It should be noted that this usually isn't recommened. Dropping an ethernet circuit directly into a switch (even if it is laywer 3) can create design issues, esecially later when you need to scale the network. One big issue that is often overlooked is many swithces do not support traffic shaping. Some support policing, but shaping can be far more efficient. There are some nortel switches that do this, but I haven't seen many in the wild.

Also, if you are plugging in a lower-speed link, you can plug ethernet in a <$1000 switch and trunk it to a router, while a mux for T1/T3/OCx circuits costs a lot more. -- Chris Adams <cmad...@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
