Packets that are sent on the Ethernet are always coming from a MAC address and sent to a MAC address. For a network switch, it is likely to have many MAC addresses, since one MAC address is assigned to every interface on the switch.Ī MAC address, also known as “hardware address” or “physical address”, is a binary number used to uniquely identify computer network adapters.
