- Switch1(config-if)# switchport trunk encapsulation dot1q
- Switch1(config-if)# switchport mode trunk
- Switch1(config-if)# switchport trunk allowed vlan 100,200
- —
- Switch2(config)# interface g1/0/20
- Switch2(config-if)# switchport trunk encapsulation dot1q
- Switch2(config-if)# switchport mode trunk
- Switch2(config-if)# switchport trunk allowed vlan 100,200
