MAC Filtering - 135
MAC Filtering
A Media Access Control (MAC) address is a hardware address that uniquely identifies each node of a
network. All IEEE 802 network devices share a common 48-bit MAC address format, usually displayed as
a string of 12 hexadecimal digits separated by colons, for example
FE:DC:BA:09:87:65
.
Each wireless network interface card (NIC) used by a wireless client has a unique MAC address.
You can control client access to your wireless network by switching on MAC Filtering and specifying a list
of approved MAC addresses. When MAC Filtering is on, only clients with approved MAC addresses can
access the network.
The following sections describe how to use MAC address filtering on the Professional Access Point:
