ABSTRACT:
Methods and apparatus are disclosed for conveying link state information between ports of a network switch. A switch may be configured to detect whether a link associated with a port of the switch has changed state. If the link has been found to have changed state, such as when the link has failed, this information is conveyed to other ports of the switch. In a preferred embodiment, other links may be reset or flapped in response to such a detection.
