* John@efirstbank.com (John Neiberger) [Fri 14 Jan 2005, 23:56 CET]:

When you hard-set these settings on the 2950, autonegotiation is completely disabled. However, many devices still participate in autonegotiation even when their settings have been set manually. They would simply only offer their manually configured settings as being available. If that type of device is manually configured for full duplex but it does not detect an autonegotiating device on the other end, it will assume that it is connected to a hub and will drop back to half duplex regardless of the configured settings.

This sounds completely crazy. Can you name vendors whose equipment performs according to this atrocity?

It sounds crazy to me for the dropping back to half duplex also, however the Thunderlan chipset in the Compaq Professional 2000 workstations would do just this - if manually configured for full duplex it will drop to half duplex if plugged into a hub that was non autonegotiating. This caused problems with many autonegotiating hubs as the card had problems figuring out if something was autonegotiating or not and often assumed autonegotiating hubs really wern't autonegotiating and would go to half duplex. Meanwhile the hub would assume the Tlan card was full duplex and setup for it.
