   How does a network switch learn MAC addresses?

   • A network switch learns MAC addresses through a process known as “MAC learning.” When a data packet arrives at a switch port, the switch examines the packet’s source MAC address. If the address is not already present in the MAC address table, the switch adds it, associating it with the port where the packet arrived.

   How does a network switch handle dynamic MAC addresses?

   • A network switch handles dynamic MAC addresses based on its MAC address learning function. In general scenarios, when a device connects to a switch port, the switch learns the device’s MAC address and updates its MAC address table accordingly. If a device disconnects or if its MAC address changes, the switch updates the table to reflect the change.

   What is a MAC address?

   • A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) for communications at the data link layer of a network segment. The network switch, a critical component in local area networks (LANs), employs MAC addresses to efficiently manage the flow of data between devices connected to its ports.

   superuser.com › questions › 1767903

   Feb 10, 2023 · It seems that MAC addresses are used to do an IP-MAC mapping inside a switch in a LAN, but it seems redundant since the switch already should know which port leads to which host with a given IP address.

   Sep 15, 2018 · MAC address (Layer 2) is what hosts use to communicate on LAN on the same network . If hosts are in the same switch (as you've said) basically you don't have routers (Layer 3) in between them which uses an IP address to distinguish a hosts on the network.
