This doesn't sound like an autonegotiation issue but more like a
If you are shure that this port is only used for a host connection and
not to connect
other switches (so no loops can happen), you can turn off spanning tree
for that switch-
interface bye setting "spanning-tree portfast" (Cisco IOS) for this
interface. The whole
spanning tree process for a switch interface takes about 55 seconds
default spanning tree parameters), so you can save a lot of time here.
