OSPF_1.3.6.1.2.1.14.16.2.15 ospfLsdbApproachingOverflow

OSPF_1.3.6.1.2.1.14.16.2.15 ospfLsdbApproachingOverflow

Description

OSPF/3/APPROFLOW:OID [oid]: The LSDB is approaching overflow. (ProcessId=[process-id], RouterId=[router-id], ExtLsdbLimit=[lsa-limit], InstanceName=[instance-name])

The Overflow feature restricts only the total number of Type 5 and Type 7 LSAs. The total number of type 5 and type 7 LSAs in the LSDB of the router exceeded 90% of the maximum value defined by ospfExtLsdbLimit. The possible cause was that the number of routes imported by OSPF reached or exceeded the configured threshold. This trap was generated when the number of OSPF external routes in the network reached or exceeded 90% of the configured overflow limit.

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

ProcessId

Indicates the process ID.

RouterId

Indicates the ID of the switch that generates the trap message.

ExtLsdbLimit

Indicates the maximum total number of type 5 and type 7 LSAs.

InstanceName

Indicates the instance name.

Impact on the System

The total number of type 5 and type 7 LSAs exceeds the limit allowed by overflow. The excessive type 5 and type 7 LSAs are discarded.

Possible Causes

Too many type 5 and type 7 LSAs existed in the LSDB.

Procedure

  1. Run the display ospf lsdb brief command to check whether the total number of type 5 and type 7 LSAs exceeds 90% of the overflow limit.

    • If so, go to Step 2.

    • If not, go to Step 3.

  2. Perform the following operations as required:

    • If it is allowed to adjust the maximum number of external LSAs in the OSPF LSDB, run the lsdb-overflow-limit command to reconfigure the maximum value. Wait for a certain period and check whether the alarm cleared. If so, go to Step 4. If not, go to Step 3.

    • If it is not allowed to adjust the maximum number of external LSAs in the OSPF LSDB, go to Step 3.

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