Figure 4-26 Static MAC Filter Configuration
Each static MAC entry contains the following fields:
• Wired MAC Address
• Wired Mask
• Wireless MAC Address
• Wireless Mask
• Comment: This field is optional.
Each MAC Address or Mask is comprised of 12 hexadecimal digits (0-9, A-F) that correspond to a 48-bit identifier. (Each
hexadecimal digit represents 4 bits (0 or 1).)
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 Wireless Mask set to all zeros).
• To prevent all traffic from a specific wireless MAC address from being forwarded to the wired network, configure only
the Wireless MAC address and Wireless Mask (leave the Wired MAC Address and Wired Mask set to all zeros).
• To block traffic between a specific wired MAC address and a specific wireless MAC address, configure all four
parameters.
