Course Overview

Course in a Nutshell

This course, one of a series of our courses related to Carrier Ethernet, will cover the basics of OA&M for Ethernet service providers as well as the impact of lower layer protocol issues on the Quality of Service (QoS) of the Ethernet service and higher layer protocols. Upon course conclusion, you will have a fundamental understanding of the IEEE 802.3ah and 802.1ag standards, the ITU-T Y.1731 standards and related protocols and standards.


Customize It!

We can tailor this course to suit the needs of audiences such as engineers, sales engineers, and marketing/sales. Also, a three-day version of this course, focusing on the larger subject of Wide Area and Carrier Ethernet design, troubleshooting and problem resolution, is available. This 3-day course takes a deeper dive into frame structures, design logic of the protocol and includes hands-on lab exercises designed to develop a bit level understanding of the frame structure and protocol operations. The course can also be extended to include an in-depth discussion of the QoS issues.

Audience / Prerequisites

Aimed At

Engineers and others who require an overview of Ethernet OA&M. While the second day of this course will be accessible to technical personnel only, less technical personnel such as sales/marketing staff may benefit from the subject overview presented in the first half day.



Basic knowledge of the network layers and protocol operations.

  • "The best [instructor] I ever had. I want to congratulate you on having an instructor of Jim's stature. He adjusted himself completely to the wide range of knowledge in the class, took a dry subject and spiced it up with his deep knowledge of the industry and standards, to the level where everyone not only learned but enjoyed the experience as well. I look forward to hosting him again." - Neer Ziskind, Sr. Director – Product Mgt., BridgeWave
  • "Excellent overview of not only OAM but also of how Ethernet works. Instructor well liked, very helpful, and very knowledgeable in not only main subject but could also relate to the challenges we face as manufacturers in implementing OAM in our products. Good mix of real-world experience." – JS, VP of Marketing, US Gigabit Wireless Ethernet Manufacturer
