Please note that due to vagaries in the auto-negotiation spec 3com and cisco dont work well together. And 3coms ( on linux atleast ) have the added bonus of sometimes deciding to change speed/duplex just for the heck of it. The only way to use them reliably is to force both the card and the switch. We came to the conclusion that fxp's are a nicer option. IMHO just creating a reliable and clearly defined auto-negotiation protocol will do more for ethernet speed than gigabit ethernet :). -- Sten Spans "What does one do with ones money, when there is no more empty rackspace ?"
