802.1X authentication

ICX devices support the IEEE 802.1X standard for authenticating devices attached to LAN ports. Using 802.1X, you can configure an ICX device to grant access to a port based on information supplied by a client to an authentication server.

When a user logs in to a network that uses 802.1X, the ICX device grants (or does not grant) access to network services after the user is authenticated by an authentication server. The user-based authentication in 802.1X provides an alternative to granting network access based on a user IP address, MAC address, or subnetwork.

The ICX implementation of 802.1X supports the following RFCs:

  • RFC 2284 PPP Extensible Authentication Protocol (EAP)
  • RFC 2865 Remote Authentication Dial In User Service (RADIUS)
  • RFC 2869 RADIUS Extensions
