Yes, I've configured cflowd on a 7750 SR12 R14 and Solarwinds NTA (3.10.0).....but I can't say that it's working. I believe that cflowd is pushing the right data, but NTA seems to be oblivious.
Well, i had a session today with solarwinds tech support, since I'm testing it to buy on an big geographical level.
Turns out Solarwinds doesn't work with cflow. Sflow/Jflow and many others, but not cflow.
I wonder when are we going to have sflow on 7210 and 7750
