Step 1 To access the router’s NetFlow page, do one of the following:

•(Device view) Select Platform > Logging > NetFlow from the Policy selector.

of the fields on this page.

Step 2 On the Setup tab of the NetFlow page, specify global NetFlow parameters for the router:

and to specify how the primary NetFlow collector will be defined. You can choose the blank entry

to disable this option.

–

IP Address – Enter the IP address of the device hosting the primary NetFlow Collection Engine,

and then enter the number of the UDP Port monitored by that flow collector (port numbers can

range from 1 to 65535)

–

Hostname – Enter the fully qualified domain name of the device hosting the primary NetFlow

Collection Engine, and then enter the number of the UDP Port monitored by that flow collector

(port numbers can range from 1 to 65535)

•Redundant Destination – Choose IP Address or Hostname from this list to specify how the back-up

NetFlow collector will be defined. You can choose the blank entry to disable this option.

–

IP Address – Enter the IP address of the device hosting the secondary NetFlow Collection

Engine, and then enter the number of the UDP Port monitored by that flow collector (port

numbers can range from 1 to 65535)

–

Hostname – Enter the fully qualified domain name of the device hosting the secondary NetFlow

Collection Engine, and then enter the number of the UDP Port monitored by that flow collector

(port numbers can range from 1 to 65535)

Note If you define a Primary and a Redundant Destination, flow data is transmitted to both.

•Source Interface – Specify the router interface through which flow data will be transmitted to the

collector destination(s).
