A self-service RADIUS server, for example Intelligent Management Center (iMC), is required for the
self-service server localization function to work. With the self-service function, a user can manage and
control his or her accounting information or card number. A server with self-service software is a
self-service server.
Configuring AAA Authentication Methods for an ISP Domain
In AAA, authentication, authorization, and accounting are separate processes. Authentication refers to
the interactive authentication process of username/password/user information during access or service
request. The authentication process neither sends authorization information to a supplicant nor triggers
any accounting.
AAA supports the following authentication methods:
z No authentication: All users are trusted and no authentication is performed. Generally, this method
is not recommended.
z Local authentication: Authentication is performed by the NAS, which is configured with the user
information, including the usernames, passwords, and attributes. Local authentication features
high speed and low cost, but the amount of information that can be stored is limited by the
hardware.
z Remote authentication: The access device cooperates with a RADIUS server to authenticate users.
As for RADIUS, the device can use the standard RADIUS protocol or extended RADIUS protocol in
collaboration with systems like iMC to implement user authentication. Remote authentication
features centralized information management, high capacity, high reliability, and support for
centralized authentication for multiple devices. You can configure local authentication as the
backup method to be used when the remote server is not available.
You can configure AAA authentication to work alone without authorization and accounting. By default,
an ISP domain uses the local authentication method.
Before configuring authentication methods, complete these three tasks:
z For RADIUS authentication, configure the RADIUS scheme to be referenced first. The local and
none authentication methods do not require any scheme.
z Determine the access mode or service type to be configured. With AAA, you can configure an
authentication method specifically for each access mode and service type, limiting the
authentication protocols that can be used for access.
z Determine whether to configure an authentication method for all access modes or service types.
Follow these steps to configure AAA authentication methods for an ISP domain:
