We just installed a Cisco Wireless Controller 5508, and set it up to export Netflow v9.
From the Controller, we see the flows are exported correctly :
"Exporter-name: PRTG2 Total Flows Sent: 6300 Total Pkts Sent: 342 Total Pkts Dropped: 0 "
And on the PRTG server, on Wireshark, we can see the flows coming in.
But yet , we still get "No data since startup" on the Netflow Custom sensor.
We have setup other Netflow v9 sensors, from other Cisco routers without any problems.
Any idea what could I be doing wrong ?
