Alarms/Errors
Unexp MEP (Unexpected MEP)
RX: A CCM frame was received from the peer MEP with same MEG/MD
Level, correct MEG ID/MAID, and correct source MAC Address
(corresponds to the peer MEP) but with unexpected MEP ID. The alarm
is cleared when no CCM frames with same MEG/MD Level, correct
MEG ID/MAID, correct source MAC Address (corresponds to the peer
MEP) but with an unexpected MEP ID are received within an interval
equal to 3.5 times the configured CCM transmission period.
Unexp Period (Unexpected Period)
RX: A CCM frame is received from the peer MEP with same MEG/MD
Level, correct MEG ID/MAID, and correct MEP ID but with a period field
value different than the one configured. The alarm is cleared when no
CCM frames with same MEG/MD Level, correct MEG ID/MAID, and
correct MEP ID but with incorrect period field value are received within
an interval equal to 3.5 times the configured CCM transmission period.
