Course Description:

Knowing the fundamentals of the Wireshark® application and how to diagnose/troubleshoot 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 layered model approach to analyze the world of IP Networking.

The course is a combination of 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 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:

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
Understand how Wireshark can help to analyze network problems
