RADIUS authentication is a remote authentication mode. An access device as a RADIUS client collects user information (such as user name and password) and sends the user information to a remote RADIUS server (AAA server). The RADIUS server authenticates users according to the information, and performs authorization and accounting for the users after the users are authenticated.The RADIUS server uniformly authenticates and manages (such as charging) users to ensure network security.
On an S series switch, except S1700, RADIUS authentication can be performed on both administrators and other users. The implementations on different models are the same.For the configuration methods, see Example for Configuring Authentication for Telnet Login Users (RADIUS Authentication) and Example for Configuring 802.1x Authentication to Control Internal User Access in theS1720&S2700&S3700&S5700&S6700&S7700&S9700 Typical Configuration Examples
