= Hypertext Transfer Protocol version 2 (HTTP2)
Protocol dependencies
TCP: Typically, HTTP2 uses TCP as its transport protocol. The well known TCP port for HTTP2 traffic is 443 (and 80).
Wireshark
The HTTP2 dissector is partially functional (Support HPACK but missing continuation frame support...)
Example capture file

Display Filter
A complete list of HTTP2 display filter fields can be found in the display filter reference
Show only the HTTP2 based traffic: http2
Capture Filter
You cannot directly filter HTTP2 protocols while capturing. However, if you know the TCP port used (see above), you can filter on that one.
Capture only the HTTP2 traffic over the default port (443):
tcp port 443
