802.1X Authentication Using EAP

  • Switches can use IEEE 802.1X to perform user authentication.
  • User authentication requires the user to supply a username & password, verified by a RADIUS server, before the switch will enable the switch port for normal user traffic.
  • IEEE 8802.1X defines some of the LAN user authentication, but it also uses the Extensible Authentication Protocol (EAP).
  • EAP: an internet standard (RFC 3748), as the underlying protocol used for authentication.
  • EAP also provides One-time passwords (OTPs).
