Sorry to add to any confusion, I probably should not have used "hub" as an example. I usually think of hubs as fairly intelligent repeaters. That type of device typically knows a thing or two about the link layer. However, something like a passive hub definately lives its whole existence on the physical layer. But a "switched hub" obviously knows all about the link layer. The term "hub" is used to describe several categories of hardware in every-day usage. -- Crist J.
