Cross Check Operations
– 801 –
Command Usage
â—† 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.
â—† 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.
Example
This example defines a static MEP for the specified maintenance association.
Console(config)#ethernet cfm domain index 1 name voip level 3
Console(config-ether-cfm)#ma index 1 name rd vlan 1
Console(config-ether-cfm)#mep crosscheck mpid 2 ma rd
Console(config-ether-cfm)#
ethernet cfm mep
crosscheck
This command enables cross-checking between the static list of MEPs assigned to
other devices within the same maintenance association and the MEPs learned
through continuity check messages (CCMs). Use the disable keyword to stop the
cross-check process.

cross-check operation to verify that all endpoints in the specified MA are
operational.
