Claim:
1. A relay apparatus including at least one network side port for at least one network and at least one device side port for at least one device for reception and transmission between the at least one network and the at least one device, the relay apparatus comprising: a first memory configured to store at least one first correspondence of an output port identifier that identifies a network side transmission port among the at least one network side port to at least one first combination of a port identifier that identifies a device side reception port among the at least one device side port that received a frame among frames from the at least one device and a first communication type identifier of the received frame; a second memory configured to store at least one second correspondence of an output port identifier that identifies a device side transmission port among the at least one device side port to at least one second combination of a media access control (MAC) address and a second communication type identifier, the second correspondence being obtained by MAC address learning performed for a frame among the frames received from any of the at least one device side port; and a processor coupled to the first and second memories and the processor configured to:
