13.3.1 Configuring MAC Address Filter
Your ZyAIR checks the MAC address of the wireless station device against a list of allowed or
denied MAC addresses. However, intruders could fake allowed MAC addresses so MAC-
based authentication is less secure than EAP authentication.
Follow the steps below to create the MAC address table on your ZyAIR.
Key 1 to Key 4 The WEP keys are used to encrypt data. Both the ZyAIR and the wireless stations must
use the same WEP key for data transmission.
If you chose
64-bit WEP in the WEP Encryption field, then enter any 5 ASCII characters
or 10 hexadecimal characters ("0-9", "A-F").
If you chose
128-bit WEP in the WEP Encryption field, then enter 13 ASCII characters or
26 hexadecimal characters ("0-9", "A-F").
Note: Enter “0x” before the key to denote a hexadecimal key. Don’t enter
“0x” before the key to denote an ASCII key.
Authen. Method Press [SPACE BAR] to select Auto , Open System Only or Shared Key Only and press
[ENTER].
This field is
N/A if WEP is not activated.
If WEP encryption is activated, the default setting is Auto .

Preamble Select a preamble type from the drop-down list menu. Choices are Long , Short and
Dynamic . The default setting is Long .
See the section on preamble for more information.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to associate
with the ZyAIR.
Select
802.11g Only to allow only IEEE 802.11g compliant WLAN devices to associate
with the ZyAIR.
Select
Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices to
associate with the ZyAIR. The transmission rate of your ZyAIR might be reduced.
Max. Frame Burst Enable Maximum Frame Burst to help eliminate collisions in mixed-mode networks
(networks with both IEEE 802.11g and IEEE 802.11b traffic) and enhance the
performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks. Maximum
Frame Burst sets the maximum time, in microseconds, that the ZyAIR transmits IEEE
802.11g wireless traffic only.
Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800 recommended).
Enter 0 to disable this feature.
VLAN ID Enter a number from 1 to 255 to define this VLAN group. At least one device in your
network must belong to this VLAN group in order to manage the ZyAIR.
Breathing LED Select Yes to enable the Breathing LED, also known as the ZyAIR LED.
The blue ZyAIR LED is on when the ZyAIR is on and blinks (or breaths) when data is being
transmitted to/from its wireless stations. Clear the check box to turn this LED off even
when the ZyAIR is on and data is being transmitted/received.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to confirm or ESC to cancel” to
save your configuration or press [ESC] to cancel and go back to the previous screen.
