10.1 Overview

This chapter describes the IEEE 802.1x authentication method.
Port authentication is a way to validate access to ports on the MES-2110 to clients
based on an external server (authentication server). The MES-2110 supports the
following method for port authentication:
• IEEE 802.1x
username and password provided by the user.
IEEE 802.1x authentication uses the RADIUS (Remote Authentication Dial In User
Service, RFC 2138, 2139) protocol to validate users. See
for more information on configuring your RADIUS server settings.

10.1.1 IEEE 802.1x Authentication

The following figure illustrates how a client connecting to a IEEE 802.1x
authentication enabled port goes through a validation process. The MES-2110
prompts the client for login information in the form of a user name and password.
When the client provides the login credentials, the MES-2110 sends an
1. At the time of writing, IEEE 802.1x is not supported by all operating systems. See your operating system
documentation. If your operating system does not support 802.1x, then you may need to install 802.1x client
software.
