AAA

Authentication, authorization, and accounting (AAA) services secure networks against unauthorized access. In addition to local authentication, OS10 supports remote authentication dial-in user service (RADIUS) and terminal access controller access control system (TACACS+) client/server authentication systems. For RADIUS and TACACS+, an OS10 switch acts as a client and sends authentication requests to a server that contains all user authentication and network service access information.

A RADIUS or TACACS+ server provides: authentication of user credentials, authorization using role-based permissions, and accounting services. You can configure the security protocol used for different login methods and users. RADIUS provides limited authorization and accounting services compared to TACACS+. If you use a RADIUS or TACACS+ security server, configure the required security parameters on the server by following the procedures in the server documentation.

AAA configuration

On the switch, AAA configuration consists of setting up access control and accounting services:
  1. Configure the authentication methods used to allow access to the switch.
  2. Configure the level of command authorization for authenticated users.
  3. Configure security settings for user sessions.
  4. Enable AAA accounting.
