Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
This command enables Crosscheck on the maintenance end point (MEP) specified by the MEP ID number
(mep-id-number). The range for MEP ID numbers is 1 to 8191. Crosscheck is enabled when the first crosscheck
MEP is entered.
Repeat this command for every MEP that you want to include in the expected set of MEPs for crosscheck.
Crosscheck detects the following two additional defects for continuity-check messages (CCMs) on peer MEPs:
• Peer MEP missing—A crosscheck MEP is configured, but has no corresponding peer MEP from which
to receive CCMs.
• Peer MEP unexpected—A peer MEP is sending CCMs, but no crosscheck MEP is configured for it.
If more than one local MEP is configured for a service, all the local MEPs must be included in the list of
configured crosscheck MEPs.
