Quick Look
Only network events can be analyzed in the Packet panel. The Packet panel lists each packet in the event. The list of packets is scrollable. When you scroll, the packet or text identification information as well as the Request and Response labels remain visible rather than scrolling out of view.
In Version 11.1 and later, you can use pagination controls to go backward and forward through the pages, go to a specific page, and select the number of packets to display per page (50, 100, 300, or 500).
Each packet is displayed with shading and highlighting to help identify common file patterns: significant header and payload bytes, hexadecimal and ascii bytes, and common file signatures. In addition, you can adjust the request/response display, and display or hide the packet summary.
Below is an example of the Packet panel (formerly known as Packet Analysis) with labels to identify features. For details and examples of each feature, see Analyze Events in the Events View.
| 1 | Options for exporting a network event. You can export a PCAP, all payloads, request payloads, or response payloads for deeper analysis and to share with others. |
| 2 | The option to identify common file signatures is activated by default. Common file signatures are highlighted in orange; hovering over the highlight reveals the file type. |
| 3 | The Shade Bytes option adds shading to identify the different hexadecimal bytes (00 to FF) using degrees of highlighting. |
| 4 | The option to display payloads only hides the packet headers, leaving more space for the payload. |
| 5 | The Overview panel information. |
| 6 | Significant bytes are highlighted in a blue background; as you move the cursor over the highlighting the meta data is displayed in a hover box. |
