Configuration Tasks

Configuration Tasks

After AAA configuration is complete, the device authenticates users and authorizes users to use particular services. In addition, the device also records the network resource usage of the user.

The device supports the combination of local, Remote Authentication Dial In User Service (RADIUS), and Huawei Terminal Access Controller Access Control System (HWTACACS) authentication, authorization, and accounting. For example, the device can provide local authentication, local authorization, and RADIUS accounting.

In practice, as shown in Table 1-22, the following schemes are used separately. Multiple authentication or authorization modes can be used in a scheme. For example, local authentication can be used as a backup of RADIUS authentication and HWTACACS authentication, and local authorization can be used as a backup of HWTACACS authorization.

Overview

Task

Local authentication and authorization

If users need to be authenticated or authorized but no RADIUS server or HWTACACS server is deployed on the network, use local authentication and authorization. Local authentication and authorization feature fast processing and low operation costs. However, the amount of information that can be stored is limited by the device hardware capacity.

Local authentication and authorization are often used for administrators.

Configuring Local Authentication and Authorization

RADIUS authentication, authorization, and accounting

RADIUS protects a network from unauthorized access, which is often used on networks demanding high security and remote user access control.

Configuring RADIUS AAA

HWTACACS authentication, authorization, and accounting

HWTACACS protects a network from unauthorized access and supports command-line authorization. Compared with RADIUS, HWTACACS is more reliable in transmission and encryption, and is more suitable for security control.
