About Web-Based Authentication

Customization of the Authentication Proxy Web Pages

During the web-based authentication process, the internal HTTP server of the switch hosts four HTML
pages for delivery to an authenticating client. The four pages allow the server to notify you of the
following four states of the authentication process:
•
•
•
•
When your customized web-based authentication page is replaced with a new page (file) of the same
Note
name in the switch system directory (i.e. flash), the new page will not be seen; you will see the older
page. Beginning with Release 15.0(2)SG, the new page will not display until you enter the ip admission
proxy http refresh-all command.
In Cisco IOS Release 12.2(50)SG, you can substitute your custom HTML pages for the four default
internal HTML pages, or you can specify a URL to which you are redirected upon successful
authentication, effectively replacing the internal Success page.

Port Security
You can configure web-based authentication and port security on the same port. (You configure port
security on the port with the switchport port-security interface configuration command.) When you
enable port security and web-based authentication on a port, web-based authentication authenticates the
port, and port security manages network access for all MAC addresses, including that of the client. You
can then limit the number or group of clients that can access the network using the port.
