Syntax dot1x auth-type mab-only Defaults Disabled Command Modes INTERFACE Command History Version 8.4.2.1 Introduced on the C-Series and S-Series Usage 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.
