Method used to configure RADIUS authentication on the AR

RADIUS authentication is a remote authentication mode. An access device used as a RADIUS client collects user information (such as the user name and password) and sends the user information to a remote RADIUS server (AAA server). The RADIUS server authenticates users based on the information, and performs authorization and accounting for the users after the users are authenticated. The RADIUS server uniformly authenticates and manages (such as accounting) users to ensure network security.
