1) Determine the access mode or service type to be configured. With AAA, you can configure an
authorization scheme specifically for each access mode and service type, limiting the authorization
protocols that can be used for access.
2) Determine whether to configure an authorization method for all access modes or service types.
Follow these steps to configure AAA authorization methods for an ISP domain:

radius-scheme
radius-scheme-name
[

Optional
The default authorization

z
The authorization method specified with the
authorization default
command is for all types of
users and has a priority lower than that for a specific access mode.
z
RADIUS authorization is special in that it takes effect only when the RADIUS authorization scheme
is the same as the RADIUS authentication scheme. In addition, if a RADIUS authorization fails, the
error message returned to the NAS says that the server is not responding.
z
With the
radius-scheme radius-scheme-name local
keyword and argument combination
configured, local authorization or no authorization is the backup method and is used only when the
remote server is not available.
z
If the primary authorization method is
local
or
none
, the system performs local authorization or
does not perform any authorization; it will never use the RADIUS authorization scheme.
z
The authorization information of the RADIUS server is sent to the RADIUS client along with the
authentication response message; therefore, you cannot specify a separate RADIUS authorization
server. If you use RADIUS for authorization and authentication, you must use the same scheme
setting for authorization and authentication; otherwise, the system will prompt you with an error
message.
Configuring AAA Accounting Methods for an ISP Domain
In AAA, accounting is a separate process at the same level as authentication and authorization. Its
responsibility is to send accounting start/update/end requests to the specified accounting server.
Accounting is not required, and therefore accounting method configuration is optional.
