I have a computer (windows machine) that I want to run netflow on. The computer is connected to a switch with port mirroring such that all traffic from all ports get mirrored to that computer with netflow... I installed ManageEngine Netflow analyzer on that computer and tested it by sending random traffic to port 9996 but unfortunately nothing got captured. Can someone please help me with this? does this app generate netflow records for raw traffic sent to the port it's using for listening?

Here is what I see when I open the dashboard:

No device is currently exporting NetFlow / sFlow packets to NetFlow Analyzer.  Listening for NetFlow / sFlow Packets at Port 9996  Click here for instructions to enable NetFlow / sFlow Exports on the router / switch.  Click here to add devices configured with QoS policies

Thanks!
