Configuring CFM over EFP Interface with Cross Connect—Port Channel-Based Cross Connect
Tunnel
This section describes how to configure CFM over EFP Interface with Port Channel-Based cross connect
Tunnel.

Verification
Use the following commands to verify a configuration:
• Use the show ethernet cfm maintenance-point local commands to verify the CFM over EVC
configuration. This command shows the basic configuration information for CFM.
