MAC Address
In a computer network such as a local area network (LAN), the MAC
(Media Access Control) address is a unique computer hardware
number. For a connection to the Internet, a table is used to convert the
assigned IP number to the hardware’s MAC address.
In order to guarantee that the MAC address is unique, all addresses are
managed in a central location. PHYTEC has acquired a pool of MAC
addresses. The MAC address of the phyCORE-MCF548x is located
on the bar code sticker attached to the module. This number is a
12-position HEX value.
