This is an event trap and does not involve the matching trap.

Parameters

Parameter Description
VrrpIfIndex Indicates the index of the interface where VRRP resides.
VrId Indicates the ID of VRRP.
IfIndex Indicates the index of the interface where VRRP resides.
IpAddress Indicates the Router id of the interface where VRRP resides.
NodeName Indicates the device name.
IfName Indicates the name of the VRRP interface.
CurrentState VRRP status after the change:

Impact on the System

  • If master/backup switchover occurs normally, services are not affected.

  • If master/backup switchover occurs abnormally, services may be interrupted.

Possible Causes

The status of VRRP configured on the device changed from MASTER to other status.

Procedure

  1. View the value of CurentState in the trap, check the status after the VRRP backup group changes, and perform operations according to the specific cause.

    • If the value of CurentState is Notactive, go to Step 2.
    • If the value of CurentState is Backup, go to Step 3.
    • If the value of CurentState is Initialize, go to Step 4.

  2. If the VRRP backup group in the Master state is deleted, you cannot view the configurations of the VRRP backup group by using the display vrrp command. You can check the operation records of command lines by viewing log information.
  3. Run the display vrrp command to check whether the set priorities of the VRRP backup group on the original master device and backup device are the same as the running priorities.

    • If so, go to Step 7.
    • If not, it indicates that the link monitored by the VRRP backup group is faulty and the priorities are increased or reduced. Locate the cause of the fault and restore the monitored link. Then, go to Step 4.

  4. If the original master device is faulty, locate the cause of the fault and restore the master device.

    • Check whether the interface where the VRRP backup group resides is normal, and then go to Step 6.
    • Check whether the link that the VRRP backup group monitors is normal, and then go to Step 7.
    • If the VRRP backup group and BFD are associated, check the link that BFD monitors and go to Step 5.

  5. Run the display vrrp command to check the status of the BFD session.

    • If the BFD session is Up, go to Step 8.
    • If the BFD session is Down, it indicates that the original active link is faulty. Locate the cause of the fault and restore the active link. Then, go to Step 9.

  6. Run the display vrrp command to check whether VRRP Advertisement packets can be normally received and sent.

    • If so, go to Step 8.
    • If not, it indicates that the link is faulty. Locate the cause of the fault and restore the link. Then, go to Step 9.

  7. Run the display vrrp command to view the interface that is monitored by the BFD session associated with the VRRP backup groups and then enter the interface view to run the display this interface command to detect the interface status.

    • If the interface status is Up, go to Step 8.
    • If the interface status is Down, it indicates that the link is faulty. Locate the cause of the fault and restore the active link. Then, go to Step 9.

  8. Collect information about configurations, trap messages, and log messages, and then contact technical support personnel.
  9. End.
