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.

Data Privacy for Broadcast/Multicast packets field.
Data Privacy
for Broadcast/
Multicast
packets This field 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 Broadcast/Multicast 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 Broadcast/Multicast Key Update Timer is also
supported in WPA-PSK mode. The ZyAIR default is 1800 seconds (30 minutes).
