Accton Technology ES3528M-SFP manual 802.1X Port Authentication

4 Command Line Interface

Command Usage

•If you enable port security, the switch stops learning new MAC addresses on the specified port when it has reached a configured maximum number. Only incoming traffic with source addresses already stored in the dynamic or static address table will be accepted.

•First use the port security max-mac-countcommand to set the number of addresses, and then use the port security command to enable security on the port.

•Use the no port security max-mac-countcommand to disable port security and reset the maximum number of addresses to the default.

•You can also manually add secure addresses with the mac-address-table static command.

•A secure port has the following restrictions:

-Cannot use port monitoring.

-Cannot be a multi-VLAN port.

-Cannot be connected to a network interconnection device.

-Cannot be a trunk port.

•If a port is disabled due to a security violation, it must be manually re-enabled using the no shutdown command.

Example

The following example enables port security for port 5, and sets the response to a security violation to issue a trap message:

Console(config)#interface ethernet 1/5

Console(config-if)#port security action trap

802.1X Port Authentication

The switch supports IEEE 802.1X (dot1x) port-based access control that prevents unauthorized access to the network by requiring users to first submit credentials for authentication. Client authentication is controlled centrally by a RADIUS server using EAP (Extensible Authentication Protocol).
