Common Actionable Failures
It is important to note that AIS operates independently from the low-priority-defect setting. The
low-priority-defect setting configuration parameter affects only the ETH-CFM fault propagation
and alarming outside the scope of AIS. Any fault in the MEP state machine generates AIS when it
is configured. Table 4 illustrates the ETH-CC defect condition groups, configured low-priority-
defect setting, priority and defect as it applies to fault propagation.

DefMACStatus
(default)
macRemErrXcon MAC Layer Remote MEP is indicating a
remote port or interface not
operational.
2
DefRemoteCCM remErrXon No communication from
remote peer.
MEP is not receiving CCM
from a configured peer. The
timeout of CCM occurs at 3.5x
the local CC interval. As per
the specification, this value is
not configurable.
3
DefErrorCCM errXcon Remote and local configures
do not match required param-
eters.
Caused by different interval
timer, domain level issues
(lower value arriving at a MEP
configured with a higher
value), MEP receiving CCM
with its MEPID

DefXconn Xcon Cross Connected Service The service is receiving CCM
packets from a different associ-
ation. This could indicate that
two services have merged or
there is a configuration error on
one of the SAP or bindings of
the service, incorrect associa-
tion identification.
