Abstract
According to one embodiment, a method for removing authentication of a supplicant includes monitoring communication between the supplicant and an authenticator. The method also includes determining, based on the monitored communication, the MAC address for the supplicant and an attachment port of the supplicant to the intermediate network device disposed between the supplicant and the authenticator through which the monitored communication occurs. The method also includes determining that the supplicant no longer has a link connection with the intermediate network device, and in response, sending via the intermediate network device a logoff message having a spoofed source address of the supplicant to the authenticator.
