Logging In to a Captive Portal
The wireless controller lets you create a captive portal, which allows you to control which
web page is viewed when users first log onto a WLAN. Captive portals are used to control
Wi-Fi access at locations where users are "captive," such as hotels, apartments, business
centers, coffee houses, and restaurants.
A captive portal turns a user's web browser into an authentication device by intercepting all
packets, regardless of address or port, when the user opens a browser and tries to access
the Internet. At that time, the browser is redirected to a web page that might require
authentication, payment, or user agreement to a use policy.
Figure 2-7 shows an example of a captive portal configuration with a wireless controller,
access points, PoE switch, and RADIUS authentication server.
In this configuration, you:
•
Create a group configured for captive portal users.
•
Add the captive portal users to the group and assign a password and idle timeout value to
it.
•
Select an interface for the captive portal.
•
Test your settings and make any necessary adjustments.
