Overview

Why Use Port-Based or User-Based Access Control?

Local Area Networks are often deployed in a way that allows unauthorized
clients to attach to network devices, or allows unauthorized users to get
access to unattended clients on a network. Also, the use of DHCP services and
zero configuration make access to networking services easily available. This
exposes the network to unauthorized use and malicious attacks. While access
to the network should be made easy, uncontrolled and unauthorized access is
usually not desirable. 802.1X simplifies security management by providing
access control along with the ability to control user profiles from up to three
RADIUS servers while allowing a given user to use the same entering valid
user credentials for access from multiple points within the network.

General Features

802.1X on the switches covered in this guide includes the following:
■ Switch operation as both an authenticator (for supplicants having a point-
to-point connection to the switch) and as a supplicant for point-to-point
connections to other 802.1X-aware switches.
• Authentication of 802.1X access using a RADIUS server and either the
EAP or CHAP protocol.
• Provision for enabling clients that do not have 802.1 supplicant soft-
ware to use the switch as a path for downloading the software and
initiating the authentication process (802.1X Open VLAN mode).
• User-Based access control option with support for up to 32 authenti-
cated clients per-port.
