Hi.

I have started to monitor our Token-Ring traffic in addition
to the ethernet, and in the process I have had start modifying
tcpdump for recognising 802.2 frames. SNAP-frames seems quite
easy, but there are some other frames on the net I can`t find
out what they are. Most of them have a DSAP and SSAP that has
a value of 'E0'. That is - the first two bytes in the 802.2
frame are E0E0. I have read RFC1340, which has a list off known
DSAPs and SSAPs, and 'E0' is not one of them. Anybody able to
help me ?
