;'''EAP-MD5''':
'''802.1X,''' Port-Based Network Control, is an IEEE standard. The standard allows LAN devices (wired network cabling!<ref>The standard refers to 802 LANs as a whole, including shared media such as 802.11 WLANs. However, only 802.3 LANs are targeted by the functionality discussed in this article.</ref>) to perform an authentication handshake within the 802.3 link layer (Ethernet).
The authentication is encapsulated within EAP over LAN (EAPOL) frames. No other traffic, except EAPOL is allowed prior to a successful authentication<ref>It is an authenticator's task to guarantee that non-EAPOL traffic won't be forwarded before an authentication succeeded.</ref><ref>802.1X must not be considered a bullet-proof security mechanism, since all traffic following the authentication phase is not authenticated.</ref>.
 
The standard specifies the following parties participating in an 802.1X authentication:
* Supplicant: The party supplying credentials towards an authenticator on the other side of a point-to-point link. An IP phone fulfills a supplicant's role.
** innovaphones' IP phones are configured to support pass-through of EAPOL messages. A PC attached to the PC-port of a phone may also become a supplicant and may 802.1X-authenticate independently and separately<ref>Major authenticators do support multi-host authentication</ref>.
* Authenticator: The party facilitating the authentication. A switch will usually be the authenticator.
* Authentication Server: The party providing the authentication service to the authenticator. The 802.1X standard mentions a RADIUS server to be an authentication server.

EAP-MD5
  • User Enter the user/identity to authenticate with.
  • Password Enter the shared secret for the MD5 challenge/response handshake.
EAP-TLS
  • User Enter the user/identity[1] to be sent within the EAP Identity request.[2]
  • Password Enter arbitrary content.[2]
  • General/Certificates/Device Certificate

Notes

  1. ↑ EAP-TLS doesn't mandate that identity to necessarily be the same as the certificates subject/CN
  2. ↑ 2.0 2.1 A non-empty user/password just serves as an "on"-switch
