Reporting Extracted Fields Through Flexible NetFlow

Reporting Extracted Fields Through Flexible NetFlow

The Reporting Extracted Fields Through Flexible NetFlow feature allows Network-Based Application Recognition (NBAR) to send subapplication table fields to the collector through Flexible NetFlow.

Information About Reporting Extracted Fields Through Flexible NetFlow

Subapplication Table Fields

Use the option sub-application-table command to send an options table periodically to the collector, thereby enabling the collector to map NBAR subapplication tags, subapplication names, and subapplication descriptions provided in the flow records to application IDs.

How to Report Extracted Fields Through Flexible NetFlow

Reporting Subapplication Table Fields

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    flow exporter exporter-name

    4.    option sub-application-table

    5.    exit


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Device> enable
              
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.

     
    Step 2configure terminal


    Example:
    Device# configure terminal            
              
     

    Enters global configuration mode.

     
    Step 3flow exporter exporter-name


    Example:
    Device(config)# flow exporter EXPORTER-1            
              
     

    Enters Flexible NetFlow flow exporter configuration mode.

     
    Step 4option sub-application-table


    Example:
    Device(config-flow-exporter)# option sub-application-table            
              
     

    Enables periodic sending of an options table that allows the collector to map NBAR subapplication tags, subapplication names, and subapplication descriptions provided in flow records to application IDs.

     
    Step 5 exit


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

    Exits Flexible NetFlow flow exporter configuration mode and returns to global configuration mode.

     

    Configuration Examples for Reporting Extracted Fields Through Flexible NetFlow

    Example: Reporting Subapplication Fields

    The following example shows how to enable the periodic sending of an options table, which allows the collector to map NBAR subapplication tags, subapplication names, and subapplication descriptions provided in the flow records to application IDs:

    Device(config)# flow exporter FLOW-EXPORTER-1
    Device(config-flow-exporter)# option sub-application-table
