At Layer 2 Switch?

A layer 2 switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area network (LAN).

Do switches operate at Layer 2?

As we discussed, a hub works at Layer 1 and a switch works at Layer 2. A switch will make its decisions based on the MAC addresses available in the MAC address table.

How does a Layer 2 switch work?

Within a layer 2 switch environment exists a broadcast domain. Any broadcast traffic on a switch will be forwarded out all ports with the exception of the port the broadcast packet arrived on. Broadcasts are contained in the same layer 2 segment, as they do not traverse past a layer 3 boundary.
