Local portal service

As shown in Figure 51, a local portal system consists of an authentication client, access device, and AAA server. The access device acts as both the portal Web server and the portal authentication server to provide the local portal Web service for the authentication client. The authentication client can only be a Web browser, and it cannot be a user host that runs a portal client. Therefore, extended portal functions are not supported and no security policy server is required.

To provide the local portal web service, you must customize a set of authentication pages that the device will push to users. You can customize multiple sets of authentication pages, compress each set of the pages to a .zip file, and upload the compressed files to the storage medium of the device. On the device, you must specify one of the files as the default authentication page file by using the default-logon-page command.
