Impact on the System

If the interface status of the virtual link changes from Down to P2P (Point-to-Point), this trap message is informational only, and no action is required. If the interface status of the virtual link changes from P2P to Down, the virtual link will be disconnected, the OSPF route calculation will be incorrect, and services may be interrupted.

Possible Causes

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

2. Router ID of the neighbor on the virtual link changed.

Procedure

  1. Run the display ospf vlink command to check whether the interface status of the virtual link is P2P.

    • If so, it indicates that this trap message is informational only, and no action is required. Go to Step 4.
    • If not, go to Step 2.

  2. Run the display ospf process-id routing router-id neighbor-router-id command to check whether the area has the route to the remote switch.

    • If so, collect the configuration of the remote switch, and go to Step 3.
    • If not, run the display ospf interface command to check whether the status of the local interface is Down.
      • If so, run the display rm interface or display ip interface command to check whether the local interface goes Down.
        • If so, collect interface information, and go to Step 3.
        • If not, collect log information, and go to Step 3.
      • If not, collect the configuration of the remote switch, and go to Step 3.

  • 5 (configureChange): indicates that the OSPF configuration changes.
  • 6 (peerRouterReason): indicates that an alarm is generated because of the neighboring router.
  • 100 (alarmCleared): indicates that the alarm is cleared because services are restored or the neighbor is deleted.

Impact on the System

When the status of the neighbor (not a neighbor of a virtual link) changes, this trap message will be sent. This trap message indicates the status of the neighbor changes. If the neighbor changes from a lower status to a higher status, this trap message is informational only, and no action is required. If the neighbor changes from a higher status to a lower status, services may be interrupted. (The state transition of the OSPF neighbor in an ascending order is: Down -> Init -> 2-way -> Exstart -> Exchange -> Loading -> Full).

On a non-broadcast multi-connection or broadcast network, if the neighbor relationship enters a lower level of state, only the DR generates an ospfNbrStateChange alarm. If the neighbor relationship status change results from an interface down event on the DR, the DR does not generate this alarm but generates an ospfIfStateChange alarm. When the neighbor relationship status becomes stable, the ospfNbrStateChange alarm is cleared only on the DR. If the interface that went down is a non-DR interface, the ospfNbrStateChange alarm may persist.

Possible Causes

1. The status of the interface of the neighbor changed.

2. The configured parameters (such as Hello timer, dead timer, interface authentication, and network type) of the interfaces that set up the neighbor relationship were inconsistent.

3. OSPF was restarted by using the reset ospf process command.

4. An error packet was received.

5. The overflow function is configured and the process entered the Overflow state.

6. The ping operation failed, which indicated that an error occurred during the transmission of the packet.

Procedure

  1. Run the display ospf peer command to check the neighbor status. If the neighbor is in the Full state, go to Step 7; otherwise, go to Step 2.
  2. Run the display ip interface interface-type interface-number command to check whether the interface of the neighbor is in the Down state.

    • If the physical interface is Up, go to Step 3.

    • If the physical interface is Down, check whether the shutdown command is configured on the interface and the link.
      • If this command is configured, run the undo shutdown command and then go to Step 3.
      • If this command is not configured, go to Step 8.

  3. Check whether the packet is correctly forwarded and ping the IP address of the remote interface.

    • If the ping fails, go to Step 7.

    • If the ping succeeds, go to Step 4.

  4. Run the display ospf interface interface-type interface-number command to view the state field and check whether the interface where the OSPF neighbor resides is in the Down state.

    • If the interface is in the Down state, go to Step 7.

    • If the interface is in another state, go to Step 5.

  5. Run the display ospf interface interface-type interface-number command to check whether the configurations (including the hello interval, dead interval, poll interval, and OSPF network-type) on the two ends of the link are consistent and whether the interface on one end is not an OSPF interface.

    • If so, go to Step 6.

    • If not, modify the configurations to make them consistent. Then check whether the trap is cleared.

      • If so, go to Step 6.

      • If not, run the following commands to modify interface configurations on the two ends to be consistent.
        • ospf timer hello interval
        • ospf timer dead interval
        • ospf timer poll interval
        • ospf network-type { broadcast | nbma | p2mp | p2p }
        Then, check whether the trap is cleared.

        • If so, go to Step 8.

        • If not, go to Step 7.

  6. Run the display current-configuration interface interface-type interface-number command to check whether the interface authentication configurations on the two ends are consistent.

    • If so, go to Step 7.

    • If not, run the following commands to modify interface configurations on the two ends to be consistent.
      • ospf authentication-mode { simple [ plain plain-text | [ cipher ] cipher-text ] | null }
      • ospf authentication-mode { md5 | hmac-md5 | hmac-sha256 } [ key-id { plain plain-text | [ cipher ] cipher-text } ]
      • ospf authentication-mode keychain keychain-name
      Then, check whether the trap is cleared.

      • Y=>8.

      • N=>7.

      To ensure high security, it is recommended that the simple, md5, hmac-md5, and null authentication modes be not used.

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

InstanceName

Indicates the instance name.

Impact on the System

This trap message will be generated when the status of the neighbor on the virtual link changes. If the status of the neighbor on the virtual link changes from Full to lower than Full, routes are incorrectly installed to the routing table, or some routes are wrongly deleted. This may affect services.

Possible Causes

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

2. The configured parameters (such as Hello timer, dead timer and interface authentication) of the interfaces that set up the neighbor relationship were inconsistent.

3. OSPF was restarted by using the reset ospf process command or the active/standby switchover was performed.

4. An error packet was received.

5. The overflow function is configured and the process entered the Overflow state.

6. Routes of the area configured with the virtual link were added or deleted.

7. The ping operation failed, which indicated that an error occurred during the transmission of the packet.

Procedure

  1. Run the display ospf interface and display ip interface brief commands to check whether the status of the interface used to establish the virtual link is normal.

    • If the physical interface is Down, check whether the link or interface is configured with the shutdown command.

    • If the protocol status of the interface is Down, check whether the interface is configured with an IP address.

    If the interface status is normal, go to Step 2.

  2. Run the display ospf peer command to check whether the OSPF neighbor relationship is normal.

    • If the neighbor relationship is abnormal, check whether trap 1.3.6.1.2.1.14.16.2.2 exists. If the trap exists, locate the problem according to the trap. If the trap does not exist, go to Step 6.

    • If the neighbor relationship is normal, go to Step 3.

  3. Run the display ospf routing router-id [ router-id ] command to check whether the switch object exists. router-id indicates the IP address of the neighbor on the virtual link.

    • If the route does not exist, go to Step 4.

    • If the route exists, go to Step 5.

  4. Configure the route to the neighbor of the virtual link. Then check whether the trap is cleared.

    • If so, go to Step 7.

    • If not, go to Step 5.

  5. Run the display ospf vlink and display current- configuration configuration ospf commands to check whether the configurations (including the Hello interval, Dead interval, and poll interval) on the two ends of the virtual link are consistent.

    • If the configurations are correct, check whether trap 1.3.6.1.2.1.14.16.2.14 exists.

      • If the trap exists, rectify the fault according to the related procedure of the trap.

      • If the trap does not exist, go to Step 6.

    • If not, run the following command to modify the configurations on the two ends to be consistent.

      vlink-peer router-id [ dead dead-interval | hello hello-interval | retransmit retransmit-interval | smart-discover | trans-delay trans-delay-interval | [ simple [ plain plain-text | [ cipher ] cipher-text ] | { md5 | hmac-md5 | hmac-sha256 } [ key-id { plain plain-text | [ cipher ] cipher-text } ] | authentication-null | keychain keychain-name ] ] *

      Then, check whether the trap is cleared.

      • If so, go to Step 7.

      • If not, go to Step 6.

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

Indicates the MIB object ID of the alarm.

AreaId

Indicates the area ID of the NSSA.

ProcessId

Indicates the process ID.

RouterId

Indicates the ID of the switch that generates the trap.

NSSATranslatorState
Indicates the new status of the translator in the NSSA.
  • 1: ENABLED
  • 2: ELECTED
  • 3: DISABLED

InstanceName

Indicates the instance name.

Impact on the System

ASE routes may flap for a short period in the following situations. The role of the NSSA ABR changes; the Type 5 LSAs translated from Type 7 LSAs need to be flushed; or a new translator is translating Type 7 LSAs to Type 5 LSAs. Moreover, the translator role changes without manual configuration mostly because the topology in the backbone area or the NSSA changes.

Possible Causes

1. The parameter translator-always in the nssa command was manually configured or canceled on an ABR in the NSSA.

2. A new router ID was configured on an ABR in the NSSA and took effect.

3. A new switch joined the NSSA or a switch exited from the NSSA.

4. The OSPF protocol was restarted or the master/slave switchover was performed on a switch in the backbone area or the NSSA. This caused topology change in the NSSA.

5. The nssa command was manually configured or parameters in the nssa command were manually modified, which caused topology flapping in the backbone area or the NSSA. For example, configuring or canceling the parameter no-summary or no-import-route in the nssa command will lead to the reestablishment of the neighbor relationship between the local switch and a switch in the backbone area and between the local switch and a switch in the NSSA.

6. The role of the local switch changed to ABR or changed from ABR.

7. The topology of the backbone area or the NSSA changed. As a result, the local switch cannot reach another ABR with a greater router ID or with the parameter translator-always from the backbone area or the NSSA.

Procedure

  1. If the nssa translator-always command is configured or canceled manually on the local switch, run the display ospf brief command to check whether the translator role of the local switch in the NSSA is correct.

    • If the nssa translator-always command is configured, run the display ospf brief command to check whether the status of the NSSA translator is always. If so, go to Step 8. If not, go to Step 7.

    • If the configuration about nssa translator-always is canceled, run the display ospf brief command to check the status of the NSSA translator. If the status is disabled, go to Step 2. If the status is elected, go to Step 8.

  2. A possible cause is that the nssa translator-always command is configured on an ABR in the NSSA. You can run the display ospf lsdb router command to check whether the Router-LSA of some ABR in the NSSA contains the Nt bit. Alternatively, you can check whether the nssa translator-always is configured on the ABRs.

    • If the Router-LSA of some ABR contains the Nt bit or an ABR has been configured with the nssa translator-always command, go to Step 8.

    • If there is no ABR whose Router-LSA contains the Nt bit or no ABR is configured with the nssa translator-always command, go to Step 3.

  3. If a new router ID is configured on the local switch and already takes effect, check whether the translator role of the local switch in the NSSA is correct after the topology in the area becomes stable.

    • If so, go to Step 8.

    • If not, go to Step 4.

  4. A possible cause is that a new router ID is configured on an ABR in the NSSA. In this case, check the configurations of the other ABRs.

    • If the router ID of an ABR is changed, check whether the newly configured router ID is greater than the local router ID after the topology in the NSSA is stable.

      • If so, go to Step 8.

      • If not, go to Step 5.

    • If the router ID of an ABR remains unchanged, go to Step 5.

  5. If a new switch joins the NSSA, do as follows as required:

    • If the new joint switch is an ABR, check whether the router ID of the ABR is greater than the local router ID after the topology in the NSSA is stable.

      • If so, go to Step 8.

      • If not, go to Step 6.

    • If the new joint switch is not an ABR, go to Step 6.

  6. Check whether the local switch and the neighboring switch have traps , 1.3.6.1.2.1.14.16.2.2, , and 1.3.6.1.2.1.14.16.2.16.

    • If the preceding traps are generated, refer to the corresponding fault location processes.
    • If the preceding traps are not generated, go to Step 7.

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

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

ProcessId

Process ID

AreaId

Area ID

SelfIfnetIndex

Index of an interface

NbrIpAddr

IP address of a neighbor

RouterId

Local router ID

NbrRtrId

Router ID of a neighbor

Impact on the System

If the same router ID is configured for any two routers, it will cause the router lSA to be refreshed frequently. As a result, route flapping will occur.

Possible Causes

The same router ID was configured for at least two indirectly connected switch devices within one area, causing the router lSA to be refreshed frequently and route flapping.

Procedure

  1. Check whether the router ID in the alarm is the same as that of a neighbor.

    • If they are the same, go to Step 2.
    • If they are different, go to Step 4.

  2. Run the display current-configuration command to check whether the current configuration contains the undo ospf router-id auto-recover disable command.

    • If the current configuration contains the undo ospf router-id auto-recover disable command, go to Step 4.
    • If the current configuration does not contain the undo ospf router-id auto-recover disable command, go to Step 3.

  3. Run the undo ospf router-id auto-recover disable command to enable the automatic recovery function, and select a new router ID for a switch. Then, check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 6.
    • If the alarm persists, go to Step 5.

  4. Run the ospf router-id router-id command to configure a new router ID for a switch. Run the reset ospf command to restart the OSPF process. Then, check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 6.
    • If the alarm persists, go to Step 5.

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