Idle Timeout

The ZyAIR automatically disconnects a client from the wired network after a period of

 

 

(in second)

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).

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.

 

 

 

This feature is not available on the ZyAIR B-2000.

Privacy

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

The WPA Group Key Update Timer is the rate at which the AP (if using WPA-PSK

 

 

Key Update

key management) or RADIUS server (if using WPA key management) sends a new

 

 

Timer

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).
