How does a switch know if a frame is broadcast, multicast or unicast? In this type of communication, there is only one sender that sends data frame to one connected receiver. Unicast is the term used to describe communication where a frame is sent from one end point to the only one end point. In this type of communication, there is only one sender that sends data frame to one or multiple connected receivers. Multicast is the term used to describe communication where a frame is sent from one end point to one or multiple end points at the same time. In this type of communication, there is only one sender that sends data frames to all connected receivers. Broadcast Frameīroadcast is the term used to describe communication where a frame is sent from one end point to all other end points at the same time.

What is broadcast, multicast, unicast and how does it work? Even if you disconnect every end point from the network, there will still be an infinite broadcast and multicast storm between both switches. The broadcast or multicast frames created by any end point in the network will be received by the switches and flooded out of every port except the port that the frame was received on, creating a layer 2 loop between two switches. Imagine that Layer 2 loop prevention mechanism is not enabled or is broken on the switches somehow. Consider the figure below, in which two switches are connected to each other with multiple path.
