I do not know; the machine is hundreds of miles away and remote hands are
difficult to arrange.  I haven't tried the second interface with this
switch nor tried any other GE switches.  When I installed netbsd, it was
connected to a 10/100 cisco.  It worked fine, but I do not recall if it
negotiated full-duplex or not.

If I watch the switch and machine closely (repeat the commands), they
seem to agree on 1000/FD, then reset, repeat.
