MMG
MMG (Mismerge)
The OT port has detected a mismerge at the MEP layer. A MEP detects mismerge when it
receives a CCM frame with a correct MEG level that is, the MEG level is the same as the
MEP's own MEG level) but incorrect MEG ID (indicating that frames from a different
service instance are merged with the service instance represented by the MEP's own MEG
ID). Such a condition is most likely caused by misconfiguration, but could also be caused
by a hardware/software failure in the network.
Severity Major
Service affecting? No
Applicability 11DPE12E
This alarm is raised when an MEP receives CCM frames with the correct MEG level, but
an incorrect MEG ID. The alarm is cleared when the MEP does not receive CCM frames
with the correct MEG ID.
