   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.

   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.

   What is a MAC address in a network switch?

   • A network switch utilizes MAC addresses to facilitate the efficient and targeted transmission of data within a local area network (LAN). By leveraging MAC addresses, switches can intelligently manage the flow of data traffic, ensuring that packets are delivered only to their intended recipients.

   What happens when a device changes IP address and MAC address?

   • When a device changes both its IP address and MAC address, the network switch reacts by updating its address tables. The switch identifies the new MAC address as a unique device and associates it with the specific port it’s connected to.

    Sep 29, 2021 · To improve port security, you can manually add MAC address entries to the MAC address table to bind ports with MAC addresses, fending off MAC address spoofing attacks. In addition, you can configure blackhole MAC address entries to filter out packets with certain source or destination MAC addresses.
