Configuring Hotspots. A hotspot is essentially a Web page granting user access to the Internet (in this
case within a controller managed WLAN). With the influx of Wi-Fi enabled mobile devices (laptops,
PDAs etc.), hotspots are common and can be found at many airports, hotels and college campuses.
The controller enables hotspot operators to provide user authentication and accounting without a
special client application. The controller uses a traditional Internet browser as a secure authentication
device. Rather than rely on built-in 802.11security features to control association privileges, configure a
WLAN with no WEP (an open network). The controller issues an IP address using a DHCP server,
authenticates the user and grants the user access the Internet.
The hotspot feature supports both internal and external radius servers. It also supports the following
three HTTP redirection options to satisfy various customer configurations:
1 Simple internal pre-built web-pages.
2 External Web-pages
3 Customized internal Web page (using the Advanced feature in hotspot configuration)
When a user visits a public hotspot and wants to browse a Web page, they can boot up their laptop and
associate with the local Wi-Fi network by entering the correct SSID. They then start a browser. The

Specify the maximum number of times the controller retransmits an EAP-
Request frame to the client before it times out the authentication
session. The default is 3 retries, with a maximum of 100 supported.
