6.1.2.3 PSK / None
Configuring WLAN Security
Open-system authentication can be referred to as no authentication, since no actual authentication takes place. When
selecting PSK/None, a client requests (and is granted) authentication with no credential exchange.
NOTE: Although None implies no authentication, this option is also used when
pre-shared keys are used for encryption (thus the /PSK in the description).
6.1.2.4 Captive Portal
Configuring WLAN Security
A captive portal is guest access policy that provides guests temporary and restrictive access to the wireless network. The
primary means of securing such guest access is the use of a captive portal. For an overview of the captive portal process and

6.1.2.5 MAC Registration
Configuring WLAN Security
The MAC Registration feature provides returning captive portal users quicker access to the captive portal.
When a user accesses the captive portal for the first time, user information is gathered and stored. This information is matched
with the MAC address of the device accessing the captive portal. This information is stored on board the wireless controller.
The next time the user accesses the captive portal service using the same device, he/she is authenticated immediately as the
MAC address of the device is available in the wireless controller's database along with the user's identification information.
The user saves time as identification information is not collected again speeding the logon.
The MAC Registration feature must be enabled for each captive portal WLAN.
To enable MAC Registration:
