Abstract
The apparatus stores a manual flag having a stored manual flag logic value, and the manual flag is stored in a first non-volatile memory. The apparatus stores a trusted flag having a stored trusted flag logic value, and the trusted flag is stored in a second non-volatile memory. The apparatus is connected to a computer network for performing a first boot-up operation. The apparatus learns an address of a neighbor apparatus connected through the communications network. The apparatus is responsive: to the manual flag, and to the trusted flag, and to the first boot-up operation, and to learning a neighbor address of the neighbor apparatus, for configuring an address of the apparatus from an identifier stored in a third non-volatile memory, and from the neighbor address, and for changing the stored trusted flag logic value to a second logic value. Also the apparatus chooses, responsive to the manual flag, between using a manually loaded address or performing the configuring an address. Additionally, the apparatus decides, responsive to a neighbor trusted flag learned by communicating with the neighbor apparatus through the communications network, to use the neighbor address of the neighbor apparatus in configuring an address of the apparatus.
