Which mechanism can be used to enforce network access authentication against an AAA server if the endpoint does not support the 802.1X supplicant functionality?
If an endpoint does not support 802.1X supplicant functionality, MAC Authentication Bypass (MAB) can be used to enforce network access authentication against an AAA server. MAB operates by using the MAC address of the device as a proxy for authentication, allowing devices that cannot run 802.1X to still be authenticated and granted network access.
