Relay system and switching device

摘要

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.

1. A relay system, comprising:
a plurality of port switches; and a plurality of fabric switches functioning to relay a frame between the plurality of port switches, wherein each of the plurality of port switches is connected to each of the plurality of fabric switches by links, each of the plurality of fabric switches is configured to: detect a fault of links connected to itself; when a fault is detected, generate a first fault notification frame containing a fault link identifier representing a link having the fault; and transmit the first fault notification frame to the plurality of port switches, and flood a second fault notification frame when the second fault notification frame is received from any of the plurality of port switches, each of the plurality of port switches is configured to: detect a fault of links connected to itself; when a fault is detected, generate the second fault notification frame containing a fault link identifier representing a link having the fault; transmit the second fault notification frame to the plurality of fabric switches; and when the first fault notification frame or the second fault notification frame is received at all of links connected to itself, set LAG to the links connected to itself based on the fault link identifier contained in the received fault notification frame.
