How do I configure Traffic Sentinel to receive Cisco NetFlow?
Configure the routers with a flow-export timeout active of 5 minutes or less and direct them to forward NetFlow version 1, 5, 7 or 9 to the Traffic Sentinel on UDP port 9985 (Consult your router documentation for instructions on configuring NetFlow). To change the port that Sentinel is listening on, see the NetFlowPort preference setting.
