Basic Configuration Steps for CFM

1.

Configure the maintenance domains with the

ethernet cfm domain

command.

2.

Configure the maintenance associations with the

ma index name

command.

3.

Configure the local maintenance end points (MEPs) which will serve as
the domain service access points for the specified maintenance

association using the

ethernet cfm mep

command.

4.

Enter a static list of MEPs assigned to other devices within the same
maintenance association using the

mep crosscheck mpid

command.

This allows CFM to automatically verify the functionality of these

remote end points by cross-checking the static list configured on this

device against information learned through continuity check messages.
