Wireshark · Wireshark-dev: [Wireshark-dev] Registering Dissector for Private SNAP PID

[Christopher Merck <cmerck@xxxxxxxxxxxx>]

Hi All,

 

 I wish to write a dissector for a protocol that uses an LLC SNAP header, followed by a particular OUI and PID.

 

 It seems I cannot do so in Lua because "llc.dsap" is the only dissector table registered by "packet-llc.c".

 

 I believe the correct way to proceed is to register a new dissector table along the lines of "llc.oui", then Lua dissectors may hook into that to handle particular OUIs. Perhaps this is not optimal because a dissector will then need to handle all PIDs for a single OUI. It will need to hand off the dissection down another level. So, perhaps the OUI and PID should be handled at once, something like "llc.ouipid".

 

 Any guidance is appreciated.

 

Regards,

 Chris
