Wireshark Traffic Analysis: Customizing the Interface, ARP, ICMP, and DNS

Network engineers can easily become frustrated by unusual network performance issues. Although most network engineers are familiar with ARP, they also know how to clear a cache from a device. They use ping frequently to troubleshoot networks. Understanding both ARP operation at the packet level and ICMP operation will help to solve network problems quickly. This course, Wireshark Traffic Analysis - Customizing the Interface and ICMP, will teach you how to use Wireshark captures in order to identify and solve network problems that cause performance problems. You will first learn how to customize Wireshark's interface and create profiles for specific troubleshooting situations. Next, you'll learn about ARP operation and what it is, as well as how it can be used to detect specific network traffic behaviors. You will also learn how to use Wireshark to analyze ICMP codes and types. This will allow you to solve network problems in a new manner. This course will equip you with the knowledge and skills to troubleshoot ARP and ICMP traffic in Wireshark.
