Isolate-User-VLAN Configuration Example
Network requirements
z Connect Device A to downstream devices Device B and Device C;
z Configure VLAN 5 on Device B as an isolate-user-VLAN, assign the uplink port GigabitEthernet
1/0/5 to VLAN 5, and associate VLAN 5 with secondary VLANs VLAN 2 and VLAN 3. Assign
GigabitEthernet 1/0/2 to VLAN 2 and GigabitEthernet 1/0/1 to VLAN 3.
z Configure VLAN 6 on Device C as an isolate-user-VLAN, assign the uplink port GigabitEthernet
1/0/5 to VLAN 6, and associate VLAN 6 with secondary VLANs VLAN 3 and VLAN 4. Assign
GigabitEthernet 1/0/3 to VLAN 3 and GigabitEthernet 1/0/4 to VLAN 4.
z For Device A, Device B only has VLAN 5 and Device C only has VLAN 6.
