What Students are Saying about This Class:

“Andrew is a great instructor. I thoroughly enjoyed the Wireshark for Data Center course. His knowledge in this area and his ability to relay tips made this course well worth the time. I hope that I have the opportunity to take another course from him.”
“It was a great overall experience! I used Wireshark but never had a formal training about it and this one really helped me learned a lot about the tool. We deal with network testing and automation at an enterprise level in the team and so having to get this type of training is very valuable in our daily tasks and troubleshooting of issues. The [Instructor] was great! Hopefully I’ll be able to avail more related training in the future. Thank you!”
“Class/Instructor is great, I can certainly apply what I’ve learned to my work.”
“Instructor presented materials professionally and complete overview of the material.”
“Overall I was very please[d] with both the content and delivery method of the course. Also, the instructor was very knowledgeable and knew his subject matter well. I’d recommend this course to others.”

Course Description:

Knowing the fundamentals of the Wireshark® application and how to diagnose/troubleshoot the data center network with a focus on iSCSI and Fiber Channel over the TCP/IP protocol suite is vital to anyone who is in the networking field today. 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 help me as iSCSI and Fiber Channel are transported in IP?”
“How do I maximize my network performance and understand TCP/IP networking?”

Course Objectives:

The objectives of this 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
