  • Why do switches need to support so many MAC addresses?

    Switches are unlike hubs or repeaters. A hub simply rebroadcasts every signal on every port to every other port, which (while inefficient and slow) is easy to create. A switch, on the other hand, intelligently directs traffic between systems by routing packets only to their proper destination.
