I think someone just opened a case for this and I took a look at the pcap.
The pcap is showing the following fields:
SrcAddress
DstAddress
SrcPort
DstPort
Protocol
Packets
Octets
However it does not have inputint(input_snmp) or outputint(output_snmp) which currently are required to map data to input interfaces and output interfaces which is why NFA will drop the flows.
You can see if the flow data has the required fields by following this document: https://comm.support.ca.com/kb/How-can-I-determine-if-a-NetFlow-enabled-device-is-sending-the-correct-fields-and-data-using-WireShark/KB000011095
This is similar to Cisco WLC devices which also are missing those fields and we currently do not support yet, and there have been several Ideas open in the communities for this.
I have made Product Management aware of this and I am hopeful support for these types of devices can be added in the future.
