Web authentication process

The Web authentication process is as follows:

1. An unauthenticated user sends an HTTP request. When the access device receives the HTTP request on a Layer 2 Ethernet interface enabled with Web authentication, it redirects the request to the Web authentication page. The user enters the username and password on the Web authentication page.

   If the user requests the Web authentication page or free Web resources, the access device permits the request. No Web authentication is performed.

2. The access device and the AAA server exchange RADIUS packets to authenticate the user.

3. If the user passes RADIUS authentication, the local portal Web server pushes a login success page to the authentication client.

   If the user fails RADIUS authentication, the local portal Web server pushes a login failure page to the authentication client.
