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.
Example
This example suppresses sending frames with AIS information.
Console(config)#ethernet cfm ais suppress alarm md voip ma rd
Console(config)#
ethernet cfm domain
This command defines a CFM maintenance domain, sets the authorized
maintenance level, and enters CFM configuration mode. Use the
no form to delete
a CFM maintenance domain.
Syntax
ethernet cfm domain index index name domain-name level level-id
[ mip-creation type ]
no ethernet cfm domain index index
index – Domain index. (Range: 1-65535)
domain-name – Domain name. (Range: 1-43 alphanumeric characters)
level-id – Authorized maintenance level for this domain. (Range: 0-7)
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.
