Customer-edge switch 2 (CE2) configuration:
Switch# config t
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# port-type nni
Switch(config-if)# switchport trunk allowed vlan 10
Switch(config-if)# switchport mode trunk
Switch(config-if)# ethernet oam remote-loopback supported
Switch(config-if)# ethernet oam
Switch(config-if)# exit
These are examples of the output showing provider-edge switch port status of the configuration. Port
status shows as UP at both switches.

This example shows the outputs when you start remote loopback on CE1 (or PE1). The port state on the
remote PE switch shows as Test and the remote CE switch goes into error-disable mode.
Switch# ethernet oam remote-loopback start interface gigabitEthernet 0/1
This is a intrusive loopback.
Therefore, while you test Ethernet OAM MAC connectivity,
you will be unable to pass traffic across that link.
Proceed with Remote Loopback? [confirm]

In addition, if you shut down the CE1 interface that connects to PE1, the remote PE2 port will show a
PortState of Down.
