Chapter 41: CFM Commands
– 1275 –
suppress alarms since the received AIS information does not contain
that information. Therefore, upon reception of a frame with AIS
information, the MEP will suppress alarms for all peer MEPs whether
there is still connectivity or not.
•
However, for a point-to-point connection, a MEP has only a single peer
MEP for which to suppress alarms when it receives frames with AIS
information.
•
If suppression is enabled by this command, upon receiving a frame with
AIS information, a MEP detects an AIS condition and suppresses loss of
continuity alarms associated with all its peer MEPs. A MEP resumes loss
of continuity alarm generation upon detecting loss of continuity defect
conditions in the absence of AIS messages.

type – Specifies the CFM protocol’s creation method for
maintenance intermediate points (MIPs) in this domain:
default – MIPs can be created for any maintenance association
(MA) configured in this domain on any bridge port through
which the MA’s VID can pass.
explicit – MIPs can be created for any MA configured in this
domain only on bridge ports through which the MA’s VID can
pass, and only if a maintenance end point (MEP) is created at
some lower MA Level.
none – No MIP can be created for any MA configured in this
domain.
