Configuring Web Redirect with 802.1X Authentication
You can configure a WLAN to redirect a user to a particular web page after 802.1X authentication has
completed successfully. You can configure the web redirect to give the user partial or full access to the
network.
Conditional Web Redirect
If you enable conditional web redirect, the user can be conditionally redirected to a particular web page
after 802.1X authentication has completed successfully. You can specify the redirect page and the
conditions under which the redirect occurs on your RADIUS server. Conditions might include the user’s
password reaching expiration or the user needing to pay his or her bill for continued usage.
If the RADIUS server returns the Cisco AV-pair “url-redirect,” then the user is redirected to the specified
URL upon opening a browser. If the server also returns the Cisco AV-pair “url-redirect-acl,” the specified
access control list (ACL) is installed as a preauthentication ACL for this client. The client is not
considered fully authorized at this point and can only pass traffic allowed by the preauthentication ACL.
After the client completes a particular operation at the specified URL (for example, changing a password
or paying a bill), the client must reauthenticate. When the RADIUS server does not return a
“url-redirect,” the client is considered fully authorized and allowed to pass traffic.
Note
The conditional web redirect feature is available only for WLANs that are configured for 802.1X or
WPA+WPA2 Layer 2 security.
After you configure the RADIUS server, you can then configure the conditional web redirect on the
controller using either the controller GUI or CLI.
