Configuring a Topology Group

You can configure a topology group with a master VLAN. You can add member VLANs and VLAN groups to the master VLAN.
A topology group can have only one master VLAN. The master VLAN must be already configured before it is added to the topology group.

Once you add a VLAN or VLAN group as a member of a topology group, all the Layer 2 protocol configuration information for the VLAN or VLAN group is deleted and uses the Layer 2 protocol settings of the master VLAN instead.

If you remove a member VLAN or VLAN group from a topology group, you will need to reconfigure the Layer 2 protocol information in the VLAN or VLAN group.

  1. Enter global configuration mode.
    device# configure terminal
  2. Configure a topology group.
    device(config)# topology-group 2
  3. Add a master VLAN to the topology group.
    device(config-topo-group-2)# master-vlan 2
  4. Add a member VLAN to the topology group.
    device(config-topo-group-2)# member-vlan 3
  5. Add a member VLAN group to the topology group.
    device(config-topo-group-2)# member-group 2

The following example shows how to configure a topology group and add member VLANs and VLAN groups to the topology group.

device# configure terminal
device(config)# topology-group 2
device(config-topo-group-2)# master-vlan 2
device(config-topo-group-2)# member-vlan 3
device(config-topo-group-2)# member-group 2
