Taken together, a MAC Address/Mask pair specifies an address or a
range of MAC addresses that the AP will look for when examining
packets. The AP uses Boolean logic to perform an "AND" operation
between the MAC Address and the Mask at the bit level. However, for
most users, you do not need to think in terms of bits. It should be
sufficient to create a filter using only the hexadecimal digits 0 and F in the
Mask (where 0 is any value and F is the value specified in the MAC
address).
• A Mask of 00:00:00:00:00:00 corresponds to all MAC addresses,
and
• A Mask of FF:FF:FF:FF:FF:FF applies only to the specified MAC
Address.
For example, if the MAC Address is 00:20:A6:12:54:C3 and the Mask is
FF:FF:FF:00:00:00, the AP will examine the source and destination
addresses of each packet looking for any MAC address starting with
00:20:A6. If the Mask is FF:FF:FF:FF:FF:FF, the AP will only look for
the specific MAC address (in this case, 00:20:A6:12:54:C3).
When creating a filter, you can configure the Wired parameters only, the
Wireless parameters only, or both sets of parameters. Which parameters
to configure depends upon the traffic that you want block:
• To prevent all traffic from a specific wired MAC address from being
forwarded to the wireless network, configure only the Wired MAC
Address and Wired Mask (leave the Wireless MAC Address and
