Configuring NetFlow Input Filters for Traffic Class Reporting

IOS versions 12.2(25)S, 12.2(27)SBC and 12.3(4)T and greater support the NetFlow Input Filters feature, which can be used by NetFlow Tracker to report upon the traffic class used to route each flow.

flow-sampler-map allflows mode random one-out-of 1 exit

Create a flow sampler that exports every flow record.

policy-map netflowpolicymap class <class> netflow-sampler allflows exit

exit

Create a policy map containing NetFlow sampling actions; you must include each class that you would like information on.

interface <interface>

service-policy input netflowpolicymap

exit

Associate the policy map with an interface; you must associate the policy map with each NetFlow-enabled interface that you would like traffic class information from.

Enabling Flow Detail Records on a Packeteer Device

A Packeteer 1200, 1550, 2500, 4500, 6500, 8500, 9500, or 10000 series running PacketWise v7.0.0 or above and having 256MB or more of memory can be configured to send either NetFlow records or a similar proprietary format to NetFlow Tracker. For more information visit http://support.packeteer.com/documentation/packetguide/rc3.1/overviews/flowde tail.htm

To enable Flow Detail Records, first log in to the PacketShaper in touch mode, then open the “flow detail records” page on the “setup” tab. In one of the collector rows, enter the IP address of the NetFlow Tracker server and one of the ports configured in the Listener Ports settings page (2055 is monitored by default). Packeteer-1 is the recommended record type for use with NetFlow Tracker; Packeteer-2 is also supported but NetFlow Tracker does not use any of the extra information and thus it is wasteful of network bandwidth between the PacketShaper and the NetFlow Tracker server. You can also choose to export NetFlow v5 records; this will prevent the Traffic Classes and Identified Applications reports and filters from functioning for the device. Finally, set the value under “Enabled” to “on” and click “apply changes…”.
