7.4.5 MAC Filter

This screen allows you to configure the Device to give exclusive access to specific devices (Allow)
or exclude specific devices from accessing the Device (Deny). 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.

DESCRIPTION
This field is available only when you select WPA2.
Pre-authentication enables fast roaming by allowing the wireless client
(already connecting to an AP) to perform IEEE 802.1x authentication with
another AP before connecting to it. Select Enabled to turn on
preauthentication in WAP2. Otherwise, select Disabled.
This field is available only when you select WPA2.
Specify how often wireless clients have to resend usernames and passwords in
order to stay connected. Enter a time interval between 10 and 2147483647
seconds.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
The Group Key Update Timer is the rate at which the AP (if using WPA(2)-
PSK key management) or RADIUS server (if using WPA(2) key management)
sends a new group key out to all clients. The re-keying process is the WPA(2)
equivalent of automatically changing the WEP key for an AP and all stations in
a WLAN on a periodic basis. Setting of the Group Key Update Timer is also
supported in WPA(2)-PSK mode. The Device default is 1800 seconds (30
minutes).
Enter the IP address of the external authentication server in dotted decimal
notation.
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.
Enter a password (up to 31 alphanumeric 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.
