PfR Data Export v1.0 NetFlow v9 Format

The Performance Routing (PfR) Data Export v1.0 NetFlow v9 Format feature allows you to simplify real-time PfR performance data export by using the NetFlow v9 standard protocol and formats supported in RFC 3954, Cisco Systems NetFlow Services Export Version 9. It allows you to export both regular time-based performance data as well as PfR Route Policy Control Events data.

This feature exports data from the master controller (MC) to data collectors in your network and allows you to see more easily how Performance Routing is functioning in your network.

Information About PfR Data Export v1.0 NetFlow v9 Format

NetFlow Version 9 Data Export Format

NetFlow Version 9 is a flexible and extensible means for transferring NetFlow records from a network node to a collector. NetFlow Version 9 has definable record types and is self-describing for easier NetFlow Collection Engine configuration.

NetFlow Version 9 export allows new fields to be sent to the NetFlow Collection Engine (formerly called the NetFlow Collector) at set intervals. You can enable the features that you want, and the field values corresponding to those features are sent to the NetFlow Collection Engine.

Benefits of the PfR Data Export v1.0 NetFlow v9 Format Feature

The PfR Data Export v1.0 NetFlow v9 Format feature exports data from the Master Controller (MC) to data collectors in your network and allows you to see more easily how Performance Routing is functioning in your network.

Cisco customers who produce applications that provide NetFlow Collection Engine or display services for NetFlow need not recompile their applications each time a new NetFlow technology is added. Instead, with the PfR Data Export v1.0 NetFlow v9 Format features, Cisco customers can use an external data file that documents the known field types.

How to Enable the PfR Data Export v1.0 NetFlow v9 Format Feature

Enabling the PfR Data Export v1.0 NetFlow v9 Format Feature

To enable the PfR Data Export v1.0 NetFlow v9 Format feature, complete the following steps at the PfR master controller.

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    flow exporter exporter-name

    4.    destination ip-address

    5.    export-protocol netflow-v9

    6.    transport udp udp-port

    7.    exit

    8.    pfr master

    9.    exporter exporter-name

    10.    end


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 configure terminal


    Example:
    Router# configure terminal
     

    Enters global configuration mode.

     
    Step 3 flow exporter exporter-name


    Example:
    Router(config)# flow exporter pfr_exp
     

    Creates a Flexible NetFlow flow exporter and enters Flexible NetFlow flow exporter configuration mode.

     
    Step 4 destination ip-address


    Example:
    Router(config-flow-exporter)# destination 192.168.2.0
     

    Configures an export destination.

     
    Step 5 export-protocol netflow-v9


    Example:
    Router(config-flow-exporter)# export-protocol netflow-v9
     

    Configures NetFlow Version 9 as the export protocol.

     
    Step 6 transport udp udp-port


    Example:
    Router(config-flow-exporter)# transport udp 2000
     

    Configures the transport protocol.

     
    Step 7 exit


    Example:
    Router(config-flow-exporter)# exit
     

    Returns to global configuration mode.

     
    Step 8 pfr master


    Example:
    Router(config)# pfr master
     

    Enables a Cisco IOS Performance Routing (PfR) process, configures a router as a PfR master controller, and enters PfR master controller configuration mode.

     
    Step 9 exporter exporter-name


    Example:
    Router(config-pfr-mc)# exporter pfr_exp
     

    Configures a flow exporter.

     
    Step 10 end


    Example:
    Router(config-pfr-mc)# end

    Verifying the PfR Data Export v1.0 NetFlow v9 Format Configuration

    To verify the PfR Data Export v1.0 NetFlow v9 Format configuration and to ensure that the data is being exported to the master controller as expected, complete the following steps at the PfR master controller.

    SUMMARY STEPS

      1.    enable

      2.    show pfr master export statistics

      3.    show pfr master traffic-class

      4.    exit


    DETAILED STEPS
       Command or ActionPurpose
      Step 1 enable


      Example:
      Router> enable

      • Enter your password if prompted.
       
      Step 2 show pfr master export statistics


      Example:
      Router# show pfr master export statistics
       

      Displays PfR NetFlow Version 9 export statistics.

      • To clear the display, use the clear pfr master export statistics command.
       
      Step 3 show pfr master traffic-class


      Example:
      Router# show pfr master traffic-class
       

      Displays information about all the traffic classes that are monitored and controlled by at the PfR master controller.

       
      Step 4 exit


      Example:
      Router# exit
       

      Exits privileged EXEC configuration mode.
