Course Description:

Knowing the fundamentals of the Wireshark® application and how to diagnose/troubleshoot packets on the network, with a focus on the TCP/IP protocol suite is vital to anyone who is in the networking field today, whether it be Service Provider level or Enterprise level. This insightful and revealing course has been designed to focus on the packets using layered model approach to analyze the world of IP Networking.

The course is a combination of Wireshark knowledge training, systems analysis, with hands-on exercises using the Wireshark™ application, backed by CellStream’s experience in networking over the last 25 years, revealing the details and capabilities in a swift, comprehensive, and understandable way.

  • “What is Wireshark and why it matters?”
  • “What is the best way to set up Wireshark?
  • “What must I know about troubleshooting with Wireshark that will impact my network?”
  • “How does using trace analysis in Wireshark work?”
  • “How do I maximize my network performance and understand IP networking?”

Course Objectives:

The objectives of the course are:

  1. Develop a “hands-on” skill set targeted at using Wireshark with the layered network protocol stack in the following key areas:Master the layered networking model, and the analysis of the TCP/IP suite of protocols
    • Layer 1: Physical Interfaces
    • Layer 2: Ethernet
    • Layer 3: IPv4
    • Layer 4: UDP and TCP
  2. Understand how Wireshark can help to analyze network problems
    • Learn Wireshark shortcuts, Filtering, and Profiles
    • Leverage Wireshark capabilities to maximize the tool usage
  3. Comprehend how Wireshark can be used in security analysis and monitoring
  4. Define the Wireshark interface, features and functions
  5. Discover the details of how Wireshark works and behaves
  6. Illuminate and explore the communications protocols that Wireshark exposes and analyzes
  7. Reveal what Wireshark features enables us to analyze network issues, and perform maintenance


The target audience for this course is anyone in Internet Sales, Marketing, Engineering, Test, Customer Support, Technical Marketing, that requires a solid and complete understanding of the fundamental operations of Wireshark that can be applied to their job function.

Ideal candidates are:

  • Sales and Technical Marketing professionals that deal with the Internet

Course Prerequisites:

This course is designed to appeal to anyone needing the skills and knowledge to use Wireshark. The ideal student will have some experience in networking and operations, however no prior knowledge is necessary.

All students must attend with a lap-top computer running Windows, MAC OSX, or Linux operating systems.

If the course is held at a classroom where computers are available, the Lap-top computer may not be required.

Class size is limited to 20 students.

Course Materials:

Students will be provided with a PDF Course Student Guide. Also, access to analysis captures will be provided via the Online School of Network Science.
