Routers and Layer 3 Switching. While most switches operate at the Data layer (Layer 2) of the OSI Reference Model, some incorporate features of a router and operate at the Network layer (Layer 3) as well. In fact, a Layer 3 switch is incredibly similar to a router.
In the Open Systems Interconnection (OSI) communications model, a switch performs the Layer 2 or Data-link layer function. That is, it simply looks at each packet or data unit and determines from a physical address (the MAC address) which device a data unit is intended for and switches it out toward that device.n a wide area packet-switched network such as the Internet, a switch determines from the IP address in each packet which output port to use for the next part of its trip to the intended destination.
