Chapter 6 - Authorization
Authorization entails determining if a particular user has permission to use a service.
Authorization
The SMS2000 is capable of performing authorization by using an external server (OCS
or RADIUS) or by using onboard groups and rules. For details about using the OCS for
Authorization, see the OCS User’s Guide. For more information on RADIUS, see
Chapter 13, “Using SMS2000 with a RADIUS Server.” Scenarios for performing these
functions in various configurations are described below.
Authorization
Table 6-1 shows how authorization is performed with no external server, with RADIUS,
and with the OCS.

No user authentication is possible. Groups and rules can be used to
authorize subscribers based on their MAC address, VLAN ID, SNMP
information, IP address, or any combination of these. For more information
on using groups and rules, see Chapter 10, “Service Creation using Groups
and Rules.”
