Not sure exactly why this is... maybe it's >a function of the general amount of traffic. I've found the 3C595 requires a reboot for autodetect to change from 10 -> 100 and vice versa. The Intel Pro 100B can do this on the fly from 10 -> 100 or 10 -> 100 duplex and back. This was was with a Intel 3205 switch, so it may have been that they played nicer together, but the 3C595 would not change on the fly with a 3Com switch. This also worked with a cross cable and was the same for FBSD and NT/95 (amazingly). And I expected to reboot.
