I can't speak for that particular 3Com, but I'm using a four-port Officeconnect as an IDS hub, and it works great.Ensure they are not in fact "10/100 hubs". If so, they are actually made up of a 100M hub + a 10M hub joined via a 2-port switch. The outcome of which is that if you have (say) 3 100M Ethernet devices plugged into it, and 1 10M device, then the 3 100M devices can "see" each others traffic (like a hub allows) - but they cannot see the 10M traffic. i.e. check you Ethernet device settings and ensure they are identical - same speed and same duplex. Then see if it starts acting like a hub.
And, the exact same response can be seen from lots of not-so-cheap hubs as well. I've got a 24 port 3Com Dual Speed Superstack II that does it, just like an old Netgear 4-port dual-speed "hub". Get caught on it fairly regularily. :( Rich ------------------------------------------------------- This SF.net email is sponsored by: The SF.net Donation Program.
