After you enable alarm status re-check for a device, the device re-checks the status of a specified type of status change alarm and reports alarms again.
Alarms generated due to interface or protocol status changes are cleared after the system is reset. The alarms are not reported again. A status change alarm is triggered only when the status changes. As a result, this type of alarms cannot be found after the system is reset. Therefore, to enable the device to report alarms again after a system reset, enable alarm status re-check.
The system view is displayed.
The alarm management view is displayed.
The alarm status re-check function is enabled.
The configuration is committed.
