Remote Maintenance
End Points
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.
Command Usage
â—† All MEPs that exist on other devices inside a maintenance association should be
statically configured to ensure full connectivity through the cross-check
process.
â—† 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.
â—† 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").
â—† SNMP traps for continuity check events discovered by cross-check operations
can also be configured on the Configure Global page (see "Configuring Global
Settings for CFM").
