(i.e. 20 sec = negotiation time) Autoneg must be completed within 2 sec, or else it is considered as failed.
It should be pointed out that there is a difference between completing autonegotation and being able to pass traffic to other devices in the network. The spanning tree and port fast settings have nothing to do with autonegotiation. With port fast disabled on these switches, autonegotation usually completes in the required 2s, but the switch does not pass frames to the rest of the network until spanning tree assures loop free topology. The NIC and switch port are actively passing traffic, but the switch is not forwarding that traffic.
Hope this helps clarify.
