PfR Data Export v1.0 NetFlow v9 Format

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.

    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

    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
