Examples: Configuring the SP Edge and Customer Switches

This example shows how to configure the SP edge switch 1 and edge switch 2. VLANs 17, 18, 19, and 20 are the access VLANs, Fast Ethernet interfaces 1 and 2 are point-to-point tunnel ports with PAgP and UDLD enabled, the drop threshold is 1000, and Fast Ethernet interface 3 is a trunk port.

SP edge switch 1 configuration:

Switch(config)# interface gigabitethernet1/0/1

Switch(config-if)#switchport access vlan 17

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)#l2protocol-tunnel drop-threshold point-to-point pagp 1000

Switch(config-if)# exit

Switch(config)# interface gigabitethernet1/0/2

Switch(config-if)#switchport access vlan 18

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)#l2protocol-tunnel drop-threshold point-to-point pagp 1000

Switch(config-if)# exit

Switch(config)# interface gigabitethernet1/0/3

Switch(config-if)#switchport trunk encapsulation isl

Switch(config-if)#switchport mode trunk

SP edge switch 2 configuration:

Switch(config)# interface gigabitethernet1/0/1

Switch(config-if)#switchport access vlan 19

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)#l2protocol-tunnel drop-threshold point-to-point pagp 1000

Switch(config-if)# exit

Switch(config)# interface gigabitethernet1/0/2

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)#l2protocol-tunnel drop-threshold point-to-point pagp 1000

Switch(config-if)# exit

Switch(config)# interface gigabitethernet1/0/3

Switch(config-if)#switchport trunk encapsulation isl

Switch(config-if)# switchport mode trunk

This example shows how to configure the customer switch at Site 1. Fast Ethernet interfaces 1, 2, 3, and 4 are set for IEEE 802.1Q trunking, UDLD is enabled, EtherChannel group 1 is enabled, and the port channel is shut down and then enabled to activate the EtherChannel configuration.

Switch(config)# interface gigabitethernet1/0/1

Switch(config-if)#switchport trunk encapsulation dot1q

Switch(config-if)#switchport mode trunk

Switch(config-if)# udld enable

Switch(config-if)#channel-group 1 mode desirable

Switch(config-if)# exit

Switch(config)# interface gigabitethernet1/0/2

Switch(config-if)#switchport trunk encapsulation dot1q

Switch(config-if)#switchport mode trunk

Switch(config-if)# udld enable

Switch(config-if)#channel-group 1 mode desirable

Switch(config-if)# exit

Switch(config)# interface gigabitethernet1/0/3

Switch(config-if)#switchport trunk encapsulation dot1q
