The important points covered in this chapter included picking an optimal capture point, selecting between TAPs and mirrored/SPAN ports, Wireshark's capture filters and options, verifying a good capture, using Wireshark's Conversation windows and display filters to isolate packets of interest, creating Filter Expression Buttons, marking and ignoring packets, and saving the filtered traffic for later or more detailed analysis.

In the next chapter, we'll cover the rest of Wireshark's basic packet analysis features.
