OSPF Enhanced Traffic Statistics for OSPFv2 and OSPFv3

This document describes new and modified commands that provide enhanced OSPF traffic statistics for OSPFv2 and OSPFv3. The ability to collect and display more detailed traffic statistics increases high availability for the OSPF network by making the troubleshooting process more efficient.

New OSPF traffic statistics are collected and displayed to include the following information:

  • OSPF Hello input queue and OSPF process queue status and statistics.
  • Global OSPF traffic statistics.
  • Per OSPF interface traffic statistics.
  • Per OSPF process traffic statistics.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Prerequisites for OSPF Enhanced Traffic Statistics

OSPFv2 or OSPFv3 must be configured on the router.

Information About OSPF Enhanced Traffic Statistics

The OSPF enhanced traffic statistics are enabled by default and cannot be disabled. The detailed OSPF traffic statistics are especially beneficial for troubleshooting the following types of OSPF instabilities:

  • OSPF process queue status and statistical information can help the network administrator determine if an OSPF process can handle the amount of traffic sent to OSPF.
  • OSPF packet header errors and LSA errors statistics keep a record of different errors found in received OSPF packets.

OSPF enhanced traffic control statistics also monitor the amount of traffic control exchanged between OSPF processes--an important consideration in network environments with slow links and frequent topology changes.

How to Display and Clear OSPF Enhanced Traffic Statistics

Displaying and Clearing OSPF Traffic Statistics for OSPFv2

Before You Begin

Your network must run IPv4 to collect, display and clear detailed traffic statistics for Hello output, process queue status, global OSPF traffic statistics, per OSPF interface traffic statistics and per OSPF process traffic statistics.

SUMMARY STEPS

    1.    enable

    2.    show ip ospf [process-id] traffic[interface-type interface-number]

    3.    clear ip ospf traffic


DETAILED STEPS
      Command or Action Purpose
    Step 1 enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 show ip ospf [process-id] traffic[interface-type interface-number]


    Example:
    Router# show ip ospf traffic statistics
     

    Displays OSPFv2 traffic statistics.

     
    Step 3 clear ip ospf traffic


    Example:
    Router# clear ip ospf traffic
     

    Clears OSPFv2 traffic statistics.

     

    Displaying and Clearing OSPF Traffic Statistics for OSPFv3

    Before You Begin

    Your network must run IPv6 to collect, display and clear detailed traffic statistics for Hello output, process queue status, global OSPF traffic statistics, per OSPF interface traffic statistics and per OSPF process traffic statistics.

    SUMMARY STEPS

      1.    enable

      2.    show ipv6 ospf [process-id] traffic[interface-type interface-number]

      3.    clear ipv6 ospf traffic


    DETAILED STEPS
        Command or Action Purpose
      Step 1 enable


      Example:
      Router> enable
       

      Enables privileged EXEC mode.

      • Enter your password if prompted.
       
      Step 2 show ipv6 ospf [process-id] traffic[interface-type interface-number]


      Example:
      Router# show ipv6 ospf traffic statistics
       

      Displays OSPFv3 traffic statistics.

       
      Step 3 clear ipv6 ospf traffic


      Example:
      Router# clear ipv6 ospf traffic
       

      Clears OSPFv3 traffic statistics.

       

      Configuration Examples for OSPF Enhanced Traffic Commands

      Displaying and Clearing Enhanced Traffic Statistics for OSPFv2 Example

      The following example shows display output for the show ip ospf traffic command for OSPFv2:

      The network administrator can issue the clear ip ospf traffic command to reset all counters and restart all statistics collections:

      Router# clear ip ospf traffic
