Wireshark is capable of dissecting over 700 protocols. To see a list of protocols in the capture, go to Statistics, and then Protocol Hierarchy, which will provide a list of what protocols appear in the capture. As with many other options, within Protocol Hierarchy, you can apply a filter and create your subset, as shown in the following screenshot:
Protocol hierarchy—Apply as Filter
In addition, if you know the protocol you want to review, you can use a display filter and enter a specific protocol and use that as your subset.
One of the common ways of examining traffic is by examining a particular traffic stream. In the final segment, we will see what elements of a capture we can view by using the follow the stream feature.
