METHOD OF RESTORING A MAC ADDRESS AND RECORDING MEDIUM

摘要

A method of restoring a MAC address in system, the method includes, first transmitting a first frame, in which a origin of a transmission is a first MAC address held in the administration target machine, to the administration server, admitting a passage of a frame, in which the origin of the transmission is a MAC address included in a permission list, second transmitting a second frame, in which the origin of a transmission is the second MAC address, to the administration server, when not receiving a reply for the first frame from the administration server, replying a third frame which includes the regular first MAC address corresponding to the second MAC address, and restoring the first MAC address to the regular first MAC address included in the third frame and re-starting based on the first MAC address after restoration.

1. A method of restoring a MAC address in system that a plurality of administration target machines connects with an administration server through a network communication device, the method comprising:
first transmitting a first frame, in which a origin of a transmission is a first MAC address held in the administration target machine, to the administration server, which stores a regular first MAC address corresponding to a second MAC address, by the administration target machine, through the network communication device; admitting a passage of a frame, in which the origin of the transmission is a MAC address included in a permission list which stores the regular first MAC address dynamically assigned to the administration target machine and the second MAC address uniquely assigned to the administration target machine for each of the plurality of administration target machines, by the network communication device; second transmitting a second frame, in which the origin of a transmission is the second MAC address held in the administration target machine, to the administration server, when not receiving a reply for the first frame from the administration server, by the administration target machine; replying a third frame which includes the regular first MAC address corresponding to the second MAC address in response to the second frame by the administration server; and restoring the first MAC address to the regular first MAC address included in the third frame in response to the third frame and re-starting based on the first MAC address after restoration by the administration target machine.
