How do you get Netflow exports working with ASA?

[lchance]

I'm not sure this is the right forum (I tried Network Management - no response...)

We have an ASA 5540 configured with Netflow to our netflow receiver (Port 2055) but it is not receiving the ASA's netflow packets.

Does the ASA need a LOOPBACK interface to do this? Or does it have to use INSIDE or is there something else?

Thanks for any help!

Have you tried using the Cisco ASDM?  We posted this blog on how to configure NetFlow on the ASA using ASDM.  Hopefully it isn't out of date. There is also a video on viewing the NetFlow from the ASA on the plixer web site.  

Hope this helps.
