Command Usage
◆ An interface must be enabled before a MEP can be created with the ethernet
cfm mep command.
◆ If a MEP has been configured on an interface with the ethernet cfm mep
command, it must first be deleted before CFM can be disabled on that
interface.
◆ When CFM is disabled, hardware resources previously used for CFM processing
on that interface are released, and all CFM frames entering that interface are
forwarded as normal data traffic.
