Usage Information
The prerequisites for enabling MAB-only authentication on a port are:
• Enable 802.1X authentication globally on the switch and on the port (the dot1x
authentication command).
• Enable MAC authentication bypass on the port (the dot1x mac-auth-bypass
command).
In MAB-only authentication mode, a port authenticates using the host MAC
address even though 802.1x authentication 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.
