23.4.1 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.
1 From the main menu, enter 3 to open Menu 3 – LAN Setup .
Key 1 to Key 4 The WEP keys are used to encrypt data. Both the ZyAIR and the wireless sta-
tions 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
