Could anyone explain why I do not see the pretty constant traffic between a remote IP camera and the backend in NetFlow cache, but I do see the icmp traffic once I ping the camera?

Hello,
1. Where are you checking netflow traffic? On the collector or on the router via show ip cache)
2. Did you enable netflow on all interfaces? If you have 6500/7600 also enable mls nde ...
Kind regards,

I'm looking both on the router and on the collector (GUI). On the router, I'm using "show ip cache verbose flow" and "show mls netflow ip [source/destination]", which show the icmp traffic as soon as I start pinging.
NetFlow is enabled on all interfaces, and in both software and hardware cache.

If I clearly understand, you are able to see icmp pings on your router but not in collector GUI. Is it correct? Could you send me output of the:
show runn | inc mls
show runn | inc flow
Thank you,

Jan,
You misunderstood. I see icmp pings (generated by myself) on both the router and the collector GUI. The problem is I don't see the alleged video traffic on either the router or the collector.
