How does a network switch use a mac address? A switch builds its MAC address table by recording the MAC address of each device connected to each of its ports. The switch uses the information in the MAC address table to send frames destined for a specific device out the port, which has been assigned to that device.

How does a switch learn a MAC address of an attached host? A switch can learn MAC address in two ways; statically or dynamically.

The switch stores the CAM table in the RAM.
