The following table describes the labels in this screen.
Table 21 Wireless Security: 802.1x
LABEL DESCRIPTION
Encryption Method Select 802.1X to configure authentication of wireless stations and encryption key
management.
Note: WPA, WPA2 and IEEE 802.1x wireless security are not
available when you use Bridge or AP+Repeater mode. You
can only use WEP keys to encrypt traffic between APs.
Data Encryption Select None 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 device when you configure dynamic WEP key
exchange.
Passphrase Enter a “passphrase” (password phrase) of up to 16 case-sensitive printable
characters and click Generate .
Generate After you enter the passphrase, click Generate to have the device generates four
different WEP keys automatically.
Key 1 to
Key 4 If you want to manually set the WEP keys, enter the WEP key in the field provided.
Select a WEP key to use for data encryption.
The WEP keys are used to encrypt data. Both the device and the wireless stations
must use the same WEP key for data transmission.
If you chose
64-bit WEP , then enter any 5 ASCII characters or 10 hexadecimal
characters ("0-9", "A-F").
If you chose
128-bit WEP , then enter 13 ASCII characters or 26 hexadecimal
characters ("0-9", "A-F").
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 64 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.
Apply Click Apply to save your changes back to the device.
Reset Click Reset to begin configuring this screen afresh.
