I have netflow configured on my ASA 5545 v8.6 and am receiving no information via the opFlow interface. 'show flow-export counters' show packets send to my destination IP address via udp 12345 and the netstat output from my server shows listening on 12345:udp. What am I missing?
Newer Cisco ASA, version 8 is one of them, devices are using NSEL which is like NetFlow but different enough that it called NSEL, if you can configure your ASA to send NetFlow version 5 opFlow will be able to show you the information.
