6.8 MAC Filter Screen
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 address of each device to configure MAC filtering
on the NWA1121-NI.
The MAC filter function allows you to configure the NWA1121-NI to grant access to the NWA1121-
NI from other wireless devices (Allow Association) or exclude devices from accessing the NWA1121-
NI (Deny Association).
Figure 38 MAC Filtering
In the figure above, wireless client U is able to connect to the Internet because its MAC address is
in the allowed association list specified in the NWA1121-NI. The MAC address of client A is either
denied association or is not in the list of allowed wireless clients specified in the NWA1121-NI.
