Abstract
When a fabric switch detects a fault in its own link, the fabric switch transmits a first fault notification frame containing a fault link identifier representing the detected fault to a plurality of port switches. When the fabric switch receives a second fault notification frame from a plurality of port switches, it floods the second fault notification frame. When a port switch detects a fault in its own link, it transmits a second fault notification frame containing a fault link identifier to the plurality of fabric switches. Also, when the port switch receives the fault notification frame at all of its own links, it sets the LAG based on the fault link identifier.
