Balaji,
The output of this command on switch-A, corresponds also to
switch-B
Switch-A#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Fa0/2 desirable 802.1q trunking 1
Port Vlans allowed on trunk
Fa0/2 1-4094
Port Vlans allowed and active in management domain
Fa0/2 1-2,6-7
Port Vlans in spanning tree forwarding state and not pruned
Fa0/2 1-2,6-7
Thanks,
Mesut
