Abstract:
MAC addresses of information devices on a network are collected using a broadcast frame or multicast frame of Ethernet®. If duplicate MAC addresses are detected, an Ethernet® frame, including a device identifier of information device and a MAC address to be set, is sent by broadcast transmission or multicast transmission. The information devices receiving this Ethernet® frame compare the above device identifier with their own device identifiers. If they match, the MAC address is changed to that designated. Duplicate MAC addresses are thus resolved, enabling correct Ethernet® communications.
