MAC Authentication Bypass (MAB)

← All glossary terms Jump to M

MAC Authentication Bypass (MAB) – A fallback authentication method for devices that cannot perform 802.1X, in which the switch sends the endpoint's MAC address to a RADIUS server as its credentials, placing the device in an interim segment until authentication completes.
