NetFlow

I have 6509 with a fiber attached 3750 attached that I want to monitor the bandwidth usage. I have read through the NetFlow and found it will do this and is supported by the 6509 but not the 3750. Does NetFlow need to be supported by the devices on both ends of the network link you are testing?

If the traffic in/out of the 3750 only goes through the 6509, you can account for the 3750's bw by enabling flow-cache on all the interfaces of the 6509.

Thanks for responding to my question.

On my 6509 I have IP routing enabled but when I go to the fiber interface that the 3750 is attached to there is no "ip route-cache flow" command.

When I am on that interface and I do a "ip ?" it show the commands RSVP, RTP and VRF as the only options available.

Is there something else I need to do to get "route-cache flow" to work?

My 6509 is at Version 12.1(22)E2.

Thanks
