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.

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： FSs (16a to 16h) are each connected to IFSs (14a to 14x). Each of the FSs (16a to 16h) transmits a setting frame (60) that includes an FS number to the connected IFSs (14a to 14x). Each of the IFSs (14a to 14x) registers, in an LAG setting table, the FS numbers included in the received setting frames (60) and ports that have received the same in association with each other. Then, each of the IFSs (14a to 14x) sorts ports (52a to 52h) in an order of the associated FS numbers, and sets each of LAGs (18a to 18x) in a common order.

摘要： A network system includes a plurality of lower switches, a plurality of upper switches, and a link group for interconnecting the plurality of lower switches to the plurality of upper switches in a multipoint-to-multipoint relationship. The link group includes a sub-link for interconnecting the plurality of lower switches to the plurality of upper switches in a point-to-point relationship as one logical link and a main link for interconnecting the plurality of lower switches to the plurality of upper switches in a point-to-multipoint relationship as one logical link. The plurality of lower switches are each set such that a broadcast frame with a broadcast address set as a destination is transmitted to the plurality of upper switches through the sub-link. The plurality of upper switches each receive the broadcast frame and resister a source address contained in the broadcast frame into an FDB of the plurality of upper switches.
