How to configure remote authentication for 802.1x authentication users on S series switches

802.1x authentication user information (including the user name, password, and other attributes) for remote authentication and authorization is configured on a remote AAA server. Remote authentication and authorization for 802.1x authentication users feature high network security.
For S series and E series switches (except the S1700) running V200R003C10 and earlier versions, NAC can be configured only in common mode. For switches running V200R005C00 and later versions, NAC can be configured in common or unified mode. Accordingly, remote authentication for 802.1x authentication users can be configured in common or unified mode. For switches running V200R009C00, the configuration model of NAC unified mode changes. Query the appropriate product manual based on the switch model and version. The following links are for reference only.
