The following table describes the labels in this screen.
7.8 MAC Filter
The MAC filter screen allows you to give exclusive access to up to 32 devices (Allow
Association) or exclude up to 32 devices from accessing the device (Deny Association). Every
Ethernet device has a unique MAC (Media Access Control) address. The MAC address is
assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. You need to know the MAC addresses of the devices to configure this
screen.
The MAC filter works when the device functions as an AP. It allows or denies wireless client
access. The MAC filter does not apply to bridge or repeater functions.

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 bits WEP, 128 bits WEP or 152 bits WEP to enable data encryption.
Up to 32 stations can access the device when you configure dynamic WEP key
exchange.
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.
Apply Click Apply to save your changes back to the device.
Reset Click Reset to begin configuring this screen afresh.
