摘要： A network relay system (10) includes a plurality of IFSs (14) and a plurality of FSs (16). The IFSs (14a to 14x) are each connected to the FSs (16a to 16h) through physical lines. In the IFSs (14), an LAG is set for ports connected to the FSs (16). The IFSs (14) and the FSs (16) transmit/receive a detection frame to/from each other, and when the detection frame fails to be received, it is determined that a failure has occurred within the network relay system (10). When one of the FSs (16) determines that a failure has occurred, the one of the FSs (16) transmits a failure notification frame to the plurality of IFSs (14), and each of the plurality of IFSs (14) excludes the port that has received the failure notification frame from the LAG.

摘要： A network system includes lower switches and upper switches connected to the lower switches. Each of the upper switches transmits a first notification frame containing a connected lower switch number information indicative of the number of the lower switches connected to each of the upper switches, to the lower switches connected to each of the upper switches. Each of the lower switches configures a link aggregation group for ports which received the first notification frames each of which contains a maximum value of the connected lower switch number information among the connected lower switch number informations contained in the received first notification frames.
