802.1x remote authentication on S series switch

In 802.1x remote authentication and authorization, user information (including the user name, password and attributes) is configured on the remote AAA server. 802.1x remote authentication and authorization feature high network security.
S series switches (except S1700 switches) running V200R003C10 or an earlier version supports only traditional NAC configuration. Switches running V200R005C00 or a later version support both traditional and unified NAC configuration. By default, unified NAC configuration is used. 802.1x remote authentication also supports traditional and unified modes. 802.1x remote authentication configuration is the same on all switch models:
