Try it. Ethernet is based on physical and data layer characteristics with a
strong dose of CSMA/CD. If all sides agree what the bit times will be above
64 then it might work. The mtu command could probably be placed on all
interfaces involved.
On another note, I remember having two identical servers-one fast ethernet,
the other with a 100Mbs ATM card hooked directly to an ATM switch and the
server with the ATM card always seemed "faster" than the one with the FE
card. This was a production environment so I never really got a chance to do
any real testing. I have always felt that the predictabilty of the ATM cell
sizes would account for the seemingly faster throughput. We have moved away
from ATM on the LAN to Gig except for some WAN connections so I might never
know.
Let us know if it worked.

Subject: Fast Ethernet MTU Size
Hi All,
Is it at all possible to raise the MTU size on Fast Ethernet?
I'll give you all a scenario....
ATM on one side with an MTU of 4470, fast ethernet connecting the two
routers, Gigabit Ethernet the other side with an MTU of 4470.
How can I raise the MTU of a Full Duplex Fast Ethernet Connection above
1500?
I assume it's not possible when going through switched as they will show
every packet as a giant but in a router to router cross-over connection
I was hoping there was some way to keep the MTU static across the path
rather than force the routers to fragment and re-assemble (of course the
destination re-assembles).
