Hello,

I am trying to process the output of tshark so that it displays the SNMP
fields that I need and only them.
If I use 
$ tshark -V -R snmp -r myfile.pcap
then I get far too much information, but I also realize that quite a
number of PDUs have multiple OIDs in them.

However, when I start filtering with for instance this:
$ tshark -R snmp -r myfile.pcap -Tfields -e frame.number -e snmp.name
I am only seeing the last OID of each packet.



Example:

********************************************************************

I have tried many of the snmp.* fields, none of them gave me the full
list of OIDs that are present in the PDU. Is it a lost cause?
