Anyone know what the following ethernet type fields are and what they are used
for?
001a -> seen from a Cisco Gateway -- dst is a multicast address
(one packet about every 60-90 seconds)
7000 -> seen from a UB XNS terminal server -- dst is both a multicast
address and a specific machine
7002 -> seen from a UB XNS terminal server -- dst is a multicast address
7030 -> seen from a Proteon Gateway -- src & dst address are the same
(one packet about every 4 seconds)
As far as this one goes, I was told that the ethernet board
of the Proteon is set up to do this (the Proteon has
nothing to do this transmission) as a test, though I
don't see how because the dst address is the SAME as
the src address.
Thanks in advance

The "protocol" is in the 802.2 LLC header following the 802.3 MAC header.
