What does a network switch do

Initially, the MAC Address Table of the Switch is empty. Remember, it only gets populated when a frame is received. When Host A sends the frame to the switch, it includes a Source MAC address of aaaa.aaaa.aaaa. This prompts the Switch to learn a MAC Address Table entry mapping Port 1 to MAC Address aaaa.aaaa.aaaa.
