Layer 3 switches can be configured to consider 2 physically :adjacent ports to be on completely different networks; they will not even :share broadcast traffic. If you shop carefully, you can even buy switches :where you can configure VLANs based on user authentication, any given :physical port can join a VLAN based on a user login program rather than :port number or MAC or IP address. : :Wes Peters Softweyr LLC :http://softweyr.com/ wes@softweyr.com I would *never* *ever* configure a switch with dynamic VLANs. Not even if my life depended on it. It would be impossible to track down problems. It's hard enough keeping the network topology straight with statically configured VLANs. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
