2.1 Configuring Alarms

Alarm management includes the following functions: alarm record, alarm setting, and alarm
statistics. These functions help you to maintain the device and ensure that the device works
efficiently.
Context
An alarm refers to the notification of the system after a fault is detected. After an alarm is
generated, the system broadcasts the alarm to the terminals, mainly including the NMS and
command line interface (CLI) terminals.
Alarms are classified into fault alarm and recovery alarm. After a fault alarm is generated at a
certain time, the fault alarm lasts till the fault is rectified to clear the alarm.
You can modify the alarm settings according to your requirements. The settings are alarm
severity, alarm output mode through the CLI and alarm statistics switch.
When managing alarms on the GUI through the NMS, you can set filtering criteria to mask
unimportant alarms and events. Such filtering function facilitates the focus of the important
alarms and eliminates the load of the NMS.

Clear alarms.
You can run the alarm active clear command to clear the alarms that are not recovered in
the system.
– When an active alarm lasts a long time, you can run this command to clear the alarm.
– Before clearing an alarm, you can run the display alarm active command to query the
currently active alarms.
Configure alarm level.
Run the alarm alarmlevel command to configure the alarm level.
– Alarm levels are critical, major, minor, and warning.
– Parameter default indicates restoring the alarm level to the default setting.
– You can run the display alarm list command to query the alarm level.
– The system specifies the default (also recommended) alarm level for each alarm. Use
the default alarm level unless otherwise required.
Configure alarm jitter-proof.
Run the alarm jitter-proof command to configure the alarm jitter-proof function and the
jitter-proof period.
– To prevent a fault alarm and its recovery alarm from being displayed frequently, you
can enable the alarm jitter-proof function to filter alarms in the system.
– After the alarm jitter-proof function is enabled, the alarm in the system is not reported
to the NMS immediately but is reported to the NMS after an alarm jitter-proof period.
– If an alarm is recovered in an alarm jitter-proof period, the alarm is not reported to the
NMS.
