Packet Details - this shows the details of a selected packet Wireshark is usually able to determine the protocol of each packet and will show a detailed view of the individual details in the packet, such as the MAC addresses (layer 2), IP address level source and destination addresses (layer 3) and the packet data such as the details of an HTTP request Packet List - this lists the packets received, clicking on a packet here will show it in the Packet Details and Packet Bytes sections There are three elements to Wireshark's display of packets: Once a packet capture has been started, it will show traffic like this. Selecting interfaces in this window and clicking Start would start the packet capture. Low-level packet analysis such as observing network issues usually does not benefit from these facilities. It is recommended to untick the Name Resolution options as this alters some values in the packet capture file to make it easier to read for high-level packet analysis. Otherwise Wireshark will discard packets not intended for the PC doing the packet capture.
