This can be done both on switches and routers. On Cisco routers you would use a route-map to basically copy all traffic passing through one interface to another interface. Possible uses would be for IDS setups and probably other uses. On switches it would be known as port mirroring.

Just to clarify, I'm pretty sure you're talking about switches that have
a "mirror" port.
