It looks as though consistently 75-85% of flows get dropped with “Unknown Template” across all 20 of my Adtran Netvanta 3305’s.
My Cisco’s don’t drop any… I’ve checked AOS (Adtran software) updates and errata and nothing is mentioned about NetFlow problems… Would someone be willing to take a look at a pcap and see if the Adtran is formatting out of spec or if nTop is handling something incorrectly? Can someone recommend another NetFlow server to try out and see if it has the same problem? Any other suggestions?
