How can I map SAP x0c8 to SNA protocol ?

0

Per wireshark - Internals - Dissector tables - Integer tables SNA dissector is being called for LLC SAP 4, 8 12, 64 only.

There are some SNA stacks that receive SNA NLP frames on DSAP 0xc8.

Here is a sample capture file showing SNA NLP traffic in both directions.

sna_nlp.sap_c8.pcapng

Can the 0xC8/200 SAP value be included for SAP dissection ?

How can I dissect those frames using LUA (being a LUA script layman) ?

Thanks and regards Matthias

If it's not a user settable item, it should go through the Wireshark bug system. You can file an enhancement bug there, and please attach the sample capture as well. This makes development and test much easier. If it's a simple change as it seems to be, it could be quickly implemented.
