CHAPTER 42
MAC Authentication Bypass
The MAC Authentication Bypass feature is a MAC-address-based authentication mechanism that allows
clients in a network to integrate with the Cisco Identity Based Networking Services (IBNS) and Network
Admission Control (NAC) strategy using the client MAC address. The MAC Authentication Bypass feature
is applicable to the following network environments:
•
Network environments in which a supplicant code is not available for a given client platform.
•
Network environments in which the end client configuration is not under administrative control, that
is, the IEEE 802.1X requests are not supported on these networks.
