3-2 CHAPTER 3: WINDOWS NT DRIVER INSTALLATION
addresses, Client 0 through Client 3, are assigned
to the adapter. Each client has a MAC address, with
Client 0 being assigned the true MAC address of the
3C971-F adapter. Clients 1 through 3 have a virtual
MAC address, assigned by the driver, that is an
increment of the true MAC address. Duplicate MAC
addresses cannot occur on the network. The true
MAC assignments at the factory are spaced in
increments of 16 addresses. You are not required to
use the three additional clients. Client 0, however,
represents the true MAC addresses of the 3C971-F
adapter and cannot be disabled.
Each client can be set to contact (at bootup time) a
LAN emulation configuration server (LECS) using
the ATM Forum’s “well-known” LECS address. The
LECS contains all the necessary configuration
information for each client to connect to the
appropriate LAN emulation server. If an LECS is not
in use or not available on the network, the user can
set the client to contact an LES directly by entering
the LES’s 20-byte ATM address.
