Information
The prerequisites for enabling MAB-only authentication on a port are:
• 802.1X authentication must be enabled globally on the switch and on the port
(dot1x authentication command).
• MAC authentication bypass must be enabled on the port (dot1x
mac-auth-bypass command).
In MAB-only authentication mode, a port authenticates using the host MAC address even
though 802.1xauthentication is enabled. If the MAB-only authentication fails, the host is
placed in the guest VLAN (if configured).
To disable MAB-only authentication on a port, enter the no dot1x auth-type mab-only
command.
