NetFlow on L2 Switchport

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

Re: NetFlow on L2 Switchport

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

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,

C
