Configuring Captive Portal Policies
A captive portal is guest access policy for providing guests temporary and restrictive access to the access
point managed wireless network.
A captive portal policy’s configuration provides secure authenticated access using a standard Web
browser. Captive portals provide authenticated access by capturing and re-directing a wireless user's
Web browser session to a captive portal login page where the user must enter valid credentials to access
to the wireless network. Once logged into the captive portal, additional
Terms and Conditions , Welcome
and Fail pages provide the administrator with a number of options on screen flow and appearance.
Captive portal authentication is used primarily for guest or visitor access to the network, but is
increasingly being used to provide authenticated access to private network resources when 802.1X EAP
is not a viable option. Captive portal authentication does not provide end-user data encryption, but it
can be used with static WEP, WPA-PSK or WPA2-PSK encryption.
Each supported access point model can support up to 32 captive portal policies, with the exception of
Altitude 4511 and Altitude 4521 models, which can only support 16 captive portal policies.
