Information About Flexible Netflow Export to an IPv6 Address

Flexible Netflow Export to an IPv6 Address Overview

This feature enables Flexible NetFlow to export data to a destination using an IPv6 address.

How to Configure Flexible Netflow Export to an IPv6 Address

Configuring the Flow Exporter

Perform this required task to configure the flow exporter.


Note

Each flow exporter supports only one destination. If you want to export the data to multiple destinations, you must configure multiple flow exporters and assign them to the flow monitor.

You can export to a destination using either an IPv4 or IPv6 address.

    16.    show running-config flow exporter exporter-name


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Device> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 configure terminal


    Example:
    Device# configure terminal
     

    Enters global configuration mode.

     
    Step 3 flow exporter exporter-name


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

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

    • This command also allows you to modify an existing flow exporter.
     
    Step 4 description description


    Example:
    Device(config-flow-exporter)# description Exports to the datacenter
     

    (Optional) Configures a description to the exporter that will appear in the configuration and the display of the show flow exporter command.

     
    Step 5 destination {ip-address | hostname} [vrf vrf-name]


    Example:
    Device(config-flow-exporter)# destination 172.16.10.2
     

    Specifies the IP address or hostname of the destination system for the exporter.

    Note   

    You can export to a destination using either an IPv4 or IPv6 address.

     
    Step 6 export-protocol {netflow-v5 | netflow-v9 | ipfix}


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

    Specifies the version of the NetFlow export protocol used by the exporter. The export of extracted fields from NBAR is supported only over IPFIX.

    • Default: netflow-v9.
     
    Step 7 dscp dscp


    Example:
    Device(config-flow-exporter)# dscp 63
     

    (Optional) Configures differentiated services code point (DSCP) parameters for datagrams sent by the exporter.

    • The range for the dscp argument is from 0 to 63. Default: 0.
     
    Step 8 source interface-type interface-number


    Example:
    Device(config-flow-exporter)# source ethernet 0/0
     

    (Optional) Specifies the local interface from which the exporter will use the IP address as the source IP address for exported datagrams.

     
    Step 9 option {exporter-stats | interface-table | sampler-table | vrf-table} [timeout seconds]


    Example:
    Device(config-flow-exporter)# option exporter-stats timeout 120
     

    (Optional) Configures options data parameters for the exporter.

    • You can configure all three options concurrently.
    • The range for the seconds argument is 1 to 86,400. Default: 600.
     
    Step 10 output-features


    Example:
    Device(config-flow-exporter)# output-features
     

    (Optional) Enables sending export packets using quality of service (QoS) and encryption.

     
    Step 11 template data timeout seconds


    Example:
    Device(config-flow-exporter)# template data timeout 120
     

    (Optional) Configures resending of templates based on a timeout.

    • The range for the seconds argument is 1 to 86400 (86400 seconds = 24 hours).
     
    Step 12 transport udp udp-port


    Example:
    Device(config-flow-exporter)# transport udp 650
     

    Specifies the UDP port on which the destination system is listening for exported datagrams.

    • The range for the udp-port argument is from 1 to 65536.
     
    Step 13 ttl seconds


    Example:
    Device(config-flow-exporter)# ttl 15
     

    (Optional) Configures the time-to-live (TTL) value for datagrams sent by the exporter.

    • The range for the seconds argument is from 1 to 255.
     
    Step 14 end


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

    Exits flow exporter configuration mode and returns to privileged EXEC mode.

     
    Step 15 show flow exporter exporter-name


    Example:
    Device# show flow exporter FLOW_EXPORTER-1
     

    (Optional) Displays the current status of the specified flow exporter.

     
    Step 16 show running-config flow exporter exporter-name


    Example:
    Device# show running-config flow exporter FLOW_EXPORTER-1
     

    (Optional) Displays the configuration of the specified flow exporter.
