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
