Static MAC Filter Examples
Consider a network that contains a wired server and three wireless clients. The MAC address for each unit is as follows:
• Wired Server: 00:40:F4:1C:DB:6A
• Wireless Client 1: 00:02:2D:51:94:E4
• Wireless Client 2: 00:02:2D:51:32:12
• Wireless Client 3: 00:20:A6:12:4E:38
Prevent Two Specific Devices from Communicating
Configure the following settings to prevent the Wired Server and Wireless Client 1 from communicating:
• Wired MAC Address: 00:40:F4:1C:DB:6A
• Wired Mask: FF:FF:FF:FF:FF:FF
• Wireless MAC Address: 00:02:2D:51:94:E4
• Wireless Mask: FF:FF:FF:FF:FF:FF
Result: Traffic between the Wired Server and Wireless Client 1 is blocked. Wireless Clients 2 and 3 can still communicate
with the Wired Server.
Prevent Multiple Wireless Devices from Communicating with a Single Wired Device
Configure the following settings to prevent Wireless Clients 1 and 2 from communicating with the Wired Server:
• Wired MAC Address: 00:40:F4:1C:DB:6A
• Wired Mask: FF:FF:FF:FF:FF:FF
• Wireless MAC Address: 00:02:2D:51:94:E4
• Wireless Mask: FF:FF:FF:00:00:00
Result: When a logical "AND" is performed on the Wireless MAC Address and Wireless Mask, the result corresponds to
any MAC address beginning with the 00:20:2D prefix. Since Wireless Client 1 and Wireless Client 2 share the same
prefix (00:02:2D), traffic between the Wired Server and Wireless Clients 1 and 2 is blocked. Wireless Client 3 can still
communicate with the Wired Server since it has a different prefix (00:20:A6).
