Abstract:
Embodiments herein describe disconnecting, by an access node, a first device having a first media access control (MAC) address due to a network violation and receiving, by the access node, information about a second device having a second MAC address different from the first MAC address. In one embodiment, the information is generated by a certificate server based on a token generated by the second device. Further, when the access node determines, based on the information, that the second device is the first device, the access node denies a connection request from the second device.
