Description
This command is used to enable or disable the CFM function on a per-port basis. By default, the
CFM function is disabled on all ports. If the CFM is disabled on a port:
• MIPs are never created on that port.
• MEPs can still be created on that port, and the configuration can be saved.
• MEPs created on that port can never generate or process CFM PDUs. If the user issues a
Loopback or Link trace test on those MEPs, it will prompt the user to inform them that the
CFM function is disabled on that port
Format
config cfm ports <portlist> state [enable | disable]
Parameters
<portlist> - Specify the logical port list.
state - Specify the CFM function status.
