4.4.5 802.1X Configuration
The IEEE 802.1X standard provides a port-based network access control and authentication
protocol that prevents unauthorized devices from connecting to a LAN through accessible switch
ports. Before services are made available to clients connecting to a VLAN, clients that are 802.1X-
complaint should successfully authenticate with the authentication server.
Initially, ports are in the authorized state which means that ingress and egress traffic are not
allowed to pass through except 802.1X protocol traffic. When the authentication is successful with
the authentication server, traffic from clients can flow normally through a port. If authentication fails,
ports remain in unauthorized state but retries can be made until access is granted.
Click the folder 802.1X Configuration from the Switch Management menu and then three
options will be displayed as follows.
1. 802.1X System Settings: Set up system 802.1X RADIUS IP, RADIUS Secret,
Reauthentication, EAP Timeout, and so on.
2. 802.1X Port Admin State: Set up the port authorization state.
3. 802.1X Port Reauthenticate: Set up the port reatentication.
