OSPF_1.3.6.1.2.1.14.16.2.13 ospfMaxAgeLsa

OSPF_1.3.6.1.2.1.14.16.2.13 ospfMaxAgeLsa

Description

OSPF/4/AGELSA:OID [oid]: An LSA is aged. (LsdbAreaId=[area-id], LsdbType=[lsa-type], LsdbLsid=[lsdb-ls-id], LsdbRouterId=[lsdb-router-id], ProcessId=[process-id], RouterId=[router-id], InstanceName=[instance-name])

LSAs in the LSDB of the router reached the maximum aging time. The possible cause was that the routes imported by OSPF were deleted or the OSPF interface was Down.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.2.1.14.16.2.13 Warning environmentalAlarm (6)

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

LsdbAreaId

Indicates the area ID of an aged LSA.

LsdbType

Indicates the type of an LSA.
  • 1: Router LSA
  • 2: Network LSA
  • 3: Summary LSA type 3
  • 4: Summary LSA type 4
  • 5: AS External LSA
  • 7: NSSA LSA
  • 9: Opaque LSA - scope Local
  • 10: Opaque LSA - scope area
  • 11: Opaque LSA - scope AS

LsdbLsid

Indicates the link state ID of an LSDB.

LsdbRouterId

Indicates the router ID of an LSDB.

ProcessId

Indicates the process ID.

RouterId

Indicates the router ID of the local router.

InstanceName

Indicates the instance name.

If the instance name is null, the OSPF process is a public process.

Impact on the System

In the case of Type 1 and Type 2 LSAs, services may be affected, and thus you need to check the interface or neighbor status. In the case of Type 3, Type 5, and Type 7 LSAs, only the routes associated with lsdb-ls-id will be affected.

Possible Causes

1. The interface was Up or Down.

2. The status of the neighbor changed.

3. The routes imported by OSPF changed.

Procedure

  1. Check the LsdbRouterId of the LSA in the trap.

    • If the LSA is generated by the local router, go to Step 2.

    • If the LSA is not generated by the local router, go to Step 4.

  2. Check the LSA type:

    • In the case of Type 1 and Type 2 LSAs, check whether the following alarms exist:

      1.3.6.1.2.1.14.16.2.1

      1.3.6.1.2.1.14.16.2.2

      1.3.6.1.2.1.14.16.2.3

      1.3.6.1.2.1.14.16.2.16
      • If so, handle the alarms according to the handling procedures of these alarms.

      • If not, go to Step 3.

    • In the case of Type 3, Type 5, and Type 7 LSAs, run the display ip routing-table lsdb-ls-id command to check whether the route exists or router flapping occurs.
      • Collect routing or flapping information, and go to Step 3.

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