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.

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