Chapter 15 Configuring Ethernet OAM, CFM, and E-LMI
Configuration Examples
Router(config-if-srv)# exit
Customer-edge device 2 (CE2) configuration:
Router# config t
Router(config)# interface gigabitethernet1/0/1
Router(config-if)# switchport trunk allowed vlan 10
Router(config-if)# switchport mode trunk
Router(config-if)# ethernet oam remote-loopback supported
Router(config-if)# ethernet oam
Router(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.
PE1:

This example shows the outputs 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 goes into error-disable mode.
Router# 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]
PE1:
Router# show ethernet cfm maintenance points remote
MPID Level Mac Address Vlan PortState InGressPort Age(sec) Service ID
101 * 4 0015.633f.6900 10 UP Gi1/1/1 27 blue
PE2:
Router# show ethernet cfm maintenance points remote
MPID Level Mac Address Vlan PortState InGressPort Age(sec) Service ID
100 * 4 0012.00a3.3780 10 TEST Gi1/1/1 8 blue
Total Remote MEPs: 1
In addition, if you shut down the CE1 interface that connects to PE1, the remote PE2 port will show a
PortState of Down.
CFM and ELMI Sample Configuration: Example
The following sample configuration uses CFM and ELMI with three inward facing MEPs, two MIPs,
and three maintenance domains.
Note This section provides partial configurations intended to demonstrate a specific feature.
