Configures the topology group.
A topology group is not configured.
Global configuration mode
Each topology group contains a master VLAN and can contain one or more member VLANs and VLAN groups. You must configure the master VLAN and member VLANs or member VLAN groups before you configure the topology group.
You can configure up to 30 topology groups. Each group can control up to 4096 VLANs. A VLAN cannot be controlled by more than one topology group. The topology group must contain a master VLAN and can also contain individual member VLANs, VLAN groups, or a combination of individual member VLANs and VLAN groups.
The no form of the command removes the topology group.
The following example configures the topology group with ID 2 and adds master VLAN and member VLANs.
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-vlan 4 device(config-topo-group-2)# member-vlan 5
