Wireshark Functionality and Fundamentals
Learn to use Wireshark efficiently and effectively by placing your analyzer in an ideal location to capture traffic (even on a switched network). Learn to focus on key traffic using capture filters and display filters. Graph
traffic, use navigation and colorization techniques and time values to easily spot network problems. Customize your Wireshark system and use the Expert system to identify problem areas. Learn how tshark, editcap, capinfos and other command-line tools work and test yourself by completing lab exercises.
