Once you enable user authentication, you need to specify an external RADIUS server or create
local user accounts on the Prestige for authentication.
Dynamic WEP
Key Exchange This field is activated only when you select Authentication Required in the Wire-
less Port Control field. Also set the Authentication Databases field to RADIUS
Only.
Select Disable to allow wireless stations to communicate with the access points with-
out using Dynamic WEP Key Exchange.
Select 64-bit WEP or 128-bit WEP to enable data encryption.
Up to 32 stations can access the Prestige when you configure Dynamic WEP Key
Exchange.
PSK Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including
spaces and symbols) when you select WPA-PSK in the Key Management Protocol
field.
WPA Mixed
Mode Select Enable to activate WPA mixed mode. Otherwise, select Disable and
configure Group Data Privacy field.
Data Privacy for
Broadcast/
Multicast
packets 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 Broadcast/
Multicast 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 The RADIUS is an external server.
Select RADIUS Only to have the Prestige just check the user database on the
specified RADIUS server for a wireless station's username and password.
