Huh? Among other changes, I believe AppleTalk has gone IEEE 802.2 compatible, with the Ethernet address being the MAC address of the workstation, in the case that EtherTalk is being used. Previously, they used an 8 bit MAC address, and "hacked" it into working on the Ethernet. Of course other things have changed too, but I believe this is the source of your confusuion on this point. I believe that CISCO supports Ethernet MAC headers instead of IEEE 802.2 headers, with an AppleTalk type field (0x809b), and the old packet formats... > Thanks in advance to any and all that respond, Not sure it was of any assistance! > Eriks -------------------------------------------------------------------- Don Doerner dd@ariel.unm.edu 2701 Campus Blvd. NE (505)277-8036 Albuquerque, NM, 87131
