Configuring Device Information
This section provides all system operation and general information for configuring network security,
ports, Address tables, GARP, VLANs, Spanning Tree, Port Aggregation, and Multicast Support.
Configuring Network Security
The device enables network security through both Access Control Lists and Locked Ports. To open
the Network Security page select Switch → Network Security.
Network Security Overview
This section describes the network security features.
Port Based Authentication (802.1x)
Port based authentication enables authenticating system users on a per-port basis via a external
server. Only authenticated and approved system users can transmit and receive data. Ports are
authenticated via the RADIUS server using the Extensible Authentication Protocol (EAP).
Port Authentication includes:
•
Authenticators
— Specifies the port that is authenticated before permitting system access.
•
Supplicants
— Specifies host connected to the authenticated port requesting to access the system
services.
•
Authentication Server
— Specifies the external server, for example, the RADIUS server that
performs the authentication on behalf of the authenticator, and indicates whether the user is
authorized to access system services.
Port based authentication creates two access states:
•
Controlled Access
— Permits communication between the user and the system, if the user is
authorized.
•
Uncontrolled Access
— Permits uncontrolled communication regardless of the port state.
The device currently supports Port Based Authentication via RADIUS servers.
