Table 32-2 Menu 23.4 System Security : IEEE802.1x

FIELD DESCRIPTION

Idle Timeout
(in second)

The ZyAIR automatically disconnects a client from the wired network after a period of
inactivity. The client needs to enter the username and password again before access to
the wired network is allowed.

This field is activated only when you select Authentication Required in the Wireless
Port Control
field. The default time interval is 3600 seconds (or 1 hour).

Key
Management
Protocol

Press [SPACE BAR] to select 802.1x, WPA or WPA-PSK and press [ENTER].

Dynamic WEP
Key Exchange

This field is activated only when you select Authentication Required in the Wireless
Port Control
field. Also set the Authentication Databases field to RADIUS Only.
Local user database may not be used.

Select Disable to allow wireless stations to communicate with the access points without
using Dynamic WEP Key Exchange.

Select 64-bit WEP or 128-bit WEP to enable data encryption.

Up to 32 stations can access the ZyAIR 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/Mult
icast 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/Mult
icast 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).
