5.8.2 Static MAC Address Filters
The Static MAC Address filter optimizes the performance of a wireless (and wired) network. With this feature configured, the
AP device can block traffic between wired devices and wireless devices based on the MAC address.
For example, you can set up a Static MAC filter to prevent wireless clients from communicating with a specific server on the
ethernet network. You can also use this filter to block unnecessary multicast packets from being forwarded to the wireless
network.
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 device will look for
when examining packets. The AP device uses Boolean logic to perform an “AND” operation between the MAC Address and
the Mask at the bit level. 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 device 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 device will only look for the specific MAC address (in this case, 00:20:A6:12:54:C3).
You can configure the Static MAC Address Filter parameters depending on the following scenarios:
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 prevent traffic between a specific wired MAC address and a specific wireless MAC address, configure all four
parameters. Configure the wired and wireless MAC address and set the wired and wireless mask to all Fs.
To prevent all traffic from a specific wired Group 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).
