After selecting the interface, you’ll be sent to Wireshark’s main window, where we can see a variety of options.

Option Bar

On the options bar there are 11 options such as a file, edit, view, go, capture, analyze, statistics, telephony, wireless, tools and help

The filter search toolbar, commonly known as the filter toolbar, is located beneath the toolbar. This toolbar will allow you to filter and search capture packets based on protocols, names, IP addresses, and other criteria.

A packet list pane, commonly known as the packets window, is located beneath the filter toolbar and displays all of the live collected packets.
