We'll go over how to filter traffic in data fields within packets, how to create columns on specific fields in our data packets and to sort them, and filter with these more hidden methods that you may not have noticed yet.
We'll go to our packet capture, opening up https://www.cisco.com/. And what we'll do is expand the section that gives us the details of our packet. We'll scroll down and find a packet that we wish to investigate a bit more.
