LABEL DESCRIPTION
Key Management
Protocol
Choose WPA in this field.
WPA Mixed Mode The Prestige can operate in WPA Mixed Mode , which supports both clients
running WPA and clients running dynamic WEP key exchange with 802.1x in the
same Wi-Fi network.
Select the check box to activate WPA mixed mode. Otherwise, clear the check
box and configure the Group Data Privacy field.
Group Data Privacy Group Data Privacy allows you to choose TKIP (recommended) or WEP for
broadcast and multicast ("group") traffic if the Key Management Protocol is
WPA and WPA Mixed Mode is disabled. WEP is used automatically if you have
enabled WPA Mixed Mode .
All unicast traffic is automatically encrypted by TKIP when WPA or WPA-PSK
Key Management Protocol is selected.
WPA Group Key
Update Timer
The WPA Group Key Update Timer is the rate at which the AP (if using WPA-
PSK key management) or RADIUS server (if using WPA key management)
sends a new group key out to all clients. The re-keying process is the WPA
equivalent of automatically changing the WEP key for an AP and all stations in a
WLAN on a periodic basis. Setting of the WPA Group Key Update Timer is also
supported in WPA-PSK mode. The Prestige default is 1800 seconds (30
minutes).
Authentication
Databases
When you configure Key Management Protocol to WPA , the Authentication
Databases must be RADIUS Only . You can only use the Local User Database
Only with 802.1x Key Management Protocol .
