Use the Administration > CFM (Configure Remote MEP – Add) page to
specify remote maintenance end points (MEPs) set on other CFM-enabled
devices within a common MA. Remote MEPs can be added to a static list in
this manner to verify that each entry has been properly configured and is
operational. When cross-checking is enabled, the list of statically
configured remote MEPs is compared against the MEPs learned through
continuity check messages (CCMs), and any discrepancies reported via
SNMP traps.

All MEPs that exist on other devices inside a maintenance association
should be statically configured to ensure full connectivity through the
cross-check process.
Remote MEPs can only be configured if local domain service access
points (DSAPs) have already been created (see "Configuring
Maintenance End Points" ) 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.
The MEP cross-check start delay which sets the maximum delay that a
device waits for remote MEPs to come up before starting the cross-
check operation can be configured on the Configure Global page (see
"Configuring Global Settings for CFM" ).
