Explanation:
EAP Configuration for NAPs
EAP is a flexible request-response protocol for arbitrary authentication information (RFC
2284). EAP is layered on top of another protocol such as UDP, 802.1x, or RADIUS and
supports multiple authentication types:
PEAP (Protected EAP)
EAP-FAST
EAP-TLS (based on X.509 certificates)
EAP-MD5: Plain Password Hash (CHAP over EAP)
EAP-GTC: OTP Tokens
Note You can enable RADIUS Key Wrap attributes for PEAP, EAP-FAST and EAP-TLS
authentication.
The following extended EAP methods are available for NAC:
EAP-TLV: Carry posture credentials, adding posture AVPs, posture notifications.
Status Query: You can use this new EAP method for securely querying the status of a
peer without a full credential validation.
EAPoUDP: use of EAP over UDP for Layer 3 transport.
