We've had the same problem as well with our F740s w/ 100BT. This problem
with autonegotiation is neither particular to NetApp nor Cisco. We have
SGIs, Suns,
and HPs that also have had problems with autonegotiation, and I've heard
from
others having similar problems with other non-Cisco network devices. The
problem
is that the autonegotation standard in IEEE (Cl. 28 of IEEE 802.3u, based on
NWay
scheme) is a bit vague, which results in vendors implementing
autonegotiation
in such a way that it tends to be incompatible with how other vendors
implement
it. An unfortunate fact of life.

A good into to autonegotiation can be found at:

As for using 0.0.0.0 for the default gateway, that should be perfectly
acceptable.

I've got an Extreme Networks Black Diamond switch, and our F230 won't
auto-negotiate 100-BT-fd with that either. Of course, neither will our
Cisco 7507. It's ironic that the two more important bits on my network
won't negotiate their connection speeds, but lots of irrelevant little
workstations will.
