DESCRIPTION
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).
Press [SPACE BAR] to select 802.1x, WPA, WPA2, WPA-PSK or WPA2-PSK
and press [ENTER].
This field is activated only when you select Authentication Required in the
Wireless Port Control field. Also set the Key Management Protocol field to
802.1x.
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 Prestige when you configure Dynamic WEP
Key Exchange.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including
spaces and symbols) when you select WPA-PSK or WPA2-PSK in the Key
Management Protocol field.
Select Enable to have both WPA2 and WPA wireless clients be able to
communicate with the Prestige even when the Prestige is using WPA2-PSK or
WPA2. Otherwise, select Disable.
The WPA Broadcast/Multicast Key Update Timer is the rate at which the AP (if
using WPA-PSK/WPA2-PSK key management) or RADIUS server (if using
WPA/WPA2 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/WPA2-
PSK mode. The default is 1800 seconds (30 minutes).
The authentication database contains wireless station login information. The
RADIUS is an external server.
When you configure Key Management Protocol to WPA, WPA2 or 802.1x, the
Authentication Databases is RADIUS Only.
Before you enable wireless LAN and use WPA, WPA2 or IEEE 802.1x
authentication, make sure you have set up an external server correctly first. The
Prestige checks the user database on the specified RADIUS server for a wireless
station's username and password. When the user name is not found or password
does not match in the RADIUS server, the authentication will fail.
