OK, I have a dumb question. When we talk about "default" encapsulation, are
we talking about an actual command? The "encapsulation" command can be
entered in Ethernet interface mode, I think. (I'm not near
n is with the ipx network
encap command.
Thanks for the interesting conversation.

but the only physical interface specified by Ethernet version 2 is 50-ohm
coax, IIRC, similar to 10base5 On 10baseT or 100baseTX interfaces, which
