• WPA2: WPA2 is an enhanced version of WPA, and defines the 802.11i protocol.
Figure 12-56: Configuring WPA2 Security
a. Authentication Method: select the authentication method ('Pre-Shared Key'
and '802.1x').
b. Pre-Shared Key: this field appears only if you selected this authentication
method. Enter your encryption key in either an ASCII or a Hex value (by
selecting the value type in the drop-down list provided).
c. Pre Authentication: This field appears only when selecting the 802.1x
authentication method. Select this option to enable the device to accept
RADIUS authentication requests from computers connected to other access
points. This enables roaming from one wireless network to another.
d. PMK Cache Period: This field appears only when selecting the 802.1x
authentication method. This field defines the number of minutes before
deletion (and renewal) of the Pairwise Master Key used for authentication.
e. Encryption Algorithm: encryption algorithm for WPA2 is the Advanced
Encryption Standard (AES).
f. Group Key Update Interval: Defines the time interval in seconds for
updating a group key.
• WPA and WPA2: WPA and WPA2 is a mixed data encryption method. For a
description of these fields, see WPA and WPA2 above.
• Non-802.1x WEP: data encryption method utilizing a statically defined key for
wireless clients that do not use 802.1x for authentication, but use WEP for
encryption. You may define up to four keys, but use only one at a time.
