Media Access Control address: this is a hardware address that uniquely identies each
node of a network
With the MAC address eld, you can assign the Cortexa 7202 a MAC address, which is a
12-digit code assigned to a unique piece of hardware for identication. Some ISPs require
that you register the MAC address of your network adapter that is connected to your cable
or DSL modem.
Therefore, in order to connect the Cortexa 7202 to your cable or DSL modem instead of
the PC (network card or adapter), you must change the Cortexa 7202 MAC to duplicate
(or clone) your network card/adapter. You can nd your adapter’s MAC address by doing
the following:
• If you are running Windows 95,98 or Millennium: Go to the Start, Run, type in
command, and press Enter. At the DOS prompt type winipcfg
• If you are running Windows NT 4.0, 2000 or XP: Go to Start, Run, type in
command, and press Enter. At the DOS prompt type ipcong /all.
The Physical Address with 12 digits is your adapter’s MAC address. Enter those 12 digits
into the MAC Address elds, and click Apply. This “clones” your network adapter’s MAC
address to the Cortexa 7202, and prevents you from having to call your ISP to change the
registered MAC address to the adapter’s MAC address.
MTU is a limit, expressed in bytes, on the size of data sent over a network. It is the maximum
size of a single unit (e.g., an Ethernet frame) of digital communications.
