Displaying information about VLAN groups
To display VLAN group configuration information, use the show vlan-group command.
device# show vlan-group
vlan-group 1 vlan 2 to 20
tagged ethe 1/1 to 1/2
!
vlan-group 2 vlan 21 to 40
tagged ethe 1/1 to 1/2
!
Syntax: show vlan-group [group-id]
The group-id specifies a VLAN group. If you do not use this parameter, the configuration information
for all the configured VLAN groups is displayed.
Configuring a virtual routing interface group
A virtual routing interface group allows you to associate the same IP subnet interface with multiple
port-based VLANs. For example, if you associate a virtual routing interface group with a VLAN
group, all the VLANs in the group have the IP interface of the virtual routing interface group.
Configuration notes and feature limitations for virtual routing interface group
When you configure a virtual routing interface group, all members of the group have the same IP
subnet address. This feature is useful in collocation environments where the device has many IP
addresses and you want to conserve the IP address space.
The group-router-interface command creates router interfaces for each VLAN in the VLAN group
by using the VLAN IDs of each of the VLANs as the corresponding virtual interface number.
Therefore, if a VLAN group contains VLAN IDs greater than the maximum virtual interface number
allowed, the group-router-interface command will be rejected.
CLI syntax for virtual routing interface group
To configure a virtual routing interface group, enter commands such as the following.
device(config)# vlan-group 1
device(config-vlan-group-1)# group-router-interface
device(config-vlan-group-1)# exit
device(config)# interface group-ve 1
device(config-vif-group-1)# ip address 10.10.10.1/24
These commands enable VLAN group 1 to have a group virtual routing interface, then configure virtual
routing interface group 1. The software always associates a virtual routing interface group only with
the VLAN group that has the same ID. In this example, the VLAN group ID is 1, so the corresponding
virtual routing interface group also must have ID 1.
Syntax: group-router-interface
Syntax: interface group-ve num
Syntax: [no] ip address ip-addr ip-mask [ secondary ]
or
Syntax: [no] ip address ip-addr/mask-bits [ secondary ]
The router-interface-group command enables a VLAN group to use a virtual routing interface group.
Enter this command at the configuration level for the VLAN group. This command configures the
