Configuring Alarm Correlation Suppression

Configuring Alarm Correlation Suppression


Before configuring alarm correlation suppression, enable alarm correlation analysis to analyze alarm types including root-cause and non-root-cause. For a non-root-cause alarm, the system marks the sequence number of its root-cause alarm on the non-root-cause alarm. After alarm correlation suppression is configured, the system filters out non-root-cause alarms and reports only root-cause alarms to the NMS.


  1. Run system-view

    The system view is displayed.

  2. Run alarm

    The alarm view is displayed.

  3. Run correlation-analyze enable

    Alarm correlation analysis is enabled.

    By default, alarm correlation analysis is disabled.

  4. Run the following commands to configure NMS-based alarm correlation suppression.

    • Run alarm correlation-suppress enable target-host ip-address securityname { securityname | cipher securityname } [ vpn-instance vpn-instance-name ]

      Alarm correlation suppression based on the NMS IPv4 address is enabled.

    • Run alarm correlation-suppress enable target-host ipv6 ipv6-address securityname { securityname | cipher securityname } [ vpn-instance vpn-instance-name ]

      Alarm correlation suppression based on the NMS IPv6 address is enabled.

    By default, NMS-based alarm correlation suppression is enabled.

  5. Run commit

    The configuration is committed.
