Ethernet Cfm Domain - Edge-Core ES3528MV2 Management Manual

C
OMMAND
◆ For multipoint connectivity, a MEP cannot determine the specific
maintenance level entity that has encountered defect conditions upon
receiving a frame with AIS information. More importantly, it cannot
determine the associated subset of its peer MEPs for which it should
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
