Command History
Usage Guidelines The removal of the dot1x mac-auth-bypass configuration from a port does not affect the authorization
or authentication state of a port. If the port is in unauthenticated state, it remains unauthenticated, and if
MAB is active, the authentication will revert back to the 802.1X Authenticator. If the port is authorized
with a MAC address, and the MAB configuration is removed the port remains authorized until
re-authentication takes place. When re-authentication occurs the MAC address is removed in favor of an
802.1X supplicant, which is detected on the wire.
Examples This example shows how to enable EAP MAC address authentication:
Switch(config-if)# dot1x mac-auth-bypass
Switch(config-if)#
eap (Optional) Specifies using EAP MAC address authentication.
Release Modification
12.2(31)SG Support for this command was introduced on the Catalyst 4500 series switch.
