is not applicable for all the default 19 entries.

4.8.2 Static MAC Address Filter
4.8.2.1 Overview
The Static MAC Address filter optimizes the performance of a wireless and wired network. When this feature is configured,
the device can block traffic between wired and wireless network based on MAC address.
The filter limits the data traffic between two specific devices (or between groups of devices based on MAC addresses and
masks) through the unit’s wireless interface. For example, a server on the network, which should not allow wireless clients to
communicate, can be set up with a static MAC filter to block traffic between these devices. The Static MAC Filter Table
performs bi-directional filtering.
Each MAC address or mask consists of 12 hexadecimal digits (0-9 and 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 device looks for when
examining packets. The device performs bitwise “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 device examines 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 device looks only for the specific MAC address (in this case, 00:20:A6:12:54:C3).
When creating a filter, the user can configure the Wired parameters only, the Wireless parameters only, or both sets of
parameters.
• 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 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 and Wireless mask (leave the Wired MAC address and Wired mask set to all zeros).
