Abstract
One embodiment disclosed relates to a method of fault recovery by a switch in a local area network. A link failure is detected at a port of the switch. In response to the link failure detection, a MAC address table of the switch is cleared. Clearing the address table causes a discovery process to fill the table to begin immediately. In addition, a link on another port of the switch may be dropped to propagate the link failure.
