Configuring an Alarm Filtering Table to Filter Out Alarms

This section describes how to edit and apply an alarm filtering table. An alarm filtering table can be used by different terminal users to filter out the alarms that they are not concerned about.

Context

Terminal users include command line users and NMS users. Different users are concerned about different types of alarms. Terminal users can configure an alarm filtering table to filter out the unwanted alarms.

Flexible filtering rules can be defined in an alarm filtering table.

Filtering out alarms with the specific severity, such as alarms with the severity lower than Major
Filtering out alarms that are generated for a specific service, such as alarms for the MPLS service
Filtering out alarms with specific names, such as an LDP session alarm

Different terminal users can share the same alarm filtering table, but each terminal user can use only one alarm filtering table.
