Table 7-7 Wireless LAN: 802.1x/WPA for WPA-PSK Protocol 
LABEL DESCRIPTION 
Key Management 
Protocol 
Choose WPA-PSK in this field. 
Pre-Shared Key 
The encryption mechanisms used for WPA and WPA-PSK are the same. The only 
difference between the two is that WPA-PSK uses a simple common password, 
instead of user-specific credentials. 
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including spaces 
and symbols). 
WPA Mixed Mode 
The ZyAIR 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 Enable to activate WPA mixed mode. Otherwise, select Disable.  
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 ZyAIR default is 1800 seconds (30 minutes).  
Authentication 
Databases 
This field is only visible when WPA Mixed Mode is enabled. 
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
7.13  Introduction to Local User Database 
By storing user profiles locally on the ZyAIR, your ZyAIR is able to authenticate wireless users without 
interacting with a network RADIUS server. However, there is a limit on the number of users you may 
authenticate in this way. 
7.14  Configuring Local User Database  
To change your ZyAIR’s local user database, click ADVANCEDWIRELESS and then the Local User 
Database
 tab. The screen appears as shown (some of the screen’s blank rows are not shown).
