1. A relay system comprising:
a first switching device and a second switching device each having a plurality of ports including a bridge port and a MCLAG port on which an inter-device LAG is set, the first switching device and the second switching device being connected to each other by a communication line via the bridge ports, wherein the first switching device or the second switching device has a first port on which an inter-device LAG is not set as the plurality of ports, each of the first switching device and the second switching device includes: an address table which retains a correspondence relation between a port identifier representing the port or a MCLAG identifier associated with the MCLAG port and a MAC address; a relay processing unit which, when a frame is received at the port, relays the frame based on the address table; a MCLAG learning frame transmitting unit which, when a frame is received at the MCLAG port, generates a MCLAG learning frame containing a source MAC address of the frame and the MCLAG identifier and when a frame is received at the first port, generates a MCLAG learning frame containing the source MAC address of the frame, and transmits the generated MCLAG learning frame from the bridge port to a peer device; and a MCLAG learning frame receiving unit which, when the MCLAG learning frame from a peer device is received at the bridge port and the MCLAG learning frame contains the MCLAG identifier and the source MAC address, learns a first correspondence relation between the MCLAG identifier and the source MAC address to the address table, and when the MCLAG learning frame contains the source MAC address and does not contain the MCLAG identifier, learns a second correspondence relation between a port identifier of the bridge port and the source MAC address to the address table. |
