percentage of received packets whose source addresses cannot be found in the forwarding table, in which case the Switch will broadcast the packet to all ports, negating many of the benefits of having a Switch.

Static forwarding entries are not affected by the aging time.

To set the Aging Time, enter the number in the MAC Address Aging Time field, and click on the “OK” button to save. The valid range is 30~1000 seconds. Default is 300 seconds.

4.7.6 802.1X Port-Based Network Access Control

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.
