What does this course tell?
(Please note that the following overview content is from the original platform)

Using Wireshark to identify and analyze ARP, ICMP, and DNS traffic is a great tool to add to a network engineer's toolkit. Many of the most easily corrected problems on a network can be solved by understanding proper operation of these protocols.
Network engineers can quickly become frustrated with unusual network performance issues. While most engineers are familiar with ARP and know how to clear a cache on a device, and they use ping regularly to troubleshoot networks, understanding both ARP and ICMP operation at the packet level will bring a new way to quickly solve network issues. In this course, Wireshark Traffic Analysis: Customizing the Interface, ARP, ICMP, and DNS, you will gain the ability to use Wireshark captures to detect and understand network issues causing performance problems. First, you will see how to customize the Wireshark interface, creating profiles for unique troubleshooting situations. Next, you will discover ARP operation, what it means, and how to use it to identify specific behaviors of network traffic. Finally, you will explore how to analyze ICMP types and codes in Wireshark, so you can use it to troubleshoot networks in a new way. When you are finished with this course, you will have the skills and knowledge of Wireshark protocol analysis needed to analyze and troubleshoot ARP, ICMP, and DNS traffic on your network.
