Nortel?
3Com aren't too bad. From memory Nortel are actually better at higher
throughput levels.
Nortel has a GUI Device Management system via SNMP which is pretty good.
They also have intuitive HTTP access for most things and the console gives
you a menu or a commandline option.
Look at the Nortel 5510/5520/5530 switches for Gigabit throughput...
Mark.
