The device supports external and built-in Portal servers. An external Portal server has independent hardware. A built-in Portal server is an embedded entity on an access device, that is, the access device functions as the Portal server. After receiving a Portal authentication request from a client, the Portal server initiates a Portal authentication request carrying the user name and password to the access device through the Portal protocol.
After configuring the Portal server, you must bind the Portal server template to a Portal access profile. When users who use the Portal access profile attempt to access charged network resources, they are forcibly redirected to the authentication page of the Portal server for Portal authentication.
This section describes how to configure the Portal server and Portal access profile when using an external Portal server.
