LANs (PWLANs). In PWLANS, a user scans for available broadband networks, then is
redirected to a web-based authentication mechanism to request service.
DHCP provides address assignment information for users. Authentication, authorization,
and accounting are separate processes, and are up to the Internet service provider (ISP)
to define.
The DHCP local server can configure a client with the following DHCP options:
Default router
DNS server
Domain name
Lease time
Grace period for address lease
NetBIOS name server
NetBIOS node type
Subnet mask
For additional information on managing client bindings, see "Viewing and Deleting DHCP
Client Bindings" on page 453.
In equal-access mode, the router enables access to non-PPP users. Non-PPP equal
access requires the use of the router's DHCP local server and SRC software, which
communicates with a RADIUS server.
The DHCP local server performs the following functions in equal-access mode:
Communicates with SRC software.
Assigns an IP address that enables the subscriber to access services.
The DHCP local server selects a DHCP pool from which to allocate an address using a
number of parameters in a certain predefined sequence. The router compares the
parameters with the local DHCP pools in the order presented in Table 98 on page 459.
When the router finds a match, it selects a pool based on the match and does not examine
other parameters.
