Setting the Alarm Severity

Context

The system defines default alarm severity for each alarm. Users can change the alarm severity. When receiving alarms reported by a device, the NMS can configure filtering rules to display only alarms of a specified severity.

As defined in X.733, alarms are classified into six severities, as described in Table 1. A smaller value indicates a higher severity.

**Table 1** Descriptions of alarm severities
Value	Severity	Description
1	Critical	Indicates that a fault affecting services has occurred and it must be rectified immediately.
2	Major	Indicates that services are being affected and related measures need to be taken urgently.
3	Minor	Indicates that a fault occurs but does not affect services. To avoid a minor alarm from getting severer, related measures must be immediately taken.
4	Warning	Indicates that a potential or impending service-affecting fault is detected before any significant effects have been felt. Take corrective actions to diagnose and rectify the fault.
5	Indeterminate	Indicates that the severity of an alarm cannot be determined.
6	Cleared	Indicates that one or more previous alarms have been cleared.
