OSPF_1.3.6.1.2.1.14.16.2.16 ospfIfStateChange

Trap Buffer Description

The status of the non-virtual interface changes. (RouterId=[RouterId], IfIpAddress=[IfIpAddress], AddressLessIf=[AddressLessIf], IfState=[IfState], ProcessId=[ProcessId], AreaId=[AreaId], IfnetIndex=[IfnetIndex], LocalIfIpAddress=[LocalIfIpAddress], IfName=[IfName], InstanceName=[InstanceName], IfChgReason=[IfChgReason])

The status of the non-virtual OSPF interface changed. The possible cause is that the interface working as a physical interface went Down.

Impact on the System

This trap may affect the neighbor status. If the interface goes Down, the neighbor relationship will be interrupted.

Possible Causes

Cause 1: The status of the physical interface alternated between Up and Down. Cause 2: The OSPF neighbor relationship was being established.

Procedure

1. Run the display ospf interface command to check whether the interface is Down.

If the interface is Down, go to Step 2.
If the interface is in another state, go to step 4.

2. Run the display interface [interface-type [interface-number]] command to check whether the interface is Up.

If the interface is Up, go to Step 3.
If the current interface is in another state, view the log file to check whether the shutdown command is configured on the interface.
If it is a misoperation, run the undo shutdown command on the interface. Otherwise, go to Step 4.
If the link is faulty, replace the link or go to step 3.

3. Contact technical support.

4. End.
