Chapter 75 Configuring Ethernet OAM and CFM
Ethernet CFM and Ethernet OAM Interaction
Switch(config-if)# ethernet oam
Customer-edge switch 2 (CE2) configuration:
Switch# config terminal
Switch(config)# interface GigabitEthernet1/1
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 output examples show provider-edge switch port status of the configuration. Port status shows as
UP at both switches.
Switch PE1:
Switch# show ethernet cfm maintenance points remote
MPID Level Mac Address Vlan PortState InGressPort Age(sec) Service ID
101 * 4 0015.633f.6900 10 UP Gi1/1 27 blue
Switch PE2:

This example shows the output when you start remote loopback on CE1 (or PE1). The port state on the
remote PE switch shows as Te st and the remote CE switch enters into error-disable mode.
Switch# ethernet oam remote-loopback start interface gigabitethernet 1/1
it 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]
Switch PE1:
Switch# show ethernet cfm maintenance points remote
MPID Level Mac Address Vlan PortState InGressPort Age(sec) Service ID
101 * 4 0015.633f.6900 10 UP Gi1/1 27 blue
Switch PE2:
Switch# show ethernet cfm maintenance points remote
MPID Level Mac Address Vlan PortState InGressPort Age(sec) Service ID
100 * 4 0012.00a3.3780 10 TEST Gi1/1 8 blue
Total Remote MEPs: 1
In addition, if you shut down the CE1 interface that connects to PE1, the remote PE2 port shows a
PortState of Down.
