Verifying the Ethernet CFM Configuration for Single-Tagged Packets
Use the following commands to verify Ethernet CFM configured for single-tagged packets:
• show ethernet cfm domain
• show ethernet cfm maintenance-points local
• show ethernet cfm maintenance-points remote
• show ethernet cfm error configuration
Use the show ethernet cfm domain command to display the maintenance point domains configured in
the network. In the following example, customer, enterprise, and carrier maintenance point domains are
configured:
Router#show ethernet cfm domain
Domain Name: customer
Level: 7
Total Services: 1
Services:

Use the show ethernet cfm maintenance-points local command to view the local MEPs. The following
is a sample output of the show ethernet cfm maintenance-points local command:
Router#show ethernet cfm maintenance-points local
