◆
Use this command to statically configure remote MEPs that exist inside
the maintenance association. These remote MEPs are used in the cross-
check operation to verify that all endpoints in the specified MA are
operational.
◆
Remote MEPs can only be configured with this command if domain
service access points (DSAPs) have already been created with the
ethernet cfm mep command at the same maintenance level and in the
same MA. DSAPs are MEPs that exist on the edge of the domain, and
act as primary service access points for end-to-end cross-check, loop-
back, and link-trace functions.
