Learning function: The Ethernet switch learns the MAC address of the device connected to each port, maps the address with the corresponding port, and stores it in the MAC address table in the switch cache.
Forwarding filtering: When the destination address of a data frame is mapped in the MAC address table, it is forwarded to the ports connected to the destination node instead of all ports (or to all ports if the data frame is a broadcast/multicast frame).
Eliminate loops: When a switch includes a redundant loop, the Ethernet switch avoids loops through a spanning tree protocol while allowing for a fallback path.
Refresher: The Ethernet AC machine tastes the MAC address of the device connected to each port, and maps the address to the responding port and stores it in the MAC address table in the AC cache.
Forwarding/Filtering: When the destination address of a data frame is mapped in the MAC address table, it is forwarded to the ports of the destination node adjacent to it instead of all ports (or to all ports if the data frame is a broadcast/multicast frame).
