For Switch A, packets from SwitchB and Switch C are without VLAN tag, so that Switch A needs not to consider theVLAN configurations of the lower layer switches.z VLAN 5 on Switch B is an isolate-user-VLAN which includes the uplink portEthernet 1/0/1 and two secondary VLANs: VLAN 2 and VLAN 3. VLAN 3 includesport Ethernet 1/0/2, and VLAN 2 includes port Ethernet 1/0/5.z VLAN 6 on Switch C is an isolate-user-VLAN which includes the uplink portEthernet 1/0/1 and two secondary VLANs: VLAN 3 and VLAN 4. VLAN 3 includesport Ethernet 1/0/3, and VLAN 4 includes port Ethernet 1/0/4.
