ISIS_1.3.6.1.4.1.2011.5.25.24.2.4.1 hwIsisSystemIdConflict

Description

ISIS/2/SYSTEM_ID_CONFLICT:OID [oid] System ID may conflict.(sysProcIndexofDyname=[integer], hwisisSysInstance=[integer], hwisisSysLevelIndex =[integer], OwnSystemId=[opaque], OwnDynamicName=[string], AdjSystemId=[opaque], AdjDynamicName=[string], LocalIP=[hwIsisLocalIP], AdjIP=[hwIsisAdjIP], RemoteIP=[hwIsisRemoteIP])

Intermediate System to Intermediate System (IS-IS) detected that system IDs conflicted.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.24.2.4.1	Major	communicationsAlarm(2)

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

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