About portal authentication
Portal authentication controls user access to networks. Portal authenticates a user by the username and password the user enters on a portal authentication page. Typically, portal authentication is deployed on the access layer and vital data entries.
In a portal-enabled network, users can actively initiate portal authentication by visiting the authentication website provided by the portal Web server. Or, they are redirected to the portal authentication page for authentication when they visit other websites.
The device supports Portal 1.0, Portal 2.0, and Portal 3.0.
