The next few sections describe the installation and usage of the PLUS dissector for Wireshark.

1. Download and install a recent version of Wireshark.
2. Open Wireshark.
3. Looking for the path to the plugins in Wireshark by menu Help > About Wireshark > Folders.
4. Open or create the folder for the Personal Plugins, got from the step before.
5. Copy the Lua script plus.lua for the PLUS Wireshark dissector into the Personal Plugins folder.
6. Restart Wireshark to activate the plugin. No error message at start may appear.
7. To check the activation of the plugin, open menu Help > About Wireshark > Plugins and search for the plus.lua plugin.

It is the same procedure as in the section before, but instead of copy the Lua script plus.lua, take the file plus_quic.lua.

Actually, the dissection in plus_quic.lua is hardcoded to dissect the next layer always as QUIC, even when there isn't QUIC.

Dissectors plus.lua and plus_quic.lua can't be enabled at the same time.

The dissector is looking for the magic id of the PLUS layer. If the magic id 0xd8007ff is present, the dissector is automatically applied on the packet, independent of the UDP port.

To manually dissect a packet as a PLUS packet, make a right click on a packet and choose Decode as.... Search for the PLUS protocol and set it there.

The following filter criteria can be applied as display or capture filters for the fields of PLUS:
