is there anything appearing in netflow with field type 128 or 129?  There
are two possible ASN fields for netflowv9: the older fields from the
original netflowv9 spec:

but also the newer IDs taken from ipfix:

You may need to explicitly enable support for this in nfcapd using the "-T
all" or "-T 15" command-line parameter.
