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. 1 X
("dot1X") protocol.
A port can be configured either as an 802. 1 X 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. 1 X supports Extensible Authentication Protocol
(EAP) over LANs (EAPOL) message exchanges between supplicants and
authenticators.
This section describes the commands you use to configure 802. 1 X operation on
the switch.
