About 802.1X
802.1X defines a client-server based access control and authentication protocol that restricts unauthorized
clients from connecting to a LAN through publicly accessible ports. The authentication server authenticates
each client connected to a Cisco NX-OS device port.
Until the client is authenticated, 802.1X access control allows only Extensible Authentication Protocol over
LAN (EAPOL) traffic through the port to which the client is connected. After authentication is successful,
normal traffic can pass through the port.
Device Roles
With 802.1X port-based authentication, the devices in the network have specific roles.
