XXX - add a brief description of H1 history

Example capture file
XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
A complete list of H1 display filter fields can be found in the display filter reference
Show only the H1 based traffic:
You cannot directly filter H1 protocols while capturing.
