The WPA configuration parameters are described below:
Authentication Type Setup – When using WPA, set the access
point to communicate as an open system to disable WEP keys.
Note: Although WEP keys are not needed for WPA, you must enable
WEP encryption through the web or CLI in order to enable all
types of encryption in the access point. For example, set Wired
Equivalent Privacy (WEP) Setup to "Enable" on the Security page.
WPA Configuration Mode – The access point can be configured
to allow only WPA-enabled clients to access the network, or also
allow clients only capable of supporting WEP.
WPA Key Management – WPA can be configured to work in an
enterprise environment using IEEE 802.1X and a RADIUS server
for user authentication. For smaller networks, WPA can be
enabled using a common pre-shared key for client authentication
with the access point.
•
WPA authentication over 802.1X: The WPA enterprise mode
that uses IEEE 802.1X to authenticate users and to
dynamically distribute encryption keys to clients.
•
WPA Pre-shared Key: The WPA mode for small networks that
uses a common password string that is manually distributed.
If this mode is selected, be sure to also specify the key string.
Multicast Cipher Mode – Selects an encryption method for the
global key used for multicast and broadcast traffic, which is
supported by all wireless clients.
•
WEP: WEP is the first generation security protocol used to
encrypt data crossing the wireless medium using a fairly short
key. Communicating devices must use the same WEP key to
encrypt and decrypt radio signals. WEP has many security
flaws, and is not recommended for transmitting
highly-sensitive data.
