Layer 2 vs layer 3

A Layer 3 switch -- also referred to as a multilayer switch -- combines the duties of a switch and a router. It acts as a switch because it connects devices that are on the same IP subnet or virtual LAN, and it performs at or near wire speed. But it also acts as a router because it has IP routing intelligence built in.
