Configuring a Suppression Period for an Alarm

You can configure a suppression period for an alarm to prevent the alarm from being reported frequently.

Context

Alarm reporting frequently affects fault locating efficiency. To prevent the system from reporting a large number of invalid alarms, you can enable delayed alarm reporting and configure a suppression period for an alarm, so that the alarm is not reported to the NMS within the period.

After a suppression period is configured for an alarm, the following situations occur:

If the alarm is generated but its clear alarm is not generated, the alarm is reported to the NMS only after the suppression period elapses.
If both the alarm and its clear alarm are generated during this period, they are both deleted from the alarm queue and will not be reported to the NMS.

Procedure

Run system-view
The system view is displayed.
Run alarm
The alarm management view is displayed.
Run suppression alarm-name alarm-name { cause-period cause-seconds | clear-period clear-seconds }
The alarm suppression period is set.

cause-period cause-seconds specifies the period after which a generated alarm is reported.

clear-period clear-seconds specifies the period after which a generated clear alarm is reported.
Run commit
The configuration is committed.
