Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

sysProcIndexofDyname

Index of the dynamic hostname of the local router

hwisisSysInstance

Conflicting system ID

hwisisSysLevelIndex

Level of the process in which system IDs conflicted

OwnSystemId

System ID of the local router

OwnDynamicName

Dynamic hostname of the local router

AdjSystemId

System ID of the neighbor

AdjDynamicName

Dynamic hostname of the neighbor

LocalIP

Local IP address

AdjIP

IP address of a neighbor

RemoteIP

IP address of the remote device with the conflicting system ID

Impact on the System

Link state protocol data units (LSPs) are frequently updated, and route flapping occurs.

Possible Causes

Two or more routers in the IS-IS area had the same system ID.

Procedure

  1. View the OwnSystemId and hwisisSysInstance parameters in the alarm information to check whether the system ID of the local router is the same as the conflicting system ID.

    • If the system ID of the local router is the same as the conflicting system ID, change the system ID of the local router. Then check whether the alarm is cleared. If the alarm is cleared, go to step 4. If the alarm persists, go to step 3.

    • If the system ID of the local router is different from the conflicting system ID, go to step 2.

  2. Check the system IDs of other routers on the network, and change the system IDs that are the same as the conflicting system ID in the alarm information, or run the undo isis system-id auto-recover disable command to enable the device to automatically resolve IS-IS system ID conflicts.. Then check whether the alarm is cleared.

    • If the alarm is cleared, go to step 4.

    • If the alarm persists, go to step 3.

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