percentage of received packets whose source addresses cannot be found in the forwarding table, in which case

4.7.6.1 Theory
Understanding IEEE 802.1X Port-Based Authentication
The IEEE 802.1X standard 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 switch port before making available any services offered by the Switch or
the LAN.
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
• Authentication Initiation and Message Exchange
• Ports in Authorized and Unauthorized States
