AAA Scheme

You can add, modify, and delete an authentication scheme, authorization scheme, or accounting scheme. The S2300EI,S2352EI, or S2300SI switches do not support this function.

Context

Authentication, authorization, and accounting are three independent service processes.

In the authentication process, a device authenticates the user name, password, or user information of an access request or a service request. The device, however, neither delivers authorization information to the user nor triggers the accounting process. In AAA, a device can adopt only authentication.
In the authorization process, a device sends authorization requests to the authorization server. After users pass authorization, the device sends authorization information to users. If the authorization scheme is none, users do not need to be authorized. In this case, users passing authentication have the default authority granted by the system.
In the accounting process, a device sends accounting-start packets, accounting-update packets, or accounting-stop packets to the accounting server. In AAA, an accounting scheme is optional. If you do not configure an accounting scheme.
