As part of 802.1x, there are numerous EAP types that define the process for the secure transfer of data. The 802.1x standard mandates only the use of EAP but does not specify how it is implemented. The following RFC will provide you with some of the many versions of EAP types. RFC 2284, PPP EAP TLS Authentication Protocol: http://www.ietf.org/rfc/rfc2716.txt Note Specific subfunctions of EAP help to ensure the identity of the end device. They are Identity, Notification, NAK, and MD5-Challenge. You can learn about them in RFC 2284.
