OSPF Enhanced Traffic Statistics

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.

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

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 10 traffic gigabitethernet 0/0/0

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

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

Displays OSPFv3 traffic statistics.

Step 3

clear ipv6 ospf traffic

Example:


Router# clear ipv6 ospf traffic

Clears OSPFv3 traffic statistics.
