Chapter 41 Configuring Ethernet OAM, CFM, and E-LMI
Ethernet CFM and Ethernet OAM Interaction
Switch(config-if)# ethernet uni id 2004-20
Switch(config-if)# ethernet oam remote-loopback supported
Switch(config-if)# ethernet oam
Switch(config-if)# service instance 10 ethernet BLUE
Switch(config-if-srv)# ethernet lmi ce-vlan map 10
Switch(config-if-srv)# exit
Provider-edge switch 2 (PE2) configuration:
Switch# config t
Switch(config)# interface gigabitethernet1/20
Switch(config-if)# switchport mode trunk
Switch(config-if)# ethernet cfm mip level 7
Switch(config-if)# ethernet cfm mep level 4 mpid 101 vlan 10
Switch(config-if)# ethernet uni id 2004-20
Switch(config-if)# ethernet oam remote-loopback supported
Switch(config-if)# ethernet oam
Switch(config-if)# service instance 10 ethernet BLUE
Switch(config-if-srv)# ethernet lmi ce-vlan map 10
Switch(config-if-srv)# exit
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.
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 Gi0/1 27 blue
Switch PE2:
Switch# show ethernet cfm maintenance points remote

This example shows the outputs when you start remote loopback on CE1 (or PE1). The port state on the
remote PE switch shows as Tes t 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]
