Usage Guidelines
Alarms are suppressed when a MEP goes into an RX AIS (receipt of an AIS frame) defect condition.
When you specify the level keyword with the ais command, you can transmit AIS messages to a higher
maintenance association without configuring a maintenance intermediate point (MIP) for that
maintenance association.
Output of the show running all command shows "ais expiry-threshold 3.5" when the default expiry
threshold is configured, "ais period 60" when the default transmission period is configured, and "no ais
suppress-alarms" when the default value for the suppress-alarms option is configured.

ais [expiry-threshold threshold | level level-id | period seconds | suppress-alarms]
no ais [expiry-threshold | level | period | suppress-alarms]
(Optional) Configures the expiry threshold.
(Optional) Integer from 2 to 255 that is a count. If no MEPs are received
within an interval of the threshold multiplied by the transmission period, the
MEP clears the AIS defect condition. The default is 3.5.
(Optional) Indicates a maintenance level where AIS frames for maintenance
endpoints (MEPs) belonging to the service will be sent.
(Optional) Integer from 0 to 7 that identifies the maintenance level.
(Optional) Configures the AIS transmission period for all MEPs in the
maintenance association.
(Optional) Integer value 1 or 60 that indicates the AIS transmission period
in seconds. The default is 60.
