How to configure built-in Portal authentication on S series switches

In built-in Portal authentication, the access device uses the built-in Portal server to implement Portal authentication. Only fixed switches support built-in Portal authentication.
For fixed 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. By default, the unified mode is used. Accordingly, built-in Portal authentication 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.
