Network requirements
Switch A is connected to Switch B and Switch C in the downstream.
1 On Switch B
VLAN 5 is an isolate-user-VLAN, including an upstream port (Ethernet2/1/1 port)
and two Secondary VLANs, VLAN2 and VLAN3. VLAN 2 includes Ethernet2/1/2
port and VLAN 3 includes Ethernet2/1/3 port.
2 On Switch C
VLAN 6 is an isolate-user-VLAN including an upstream port (Ethernet2/1/1 port)
and two Secondary VLANs: VLAN3 and VLAN4. VLAN3 includes Ethernet2/1/3
port and VLAN4 includes Ethernet2/1/4 port.
Seen from the Switch A, either Switch B or Switch C carries one VLAN, VLAN 5
and VLAN 6 respectively.
