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 .
