Examine A Captured Packet Using Wireshark
Search Networking, April 17th, 2023
Wireshark is a useful tool for capturing network traffic data. Network pros can make the most of the tool by analyzing captured packets to see what that data means for troubleshooting.
Capturing network traffic with tools such as Wireshark and tcpdump is fairly straightforward. Where many administrators run into trouble is understanding what they've captured.
This article explains the primary components of captured data and relates this information to the TCP/IP model. The article's purpose is not covering how to use Wireshark or its features and options. I provide only the basic steps to capture packets -- enough for you to grab a packet and apply the interpretive information provided throughout.
