 from dynamic allocation in the pool.

[DHCP-server-dhcp-pool-pool1] forbidden-ip 3.3.3.1

Troubleshooting IPoE

DHCP clients failed to come online

Symptom

DHCP clients cannot come online, although network connections and interface IPoE configurations are correct.

Solution

To solve the problem:

1. Use debug commands or a packet analyzer to check DHCP packets from the DHCP client.

By default, DHCPv4 and DHCPv6 clients use ISP domains specified in Option 60 and Option 16/Option 17, respectively.

2. If the DHCPv4 packet carries Option 60 or the DHCPv6 packet carries Option 16/Option 17, verify that the ISP domain in the option exists on the BRAS.

3. If the DHCP packet does not carry Option 60 or Option 16/Option 17, verify that the ISP domain specified on the interface exists on the BRAS.

4. If the problem persists, contact H3C Support.
