CFM Commands
ethernet cfm ais suppress alarm
This command suppresses sending frames containing AIS information following the detection of
defect conditions. Use the no form to restore the default setting.
Syntax
[no] ethernet cfm ais suppress alarm md domain-name ma ma-name
domain-name – Domain name. (Range: 1-43 alphanumeric characters)
ma-name – Maintenance association name. (Range: 1-43 alphanumeric characters,
maximum length is 44 minus the length of the domain name)
Default Setting
Suppression is disabled
Command Mode
Global Configuration
Command Usage
• 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.
Example
This example suppresses sending frames with AIS information.
