Configuring Aaa Authentication Methods For An Isp Domain - 3Com 4210G Series Configuration Manual

A self-service RADIUS server, for example, 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:
No authentication: All users are trusted and no authentication is performed. Generally, this
method is not recommended.
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.
Remote authentication: The access device cooperates with a RADIUS or HWTACACS 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 in case 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:
For RADIUS or HWTACACS authentication, configure the RADIUS or HWTACACS scheme to be
referenced first. The local and none authentication methods do not require any scheme.
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.
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:
