(Optional) Adjusting the Interval for PIM to Send Trap Messages

(Optional) Adjusting the Interval for PIM to Send Trap Messages


After Protocol Independent Multicast (PIM) is enabled on the switches, you can configure PIM management information base (MIB) notifications to set the interval for sending PIM events. Therefore, you can know the current status of various PIM events on the switches in real time. The PIM events include neighbor loss, neighbor addition, receiving invalid Join/Prune messages, RP-mapping change, interface being elected as the designated router (DR) and the event of receiving invalid Register messages.

Perform the following steps on the switch managed by the network management system.


  1. Run system-view

    The system view is displayed.

  2. Run multicast mib

    The multicast MIB view is displayed.

  3. Run pim mib-notification interval { interface-election-dr election-value | invalid-join-prune jp-value | invalid-register register-value | neighbor-loss loss-value | new-neighbor new-value | rp-mapping-change change-value }

    The interval for PIM to send trap messages is set.

    By default, the interval for sending trap messages for neighbor lost and neighbor addition is 0 seconds. That is, once the event occurs, PIM reports it immediately.

    The default interval for sending the trap of event of receiving invalid Join/Prune messages, the RP-mapping change event, the event of the interface being elected as the DR or the event of receiving invalid Register messages is 65535 seconds. After the events of these types occur, PIM does not report them.


    To configure PIM to report these events, you can run the pim mib-notification interval command to set an interval smaller than 65535 seconds.

  4. Run commit

    The configuration is committed.
