1 Default active static 1-10 1-10 -- 0:0:7
10 VLAN0010 active static 1-3 2,3 -- 0:1:1
20 VLAN0020 active static 4 4 -- 0:1:1
Use the show interface port port-id switchport command to check whether interface VLAN
is correctly configured.
Take Switch B for example.
SwitchB#show interface port 2 switchport
Port:2
Administrative Mode: access

Use the show switchport protect command to check whether interface protection is correctly
configured.
SwitchB#show switchport protect

Check whether PC 1 can ping PC 5, PC 2 can ping PC 5, and PC 3 can ping PC 4 successfully.
Check whether the VLAN allowed to pass on the Trunk interface is correct.
If PC 1 can ping PC 5 successfully, VLAN 10 communicates properly.
If PC 2 can ping PC 5 successfully, VLAN 10 communicates properly.
If PC 3 fails ping PC 4, VLAN 20 fails to communicate.
By pinging PC 2 through PC 1, check whether interface protection is correctly configured.
