Configuring Flow Monitoring on an MX Series Router with MS-MIC and MS-MPC for NetFlow Analyzer

    Follow these steps to configure Juniper flow monitoring with NetFlow Analyzer:

    The following example demonstrates how to configure Junos Traffic Vision for flow monitoring

    Enabling the Services Interface Card

    set interfaces ms-2/0/0 unit 0 family inet

    Configuring the Template and Timers

    set services flow-monitoring version9 template template1
    set services flow-monitoring version9 template template1 flow-active-timeout 120
    set services flow-monitoring version9 template template1 flow-inactive-timeout 60
    set services flow-monitoring version9 template template1 ipv4-template
    set services flow-monitoring version9 template template1 template-refresh-rate packets 100
    set services flow-monitoring version9 template template1 template-refresh-rate seconds 600
    set services flow-monitoring version9 template template1 option-refresh-rate packets 100
    set services flow-monitoring version9 template template1 option-refresh-rate seconds 600

    Configuring Service Set Properties

    set services service-set ss1 jflow-rules sampling
    set services service-set ss1 sampling-service service-interface ms-2/0/0.0

    Configuring Forwarding Options and Flow Server Settings

    set forwarding-options sampling input rate 10
    set forwarding-options sampling input run-length 18
    set forwarding-options sampling family inet output flow-server 10.44.4.3 port 1055
    set forwarding-options sampling family inet output flow-server 10.44.4.3 version9 template template1
    set forwarding-options sampling family inet output interface ms-2/0/0.0 source-address 203.0.113.1

    Step-by-Step Procedure

    The following example requires you to navigate through multiple levels of the configuration hierarchy.

    1. Configure the services interface.

      2. [edit interfaces] user@router1# set interfaces ms-2/0/0 unit 0 family inet
      user@router1# set interfaces ms-2/0/0 unit 1 family inet6
      user@router1# set interfaces ms-2/0/0 unit 2 family mpls

    2. Configure the template properties and the export policy timers.

      3. [edit services]
      user@router1# set flow-monitoring version9 template template1
      user@router1# set flow-monitoring version9 template template1 flow-active-timeout 120
      user@router1# set flow-monitoring version9 template template1 flow-inactive-timeout 60
      user@router1# set flow-monitoring version9 template template1 ipv4-template
      user@router1# set flow-monitoring version9 template template1 template-refresh-rate packets 100
      user@router1# set flow-monitoring version9 template template1 template-refresh-rate seconds 600
      user@router1# set flow-monitoring version9 template template1 option-refresh-rate packets 100
      user@router1# set flow-monitoring version9 template template1 option-refresh-rate seconds 600

    3. Configure service set properties.

      4. [edit services]
      user@router1# set service-set ss1 jflow-rules sampling
      user@router1# set service-set ss1 sampling-service service-interface ms-2/0/0.0

    4. Configure forwarding options and flow-server properties.

      5. [edit forwarding-options]
      user@router1# set sampling input rate 10
      user@router1# set sampling input run-length 18
      user@router1# set sampling family inet output flow-server 10.44.4.3 port 1055
      user@router1# set sampling family inet output flow-server 10.44.4.3 version9 template template1
      user@router1# set sampling family inet output interface ms-2/0/0.0 source-address 203.0.113.1

    Note: You can specify the sampling parameters either at the global level (as shown in this example) or at the FPC level by defining a sampling instance. To define a sampling instance, include the instance statement at the [edit forwarding-options sampling] hierarchy level, and the sampling-instance statement at the [edit chassis fpc number] hierarchy level to associate the sampling instance with an FPC. Under the [edit forwarding-options sampling instance instance] hierarchy level, you must also include the input and output configurations explained in this step.
