Table of contents

Updated December 29, 2016

Overview

This is an example of how a configuration looks on a Cisco ISR 4300 Series Router.

Environment

  • All NTA versions
  • Cisco IOS XE 3S

Steps

 

  1. Configure the record with following commands:
    flow record NTA
    description config for NTA
    match ipv4 tos
    match ipv4 protocol
    match ipv4 source address
    match ipv4 destination address
    match transport source-port
    match transport destination-port
    collect transport tcp flags
    collect tinterface input
    collect tinterface output
    collect counter bytes long
    collect counter packets long
  2. Configure the exporter with following commands:
    flow exporter NTA
    description Exporter for NTA
    source Loopback0
    destination <Solarwinds IP>
    transport udp 2055
    template data timeout 60
  3. Configure the monitor with following commands:
    flow monitor NTA
    exporter NTA
    record NTA
    cache timeout active 60
  4. Attach to the interfaces you plan to monitor:
    ip flow monitor NTA input

    ip flow monitor NTA output

Note: Use only input or output or both of them according to your NetFlow monitoring topology.

If only one interface is configured to export Netflow user both commands on the interface.  

If there are multiple interfaces configured to export Netflow only use the " IP flow monitor 'name' input" commands on all interface.
