Before adding a member VLAN, you should have created a topology group and configured the master VLAN for that group. The VLAN should not be part of any other topology group. All control ports of master VLAN must also be configured for the member VLAN.
device# configure terminal device(config)#
device(config)# topology-group 1 device(conf-topo-group-1)#
device(conf-topo-group-1)# master-vlan 100
device(conf-topo-group-1)# member-vlan add 200-201
Note
The member-vlan remove command removes an existing member VLAN from the topology group.device(conf-topo-group-1)# member-vlan remove 200
