portal auth-network
Syntax
portal auth-network network-address { mask-length | mask }
undo portal auth-network { network-address | all }
View
Interface view
Default level
2: System level
Parameters
network-address: IP address of the authentication subnet.
mask-length: Length of the subnet mask, in the range of 0 to 32.
mask: Subnet mask, in dotted decimal notation.
all: Specifies all authentication subnets.
Description
Use the portal auth-network command to configure a portal authentication subnet on an interface. You can use this command to configure multiple portal authentication subnets on an interface. Then, only HTTP packets from the subnets can trigger portal authentication on the interface. If an unauthenticated user is not on any authentication subnet, the access device discards all the user’s packets that do not match any portal-free rule.
Use the undo portal auth-network command to remove a specific portal authentication subnet or all portal authentication subnets.
By default, the portal authentication subnet is 0.0.0.0/0, meaning that users in all subnets must pass portal authentication.
This command is only applicable for cross-subnet authentication (layer3). The portal authentication subnet for re-DHCP authentication (redhcp) is the one determined by the private IP address of the interface connecting the users.
You can configure multiple authentication subnets by executing the portal auth-network command repeatedly.
Examples
# Configure a portal authentication source subnet of 10.10.10.0/24 on interface VLAN-interface 2 to allow users from subnet 10.10.10.0/24 to trigger portal authentication.
<Sysname> system-view

Description
Use the portal domain command to specify an authentication domain for an interface. Then, the switch will use the authentication domain for authentication, authorization and accounting (AAA) of the portal users on the interface.
Use the undo portal domain command to restore the default.
By default, no authentication domain is specified for an interface.
Related commands: display portal interface.
Examples
# Configure the authentication domain to be used for portal users on VLAN-interface 100 as my-domain.

vlan vlan-id: Specifies a source VLAN ID.
all: Specifies all portal-free rules.
Description
Use the portal free-rule command to configure a portal-free rule and specify the source filtering condition, destination filtering condition, or both.
Use the undo portal free-rule command to remove a specific portal-free rule or all portal-free rules.
If you specify both a VLAN and an interface in a portal-free rule, the interface must belong to the VLAN. Otherwise, the rule does not take effect.
You cannot configure a portal-free rule to have the same filtering criteria as that of an existing one. When attempted, the system prompts that the rule already exists.
No matter whether portal authentication is enabled on an interface, you can only add or remove a portal-free rule, rather than modifying it.
A Layer 2 interface in an aggregation group cannot be specified as the source interface of a portal-free rule, and the source interface of a portal-free rule cannot be added to an aggregation group.
Related commands: display portal free-rule.

Parameters
profile-name: Name of the profile that defines the binding relationship between VLANs and NAS IDs, a case-insensitive string of 1 to 16 characters. The profile can be configured by using the aaa nas-id profile command. For more information about this command, see the chapter “AAA configuration commands.”
Description
Use the portal nas-id-profile command to specify a NAS ID profile for the interface.
Use the undo portal nas-id-profile command to cancel the configuration.
By default, an interface is not specified with any NAS ID profile.
If an interface is specified with a NAS ID profile, the interface will prefer to use the binding defined in the profile. If no NAS ID profile is specified for an interface or no matching binding is found in the specified profile, the switch name will be used as the interface NAS-ID.

Parameters
url-string: Automatic redirection URL for authenticated portal users, a string of 1 to 127 characters. It must start with http:// or https:// and must be a fully qualified URL.
wait-time period: Time that the device must wait before redirecting a user passing portal authentication to the automatic redirection URL. It ranges from 1 to 90 and defaults to 5, in seconds. The switch does not support the wait-time period option.
Description
Use the portal redirect-url command to specify an automatic redirection URL for authenticated portal users.
Use the undo portal redirect-url command to restore the default.
By default, a user authenticated is redirected to the URL the user entered in the address bar before portal authentication.
With Layer 3 portal authentication, this feature requires the cooperation of an iMC server that supports the page auto-redirection function.

Parameters
server-name: Name of the portal server, a case-sensitive string of 1 to 32 characters.
ip-address: IP address of the portal server.
key-string: Shared key for communication with the portal server, a case-sensitive string of 1 to 16 characters. Portal packets exchanged between the access device (the switch) and the portal server carry an authenticator, which is generated with the shared key. The receiver uses the authenticator to check the correctness of the received portal packets.
port-id: Destination port number used when the switch sends an unsolicited message to the portal server, in the range of 1 to 65534. The default is 50100.
url-string: Uniform resource locator (URL) to which HTTP packets are to be redirected. The default URL is in the http://ip-address format, where ip-address is the IP address of the portal server. You can also specify the domain name of the portal server, in which case you need to use the portal free-rule command to configure the IP address of the DNS server as a portal authentication-free destination IP address.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the portal server belongs. vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the portal server is on the public network, do not specify this option.
Description
Use the portal server command to configure a portal server for Layer 3 portal authentication.
Use the undo portal server command to remove a portal server, restore the default destination port and default URL address, or delete the shared key or the VPN instance configuration.
By default, no portal server is configured for Layer 3 portal authentication.
If the specified portal server exists and no user is on the interfaces referencing the portal server, using the undo portal server server-name command removes the specified portal server, and if keyword port or url is also provided, the command will restore the destination port number or URL address to the default.
The configured portal server and its parameters can be removed or modified only when the portal server is not referenced by an interface. To remove or modify the settings of a portal server that has been referenced by an interface, you must first remove the portal configuration on the interface by using the undo portal command.
Related commands: display portal server.

View

Default level
2: System level
Parameters
server-name: Name of a portal server, a case-sensitive string of 1 to 32 characters. The specified portal server must have existed.
server-detect method { http | portal-heartbeat }: Specifies the portal server detection method. Two detection methods are available:
· http: Probes HTTP connections. In this method, the switch (the access device) periodically sends TCP connection requests to the HTTP service port of the portal servers enabled on its interfaces. If the TCP connection with a portal server can be established, the access device considers that the HTTP service of the portal server is open and the portal server is reachable—the detection succeeds. If the TCP connection cannot be established, the access device considers that the detection fails—the portal server is unreachable. If a portal server does not support the portal server heartbeat function, you can configure the switch to use the HTTP probe method to detect the reachability of the portal server.
· portal-heartbeat: Probes portal heartbeat packets. Portal servers periodically send portal heartbeat packets to the access devices. If the access device receives a portal heartbeat packet from a portal server within the specified interval, the access device considers that the probe succeeds and the portal server is reachable; otherwise, it considers that the probe fails and the portal server is unreachable. This method is effective to only portal servers that support the portal heartbeat function. Currently, only the iMC portal server supports this function. To implement detection with this method, you also need to configure the portal server heartbeat function on the iMC portal server and make sure that the server heartbeat interval configured on the portal server is shorter than or equal to the probe interval configured on the switch.
action { log | permit-all | trap }: Specifies the actions to be taken when the status of a portal server changes. The following actions are available:
· log: Specifies the action as sending a log message. When the status (reachable/unreachable) of a portal server changes, the access device sends a log message. The log message contains the portal server name and the current state and original state of the portal server.
· permit-all: Specifies the action as disabling portal authentication—enabling portal authentication bypass. When the access device detects that a portal server is unreachable, it disables portal authentication on the interface referencing the portal server, allowing all portal users on this interface to access network resources. When the access device receives the portal server heartbeat packets or authentication packets (such as login requests and logout requests), it re-enables the portal authentication function.
· trap: Specifies the action as sending a trap message. When the status (reachable/unreachable) of a portal server changes, the access device sends a trap message to the network management server (NMS). Trap message contains the portal server name and the current state of the portal server.
interval interval: Interval at which probe attempts are made. The interval argument ranges from 20 to 600 and defaults to 20, in seconds.
retry retries: Maximum number of probe attempts. The retries argument ranges from 1 to 5 and defaults to 3. If the number of consecutive, failed probes reaches this value, the access device considers that the portal server is unreachable.
Description
Use the portal server server-detect command to configure portal server detection, including the detection method, action, probe interval, and maximum number of probe attempts. With this function configured, the switch checks the status of the specified server periodically and takes the specified actions when the server status changes.
Use the undo portal server server-detect command to cancel the detection of the specified portal server.
By default, the portal server detection function is not configured.
You can specify one or more detection methods and the actions to be taken.
If both detection methods are specified, a portal server will be regarded as unreachable as long as one detection method fails, and an unreachable portal server will be regarded as recovered only when both detection methods succeed.
If multiple actions are specified, the system will execute all the specified actions when the status of a portal server changes.
Deleting a portal server on the switch will delete the detection function for the portal server.
If you configure the detection function for a portal server for multiple times, the last configuration will take effect. If you do not specify an optional parameter, the default setting of the parameter will be used.
The portal server detection function takes effect only when the portal server is referenced on an interface.
Authentication-related packets from a portal server, such as logon requests and logoff requests, have the same effect as the portal heartbeat packets for the portal server detection function.
Related command: display portal server.
Examples
# Configure the switch to detect portal server pts:
· Specifying both the HTTP probe and portal heartbeat probe methods
· Setting the probe interval to 600 seconds
· Specifying the switch to send a server unreachable trap message, send a log message and disable portal authentication to permit unauthenticated portal users, if two consecutive probes fail.

Default level
2: System level
Parameters
server-name: Name of a portal server, a case-sensitive string of 1 to 32 characters. The specified portal server must have existed.
user-sync: Enables the portal user synchronization function.
interval interval: Specifies the interval at which the switch checks the user synchronization packets. The interval argument ranges from 60 to 3600 and defaults to 300, in seconds.
retry retries: Specifies the maximum number of consecutive failed checks. The retries argument ranges from 1 to 5 and defaults to 4. If the switch finds that one of its users does not exist in the user synchronization packets from the portal server within N consecutive probe intervals (N = retries), it considers that the user does not exist on the portal server and logs the user off.
Description
Use the portal server user-sync command to configure portal user information synchronization with a specific portal server. With this function configured, the switch periodically checks and responds to the user synchronization packet received from the specified portal server, so as to keep the consistency of the online user information on the switch and the portal server.
Use the undo portal server user-sync command to cancel the portal user information synchronization configuration with the specified portal server.
By default, the portal user synchronization function is not configured.
The user information synchronization function requires that a portal server supports the portal user heartbeat function (currently only the iMC portal server supports portal user heartbeat). To implement the portal user synchronization function, you also need to configure the user heartbeat function on the portal server and make sure that the user heartbeat interval configured on the portal server is shorter than or equal to the synchronization probe interval configured on the switch.
Deleting a portal server on the switch will delete the portal user synchronization configuration with the portal server.
If you configure the user synchronization function for a portal server for multiple times, the last configuration will take effect. If you do not specify an optional parameter, the default setting of the parameter will be used.
For redundant user information on the switch—information of the users considered as nonexistent on the portal server, the switch will delete the information during the (N+1)th probe interval, where N equals to the value of retries configured in the portal server user-sync command.
Examples
# Configure the switch to synchronize portal user information with portal server pts:
· Setting the synchronization probe interval to 600 seconds
· Specifying the switch to log off users if information of the users does not exist in the user synchronization packets sent from the server in two consecutive probe intervals.
