NetFlow Receiver Service received an invalid V9 template Cisco ASA

Hello,

Since upgrading our Cisco ASAs from 8.2 to 9.1(3) NTA is not able to process the netflow it's receiving. We're running NTA v3.9 and receive the above error from all of our sources except an old ASA running 8.2

I can see the packets arriving at the netflow collector. Is there anything I need to do in order to allow the collector to process the netflow it's receiving?

Hello,

NTA requires some fields to be present in flows. You can see this article for reference. Check this in WireShark or post a screenshot from WireShark showing NetFlow v9 template. If you confirm all required fields are present and still no flows are being processed I suggest to open support ticket.

Regards,

Martin

our new NTA 4.1.1 beta has also some improvements for ASA devices and templates. once you check the required field let us know back.
