Accounting, Authentication, and Authorization (AAA) services secure networks against unauthorized access. In addition to local authentication, SmartFabric OS10 supports Remote Authentication Dial-In Service (RADIUS) and Terminal Access Controller Access Control System+ (TACACS+) client/server authentication systems. For RADIUS and TACACS+, an SmartFabric 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 accounting, authentication (user credentials verification), and authorization (user privilege-level) services. You can configure the security protocol used for different login methods and users. The server uses a list of authentication methods to define the types of authentication and the sequence in which they apply.
