ABSTRACT:
A relay apparatus includes a MAC (Media Access Control) address learning table for recording transfer destinations for frames. The relay apparatus is connected to other relay apparatuses to compose a network of a ring redundancy method. The relay apparatus includes a port move detecting circuit for detecting a port move which occurs in a case where a frame arrives from other than a path learned in the MAC address learning table on a path changing on ring redundancy.
