WebNov 14, 2014 · When a frame is received, the switch compares the SOURCE MAC address to the MAC address table. If the SOURCE is unknown, the switch adds it to the table along with the physical port number the frame was received on. In this way, the switch learns the MAC address and physical connection port of every transmitting device. WebMar 6, 2024 · There are several types of Ethernet frames: Ethernet II frame, or Ethernet Version 2, [lower-alpha 6] or DIX frame is the most common type in use today, as it is often used directly by the Internet Protocol.
