The document describes how to filter captured network packets to match the description provided in the metadata. Specifically, it discusses a scenario where a user launches a music sharing application called iMesh on a PC, browses for songs, selects a song, and sends it. To verify the captured packets match this scenario, the document instructs to select the conversation in Wireshark that shows browsing data, selecting a song, and sending song information, then follow the stream to check it matches the described content.
