Netflow v9 on Cisco 1841

[bsciarra1]

Good morning, I am trying to use netflow version 9 on a Cisco 1841.  It works on my 2811's and 3745 but not my 1841.

Is this supported on the 1841?, it accepts my "ip flow-export version 9" and "ip flow-export x.x.x.x 9999" commands so I assume it does, am I wrong?

Hi,

Net Flow Version 9 is supported on 1841 . Let me know the configuration issue you are facing.

Here are the documents providing information about Net Flow:

Sonal, thank you for your reply.  The 1841 is our internet router and it's on the other side of our firewall.  It turns out the problem I am facing is not the 1841 or the netflow config, but there is something wrong with my Netflow policy on my firewall.  Trying to open for udp port 9999, but for some reason not working.  It's a firebox, not ASA, I have to work with Firebox support to get it corrected.  Thanks again....
