I've been playing with Linux bridging for a while, in small low-volume environments as well as with UML, without problems. However, I'm looking for something more out of a switch than I can get currently, and I was wondering if I could configure Linux to be a switch - bridge over eight or so interfaces efficently. Has anyone done this ? What sort of traffic can your average linux box handle like this ? I'm looking at using it on the NexCom boxes; http://www.ipc2u.de/servlet/comp?22785&22752&22780 which have 8 e100 nics and 4 e1000 nics on a 64bit/66Mhz bus. Seems nice, if it'll work. Then i'd need to make sure that ucd-snmp etc. will let me get traffic stats per real (not bridged) interface, just like a normal managed switch. I went through the archives of the list, and there seems to be some problems with VLANs, historically. This would be for use in a very production environment. I'll do loads of testing, but I'd like to know any caveats from day one. John
