Is a switch a Layer 2 device?

Switches are one of the traffic directors on the network, and traditionally operate at Layer 2 . They allow for the connection of multiple devices in a LAN while decreasing the collision domain by employing packet switching.18 Şub 2022

Layer 2 switches They interconnect networks at layer 2, most commonly at the MAC sublayer, and operate as bridges, building tables for the transfer of frames among networks .

The layer 2 and Layer 3 differs mainly in the routing function. A Layer 2 switch works with MAC addresses only and does not care about IP address or any items of higher layers . Layer 3 switch, or multilayer switch, can do all the job of a layer 2 switch and additional static routing and dynamic routing as well.6 Eki 2021

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).
