Performance Routing Configuration Guide, Cisco IOS XE Release 3S

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 Action Purpose
Step 1 enable


Example:
Router> enable

  • 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

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 
 

Exits PfR master controller configuration mode and returns to privileged EXEC mode.

 

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 Action Purpose
Step 1 enable


Example:
Router> enable
 

Enables privileged EXEC mode.

  • 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.

 

Configuration Examples for the PfR Data Export v1.0 NetFlow v9 Format Feature

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

The following example shows how to enable the PfR Data Export v1.0 NetFlow v9 Format feature at the PfR master controller.

Router> enable
Router> configure terminal
Router(config)# flow exporter pfr_exp
Router(config-flow-exporter)# destination 192.168.2.0
Router(config-flow-exporter)# export-protocol netflow-v9
Router(config-flow-exporter)# transport udp 2000
Router(config-flow-exporter)# exit
Router(config)# pfr master
Router(config-pfr-mc)# exporter pfr_exp
Router(config-pfr-mc)# 

The following is sample output of the show pfr master export statistics command when the PfR Data Export v1.0 NetFlow v9 Format feature is enabled.

Router# show pfr master export statistics
