After associating an isolate-user-VLAN with the specified secondary VLANs, you cannot add/remove a 

access port to/from each involved VLAN or remove each involved VLAN. To do that, you must cancel 

the association first.

Configure VLAN 5 on Device B as an isolate-user-VLAN, assign the uplink port GigabitEthernet 

2/0/5 to VLAN 5, and associate VLAN 5 with secondary VLANs VLAN 2 and VLAN 3. Assign 

GigabitEthernet 2/0/2 to VLAN 2 and GigabitEthernet 2/0/1 to VLAN 3. 

z 

Configure VLAN 6 on Device C as an isolate-user-VLAN, assign the uplink port GigabitEthernet 

2/0/5 to VLAN 6, and associate VLAN 6 with secondary VLANs VLAN 3 and VLAN 4. Assign 

GigabitEthernet 2/0/3 to VLAN 3 and GigabitEthernet 2/0/4 to VLAN 4. 

z 

For Device A, Device B only has VLAN 5 and Device C only has VLAN 6.
