To prevent all traffic from a specific wireless Group 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 Group MAC address and a specific wireless Group MAC address, configure
all four parameters. Configure the wired and wireless MAC address and set the wired and wireless mask to all Fs.
all four parameters. Configure the wired and wireless MAC address and set the wired and wireless mask to all Fs.
Static MAC Filter Examples
Consider a network that contains a wired PC and three wireless PCs. The MAC addresses for each PCs are as follows:
•
MAC Address of the wired PC: 00:40:F4:1C:DB:6A
•
MAC Address of the wireless PC1: 00:02:2D:51:94:E4
•
MAC Address of the wireless PC2: 00:02:2D:51:32:12
•
MAC Address of the wireless PC3: 00:20:A6:12:4E:38
5.10.2.0.1 Prevent two specific PCs from communicating
Configure the following settings to prevent the wired PC and wireless PC1 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 PC and wireless PC1 is blocked. wireless PC2 and PC3 can still communicate with the wired
PC.
PC.
5.10.2.0.2 Prevent multiple Wireless PCs from communicating with a single wired PC
Configure the following settings to prevent wireless PC1 and PC2 from communicating with the wired PC:
•
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 PC1 and wireless PC2 share the same prefix (00:02:2D),
traffic between the wired Server and wireless PC1 and PC2 is blocked. Wireless PC3 can still communicate with the wired PC
since it has a different prefix (00:20:A6).

since it has a different prefix (00:20:A6).
5.10.2.0.3 Prevent all wireless PCs from communicating with a single wired PC
Configure the following settings to prevent wired PC from communicating with all three wireless PCs:
•
Wired MAC Address: 00:40:F4:1C:DB:6A
•
Wired Mask: FF:FF:FF:FF:FF:FF
•
Wireless MAC Address: 00:00:00:00:00:00
•
Wireless Mask: 00:00:00:00:00:00
Result: The device blocks all traffic between the wired PC and all wireless PCs.
5.10.2.0.4 Prevent a wireless PC from communicating with the wired network
Configure the following settings to prevent wireless PC3 from communicating with any device on the Ethernet:
•
Wired MAC Address: 00:00:00:00:00:00
•
Wired Mask: 00:00:00:00:00:00
