clear-seconds }
The period after which a generated alarm is reported is set.
After such a period is set for an alarm, there are the following situations:
l If no recovery alarm is generated during the period, the alarm is not reported to the NMS
until the period expires.
l If a recovery alarm is generated during this period, the alarm and its recovery alarm are both
deleted from the alarm queue and will not be reported to the NMS.
You can use the parameter cause-period cause-seconds to set the period after which a generated
alarm is reported.
You can use the parameter clear-period clear-seconds to set the period after which a generated
recovery alarm is reported.
