NID naming and security
This chapter explains how to use NID names to:
• identify and keep track of Nokia A032 users
• control access to a Nokia A032 network.
NID names provide level 1 security features (see
Authentication and encryption on page 128).
Each station on a network, whether it be
wireless or wired, has a unique identifying
number called the MAC address.
Both Ethernet and IEEE802.11 stations use a
48-bit number, usually expressed as six bytes
in hexadecimal notation. An example of a MAC
address is:
00e003123456
The address is associated with the network
adapter card and not the computer, so that if
you move an Ethernet card or wireless LAN
card to a new computer, the number will
transfer to the new location. No two adapters in
the world can legally have the same MAC
address.
