Netflow on cisco switches

[q-le]

Hi All,

We want to start using Netflow to monitor traffic and wonder how to find out if our access switches ie a mix of 3750s and 2960s can handle

NetFlow and is there a template or sample configuration we can use.

Any help is much appreciated.

Thanks

You need a 3750-X with a service module for Netflow suppport.

The 2960 does not support Netflow that I am aware of.

Daniel,

Is it correct that you need IPservice IOS to have NetFlow?

Can we run it from our Nexus 7000 core since our access switch are older gen 3750.

Cheers,
