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.
