Table 20 Wireless Security: WPA(2)
LABEL DESCRIPTION
Encryption
Method
Select WPA, WPA2 or WPA & WPA2 to configure user authentication and
improved data encryption.
Note: WPA, WPA2 and IEEE 802.1x wireless security are not
available when you use Wireless Client, Bridge or
AP+Repeater mode.
Note: You can only use WEP keys to encrypt traffic between APs.
Authentication
Server IP Address
Enter the IP address of the external authentication server in dotted decimal
notation.
Port Number Enter the port number of the external authentication server. The default port
number is 1812.
You need not change this value unless your network administrator instructs you to
do so with additional information.
Shared Secret Enter a password (up to 63 printable characters) as the key to be shared between
the external authentication server and the device.
The key must be the same on the external authentication server and your device.
The key is not sent over the network.
Reauthentication
Time
Specify how often wireless stations have to resend user names and passwords in
order to stay connected. Enter a time interval between 100 and 3600 seconds.
If wireless station authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
Global-Key
Update
This is how often the AP 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.
Specify an interval either in seconds or thousands of packets that the device
sends.
