LOC
LOC (Loss of Continuity)
The OT port has detected a loss of continuity at the MEP layer. A MEP detects LOC with
a peer MEP when it stops receiving CCM frames from that peer ME. Such a defect
condition can be caused by hard failures such as a link failure/device failure, or soft
failures such as memory corruption, or misconfigurations.
Severity
Service affecting?
Applicability
This alarm is raised when an MEP receives CCM frames with an incorrect MEG ID. The
alarm is cleared when the MEP does not receive CCM frames with the correct MEG ID.
