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 hotspot
access controller forces this un-authenticated user to a Welcome page from the hotspot Operator that allows
the user to login with a username and password. This form of IP-Redirection requires no special software on
the client.
To configure a hotspot, create a WLAN ESSID and select Hotspot as the authentication scheme from the
WLAN Authentication menu. This is simply another way to authenticate a WLAN user, as it would be
impractical to authenticate visitors using 802.1x authentications. Having enabled a hotspot, you will need to
configure it. There are 2 parts to the hotspot configuration process:
• Setting up the Hotspot Web pages
• Setting up the Radius server.
Switch Hotspot Redirection
The switch uses destination network address translation to redirect user traffic from a default home page to
the login page. Specifically, when the switch receives an HTTP Web page request from the user (when the
client first launches its browser after connecting to the WLAN), a protocol stack on the switch intercepts the
request and sends back an HTTP response after modifying the network and port address in the packet
(thereby acting like a proxy between the User and the Web site they are trying to access).
To configure hotspot support:
1. Select Network > Wireless LANs from the main menu tree.
2. Select an existing WLAN from those displayed within the Configuration tab and click the Edit button.
A WLAN screen displays with the WLAN’s existing configuration. Refer to the Authentication and
Encryption columns to assess the WLAN’s existing security configuration.
3. Select the Hotspot button from within the Authentication field. The Radius Config... button on the
bottom of the screen becomes enabled. Ensure a primary and optional secondary Radius Server have
been configured to authenticate users requesting access to the hotspot supported WLAN. For more
information, see Configuring External Radius Server Support on page 4-49.
4. Click the Config button to the right of the Hotspot checkbox.
A Hotspot screen displays, allowing the user to define one of three available hotspot types.
5. Use the drop-down menu at the top of the screen to define whether this WLAN’s Web pages are:
• Internal - three HTML pages with basic functionality are made available on the switch's onboard
HTTP server. The HTML pages are pre-created to collect login credentials through Login.htm, send
them to a Radius server and display a Welcome.htm or a Faliure.htm depending on the result of the
authentication attempt. For more information, see Configuring an Internal Hotspot on page 4-37.
• External - a customer may wish to host their own external Web server using advanced Web content
(using XML, Flash). Use the External option to point the switch to an external hotspot. For more
information, see Configuring an External Hotspot on page 4-40.
• Advanced - a customer may wish to use advanced Web content (XML, Flash) but might not have (or
would not want to use) an external Web server, choosing instead to host the Web pages on the
switch's HTTP Web server. Selecting the Advanced option allows for the importing the Web pages
from an external source (like an FTP server) and hosting them on the switch. For more information,
