Switch(config)# interface gigabitEthernet 1/1/12
Switch(config-if)# switchport access vlan 20
Switch(config-if)# switchport mode dot1q-tunnel
Switch(config-if)# l2protocol-tunnel point-to-point pagp
Switch(config-if)# l2protocol-tunnel point-to-point udld

Switch(config-if)# switchport mode trunk
This example shows how to configure the customer switch at Site 1. Gigabit Ethernet interfaces 1/1, 1/2,
1/3, and 1/4 are set for 802.1Q trunking, UDLD is enabled, EtherChannel group 1 is enabled, and the
port channel is shut down and then enabled to activate EtherChannel configuration. See also Figure 30-8.
