OSPFV3_1.3.6.1.4.1.2011.5.25.147.0.1 hwOspfv3VirtIfStateChange

Description

OSPFV3/2/VIFCHANGE:OID [oid] The status of the virtual interface has changed. (AreaId=[integer], NbrRouterId=[gauge], RouterId=[gauge], VIfState=[integer], ChgReason=[integer])

The status of the OSPFv3 virtual link interface changed. A possible cause is that the router ID of the neighbor on the virtual link changed after the virtual link was configured or the status of the physical interface of the virtual link changed.

Attribute

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

AreaId

Indicates the ID of the OSPFv3 area. The value is a decimal integer.

NbrRouterId

Indicates the Router ID of the virtual neighbor. The value is a decimal integer.

RouterId

Indicates the Router ID of the local router. The value is a decimal integer.

VIfState

Indicates the state of the virtual link interface.
  • 1: Down
  • 2: Attempt
  • 3: Init
  • 4: 2-Way
  • 5: Exstart
  • 6: Exchange
  • 7: Loading
  • 8: Full

ChgReason

Indicates the reason for change in the state of an OSPFv3 virtual interface.
  • 1: No Event
  • 2: Interface Up
  • 3: Wait Timer Expired
  • 4: Backup Seen Occurred
  • 5: Neighbor Change Event Occurred
  • 6: Loop Ind
  • 7: Unloop Ind
  • 8: Interface Down

Impact on the System

This trap message is generated when the status of a virtual interface changes. This trap may affect the neighbor status. If the interface goes Down, the neighbor relationship will be interrupted.

Possible Causes

1. The status of the physical interface of the virtual link changed.

2. The router ID of the neighbor on the virtual link changed.

Procedure

  1. Run the display ospfv3 vlink command to check whether the status of the virtual link interface is Up.

    • If so, it indicates that this trap message is informational only, and no action is required. Then, go to Step 5.

    • If not, go to Step 2.

  2. Run the display ipv6 interface and display ospfv3 interface commands to check whether the interface status is Up.

    • If so, go to Step 3.

    • If not, check the connection between physical interfaces. After the interface turns Up, check whether the alarm is cleared.
      • If so, go to Step 5.

      • If not, go to Step 3.

  3. Run the display current-configuration configuration ospfv3 command to check whether the ID of the neighbor on the virtual link changes.

    • If so, modify the configurations of the two ends to be the same. Then check whether the trap is cleared.
      • If so, go to Step 5.

      • If not, go to Step 4.

    • If not, go to Step 4.

  4. Collect alarm information and configuration information, and then contact technical support personnel.
  5. End.
