A MAC address is a hardware identifier. For a device on a network, it operates much the same as an email address, a house address, or a name. In a layman’s language, it’s the ID that a home network router uses to send packets of data to a specific network-connected device.

If an Alternate MAC Address was never entered, clearing it does nothing except restart the console because the field is already blank.
