![]() Using 802.1X, the authenticator (switch) is a facilitator that carries information received from the supplicant in EAPOL (EAP over LANs) frames to the authentication servers such as a Remote Authentication Dial-In Server (RADIUS) server running on Microsoft Network Policy Server. It is based on the Extensible Authentication Protocol (EAP). What is 802.1X authentication? This is an authentication based on the IEEE 802.1X protocol between the supplicant (client) and the authenticator (network access switch). ![]() Let’s take a how to configure Windows 10 for 802.1x user authentication. In this post, we will take a look at what is required on the Windows 10 side of things to get up and running with 802.1x authentication to allow interacting with an 802.1x compatible switch to provide policy-based networking and identity-driven network control. Extreme Networks has a really slick solution for applying policies at the port level that allow effectively microsegmenting devices at the physical port level and configuring an identity-based network that can exponentially increase security. There are many cool things you can do with this port level authentication for physical devices that are connected to a supported switch. In enterprise networking, many are familiar with 802.1x authentication mechanisms that allow performing authentication at the port level on a supported switch.
