Disabling MPLS L2VPN Alarm Verification

Disabling MPLS L2VPN Alarm Verification


If MPLS L2VPN alarm verification is enabled on a device, the device regularly sends service alarms to the fault management (FM) module until these alarms are cleared. The FM then compares received alarms with locally stored alarms. If a received alarm is different from any of the locally stored alarms, the FM module reports the alarm to the NMS. If a received alarm is the same as a locally stored alarm, the FM module does not report this alarm.

If a large number of services exist, MPLS L2VPN alarm verification may regularly drive the CPU usage to a high level, affecting service performance. In this case, you can disable MPLS L2VPN alarm verification.


  1. Run the system-view command to enter the system view.
  2. Run the mpls l2vpn command to enter the MPLS L2VPN view.
  3. Run the mpls l2vpn alarm verification disable command to disable MPLS L2VPN alarm verification.

    By default, MPLS L2VPN alarm verification is enabled.

    After MPLS L2VPN alarm verification is disabled, the device does not periodically send service alarms to the FM module, and the FM module cannot age out cleared alarms.
