SNMP Server Traps
CCM frames with ETH-CC information allow detection of different defect conditions,
which include:
•
Remote Detect Indication Condition
The
rdi
trap is shown when a MEP detects RDI with it receives a CCM frame with
the RDI field set.
•
Loss of Continuity (LOC) Condition
The
loc
trap is shown if no CCM frames from a peer MEP are received within the
interval equal to 3.5 times the receiving CCM transmission period.
•
Mismerge Condition
The
mmg
trap is shown when a CCM frame with same MEG level but with a MEG ID
different than the receiving MEP
’s own MEG ID is received.
•
Unexpected MEP Condition
The
unm
trap is shown when a CCM frame with an incorrect MEP ID, including re-
ceiving MEP
’s own MEP ID, is received.
•
Unexpected MEG Level Condition
The
uml
trap is shown when a CCM frame with a MEG level lower than the receiving
MEP
’s MEG level is received.
•
Unexpected Period Condition
The
unp
trap is shown when a CCM frame is received with a period field value
different than the receiving MEP
’s own CCM transmission period.
To generate SNMP traps when detecting one of the defect conditions, use the following
