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 802.1xauthentication 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.
