DESCRIPTION

 

 

 

 

 

 

Idle Timeout

The ZyAIR automatically disconnects a wireless station from the wired network after

 

 

 

a period of inactivity. The wireless station 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

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

 

 

Protocol

 

 

 

 

 

 

 

Dynamic WEP Key

This field is activated only when you select Authentication Required in the

 

 

Exchange

Wireless Port Control field and set the Key Management Protocol to 802.1x.

 

 

 

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-PSKin the Key Management

 

 

 

Protocol field.

 

 

Data Privacy for

This field allows you to choose TKIP (recommended) or WEP for broadcast and

 

 

Broadcast/Multicast

multicast (“group”) traffic if the Key Management Protocol is WPA or WPA-PSK.

 

 

packets

All unicast traffic is automatically encrypted by TKIP when WPA or WPA-PSK Key

 

 

 

 

 

 

Management Protocol is selected.

 

 

 

 

 

 

WPA

The WPA Broadcast/Multicast Key Update Timer is the rate at which the AP (if

 

 

Broadcast/Multicast

using WPA-PSKkey management) or RADIUS server (if using WPA key

 

 

Key Update Timer

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).
