Product Description

In this hands-on Troubleshooting TCP/IP Networks with Wireshark course, you will receive in-depth training on Wireshark® and TCP/IP communications analysis. You will learn to use Wireshark to identify the most common causes of performance problems in TCP/IP communications. You will develop a thorough understanding of how to use Wireshark efficiently to spot the primary sources of network performance problems, and you will prepare for the latest Wireshark Certified Network Analyst (WCNA) certification exam.

Topics you will cover in this course include:

  • Traffic capturing techniques and analyzer placement
  • Traffic filtering (capture/display)
  • Customized profiles creation
  • Coloring rules, graphing, field interpretations, and functionality of key TCP/IP communications
  • Normal behavior of ARP, DNS, IP, TCP, UDP, ICMP, and HTTP/HTTPS
  • Latency issue identification
  • Connection establishment concerns
  • Service refusals
  • Common indications of reconnaissance processes and breached hosts

This course includes the official Wireshark study guide to help you prepare for the WCNA certification exam.

Please bring your own laptop loaded with Wireshark to class. You may download Wireshark for free at
