NetFlow on L2 Switchport

kashi_login · ‎11-11-2009

Is it possible to configure NetFlow on L2 gig switchport on a multilayer switch running native IOS ?

How else can it be done and what tool can be used to view traffic visibility as seen via Netflow

Hi,

This was discussed just yesterday in the following thread:

Using the explicit cmd will i be able to export the traffic flowing through the trunk links to NetFlow Analyzer.

Yes, it is.

And nfdump is a quite good ipflow analyzer.

Can nfdump be run on windows and what cmds need to be configured on l2 switchports to forward NF packets to nfdump ?

This is link broken, or no longer available?

I'm facing the same issue right now, that was stated above. My uplink port to our router is configured as a switchport, but I would like to set this as the NetFlow destination. Is this possible?

Thanks,
