How to Configure Flexible NetFlow NetFlow V5 Export Protocol

Configuring the Flow Exporter

Perform this required task to configure the flow exporter.


Note

Each flow exporter supports only one destination.

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

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. flow exporter exporter-name
  4. description description
  5. destination {ip-address | hostname } [vrf vrf-name ]
  6. dscp dscp
  7. source interface-type interface-number
  8. output-features
  9. template data timeout seconds
  10. transport udp udp-port
  11. ttl seconds
  12. end
  13. show flow exporter exporter-name
  14. show running-config flow exporter exporter-name

DETAILED STEPS

  Command or Action Purpose
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

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 7

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 8

output-features

Example:


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

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

Step 9

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 10

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 11

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 12

end

Example:


Device(config-flow-exporter)# end

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

Step 13

show flow exporter exporter-name

Example:


Device# show flow exporter FLOW_EXPORTER-1

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

Step 14

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.
