Understanding Fault Management
Alarms are reported if a fault is detected. Classifying,
associating, and processing received alarms help keep you informed
of the running status of devices and helps you locate and analyze
faults rapidly.
Table 1 lists the alarm functions supported
by the HUAWEI.

Description
|
Alarm masking
|
Maintenance engineers can configure alarm masking on terminals
so that terminals detect only alarms that are not masked. This function
helps users ignore the alarms that do not need to be displayed.
|
Alarm suppression
|
Alarm suppression can be classified as jitter suppression
or correlation suppression.
Jitter suppression: uses alarm continuity analysis to allow
the device not to report the alarm if a fault lasts only a short period
of time and to display a stable alarm generated if a fault flaps.
Correlation suppression: uses alarm correlation rules to reduce
the number of reported alarms, reducing the network load and facilitating
fault locating.
