Prerequisite knowledge

  • A basic understanding of IP networking

What you'll learn

  • Understand why, of the various methods that can be used to manage client access to networks, 802.1X offers the most sophisticated control and how its benefits can be realized on a wired network


The IEEE 802.1X standard defines a method to grant access to network ports only to authenticated client devices. Pat Parseghian shares the story of what a small, determined team did to make wired 802.1X a reality on Google’s enterprise network.

Pat describes the design and implementation of wired 802.1x on Google’s large enterprise intranet (hundreds of thousands of ports, spanning more than 350 offices in over 50 countries). The network design accommodates a diversity of devices and operating systems. Pat then covers the challenges the team resolved in rolling out 802.1X on a live, established network, including network and device configuration, authentication methods, solutions for noncompliant devices (legacy and experimental), inventory management, user education, and good, old-fashioned bugs.
