In order to Support Cisco ASA Device NFA 9.2.1 will now support new NetFlow fields.
The main change is that ASA Devices use bidirectional fields for Octets/Bytes.
Below are the new required NetFlow Fields for NFA 9.2.1:
One of the following: 1 - IN_BYTES, 85 - IN_PERMANENT_BYTES, 231 - For ASA devices we need both FW_INITIATOR_OCTETS, and 232 - FW_RESPONDER_OCTETS
4 - PROTOCOL
7 - L4_SRC_PORT
8 - IPV4_SRC_ADDR
10 - INPUT_SNMP
11 - L4_DST_PORT
12 - IPV4_DST_ADDR
14 - OUTPUT_SNMP
You can still use Wireshark to capture and decode the NetFlow to see if you have the required fields as shown in the Tech Tip below:
