which means that your traffic is in the format described in RFC 3332

I'm using Ethereal to display an M3UA capture session. I've found a
very weird thing analyzing a M3UA packet If I use "RFC 3332"
version to decode the packet everything is correct, but if I use
any "Internet Draft" version I get a lot "Unknown Parameters". We
did not find any difference in Payload Data Message (DATA)
parameters between those version.
You can see what I mean in the attached files.
Thank you.
