·     The VLAN IDs are in the range of 1 to 4094.

·     The VLANs already exist.

Usage guidelines

Non-default vSystems do not support this command.

You cannot add a member to the system-defined security zone Local. You can add members to the other system-defined security zones.

To add multiple Layer 2 Ethernet interface-VLAN combinations to a security zone, execute this command multiple times.

A Layer 2 interface-VLAN combination can belong to only one security zone. To move a Layer 2 interface-VLAN combination from one security zone to another security zone, perform the following tasks:

1.     Use the undo import interface vlan command to remove the combination from the current security zone.

2.     Use the import interface vlan command to add the combination to the new security zone.

Examples

Parameters

ip-address: Specifies an IPv4 subnet by its subnet address or a host address on the subnet.

mask-length: Specifies the mask length in the range of 0 to 32.

mask: Specifies the subnet mask in dotted decimal notation.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the subnet belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive string of 1 to 31 characters. If the subnet resides on the public network, do not specify this option. As a best practice, specify an existing VPN instance. If you specify a non-existent VPN instance, this command will be successfully executed but will not take effect. Additionally, this command will get lost after the device restarts.

Usage guidelines

You cannot add a member to the system-defined security zone Local. You can add members to the other system-defined security zones.

To add multiple IPv4 subnets to a security zone, execute this command multiple times.

A subnet can be added to only one security zone.

If one subnet includes another subnet, the system identifies them as different subnets. You can add them to the same security zone or different security zones. If you add them to different security zones, packets that match both subnets are identified as packets of the security zone to which the smaller subnet belongs. For example, you can assign 1.1.1.1/24 and 1.1.2.2/16 to different security zones. A packet with the IP address 1.1.1.3 is identified as a packet of the security zone to which 1.1.1.1/24 belongs.

For a dynamic routing protocol to operate correctly, add the multicast and broadcast addresses used by the protocol to security zones as needed.

Examples

# Add the 192.168.1.0/24 subnet to security zone a.

<Sysname> system-view

[Sysname] security-zone name a

[Sysname-security-zone-a] import ip 192.168.1.0 24

# Add the subnet that is identified by the address 192.168.2.1 and mask 255.255.255.0 to security zone a.

<Sysname> system-view

[Sysname] security-zone name a

To add multiple IPv6 subnets to a security zone, execute this command multiple times.

A subnet can be added to only one security zone.

If one subnet includes another subnet, the system identifies them as different subnets. You can add them to the same security zone or different security zones. If you add them to different security zones, packets that match both subnets are identified as packets of the security zone to which the smaller subnet belongs. For example, you can assign 1:1:1::0/48 and 1:1:1::0/32 to different security zones. A packet with the address 1:1:1::2 is identified as a packet of the security zone to which 1:1:1::0/48 belongs.

Examples

# Add IPv6 subnet 1001:1002::0/32 (on the public network) to security zone a.

<Sysname> system-view

Parameters

name zone-name: Specifies the security zone name, a case-insensitive string of 1 to 31 characters. It cannot be any. To include a backward slash (\) or quotation mark (") in the security zone name, you must use the escape character (\).

Usage guidelines

The device provides the following system-defined security zones: Local, Trust, DMZ, Management, and Untrust. The system creates these security zones automatically when one of following events occurs:

·     The first command for creating a security zone is executed.

·     The first command related to creating an interzone policy is executed.

System-defined security zones cannot be deleted.

You can use this command multiple times to create multiple security zones.

Deleting a security zone also deletes the following items:

·     All zone pairs that use the security zone as the source or destination security zone.

·     All interzone policy applications on the zone pairs.

Parameters

source source-zone-name: Specifies the name of the source security zone, a case-insensitive string of 1 to 31 characters. This security zone must already exist.

destination destination-zone-name: Specifies the name of the destination security zone, a case-insensitive string of 1 to 31 characters. This security zone must already exist.

any: Specifies any security zone.

Usage guidelines

Non-default vSystems do not support this command.

A zone pair has a source security zone and a destination security zone. The device examines received first data packets and uses zone pairs to identify data flows. You can apply interzone policies to zone pairs so the device processes data flows based on interzone policies.

You can use the zone-pair security source any destination any command to define the any-to-any zone pair. This zone pair matches all packets from one security zone to another security zone.

A zone pair between specific security zones has a higher priority than the any-to-any zone pair.

A packet between the Management and Local zones matches only zone pairs of the two zones. It does not match the any-to-any zone pair.

Deleting a zone pair deletes all interzone policy applications on the zone pair.

Examples

# Create a zone pair with the source security zone Trust and destination zone Untrust.

<Sysname> system-view

[Sysname] zone-pair security source trust destination untrust

[Sysname-zone-pair-security-Trust-Untrust]

Usage guidelines

Non-default vSystems do not support this command.

In scenarios where server load balancing is deployed, configure this command to enable the device to filter packets from external networks to internal servers by virtual service IP address. By default, filtering based on virtual service IP address is disabled. Before matching each of the packets against ACLs, the device translates the destination IP address (the virtual service IP address) to the real server IP address. For more information about packet filtering, see ACL configuration in ACL and QoS Configuration Guide.

Examples

# Configure an IPv4 advanced ACL to permit packets destined for virtual server IP address 10.10.10.10. Configure a zone pair from Untrust to DMZ, apply the ACL to the zone pair, and enable filtering based on virtual service IP address.
