Port-based access control provides a method for networks to control whether 
hosts can access services provided by a connected port. You can configure the 
switch to use port-based network access control based on the IEEE 802.1X 
(“dot1X”) protocol.

A port can be configured either as an 802.1X authenticator or a supplicant:

•

A supplicant is a port that requests access to the network. The supplicant 
provides credentials to the network that the another node on the network—
the authenticator—uses to request authentication from a server.

•

An authenticator is a port that must be authenticated before it permits other 
nodes on the network to use the services it provides access to. The 
authenticator relays supplicant requests and credentials to an 
authentication server, and authorizes or denies access to the supplicant.

In the authentication process, 802.1X supports Extensible Authentication Protocol 
(EAP) over LANs (EAPOL) message exchanges between supplicants and 
authenticators.

This section describes the commands you use to configure 802.1X operation on 
the switch.
