Introduction
Wireshark is a free and open-source packet analyzer for IP networks. It is used for
network troubleshooting and analysis. The IzoT Plug-in for Wireshark enables
Wireshark to decode LonTalk/IP packets.
You can use the IzoT Plug-in for Wireshark to monitor LonTalk/IP traffic on a LAN
channel. You can also use the IzoT Plug-in for Wireshark to monitor LonTalk/IP
traffic on an FT channel if you have an IzoT Router that is configured as a repeater
and is attached to both your LAN and your FT channel, and if you have a hub
connecting your computer and your IzoT Router. The IzoT Router is configured as a
repeater by default. When operating as a repeater, the IzoT Router forwards all
packets on the FT channel to the LAN channel.
You can configure an IzoT Router to operate as a configured or learning router using
the IzoT Commissioning Tool. If the IzoT Router is operating as a configured or
learning router, it will not forward all packets on the FT channel to the LAN channel,
and as a result, you will not see all FT traffic in Wireshark. If you are using the IzoT
Commissioning Tool to commission an IzoT Router, change the operating mode to be
a repeater when you are using Wireshark to troubleshoot or analyze the FT channel.
You can change the operating mode back to a configured or learning router when you
are not using Wireshark.

default Wireshark Plugs folder is C:\Program
Files\Wireshark\Plugins\1.10.6, where 1.10.6 is the version of Wireshark you
have downloaded. The WireShark Plugin folder comes with DLLs compiled for
both 32-bit and 64-bit Windows. Use the ones that match your installation.
Monitoring Packets
Once you have set up Wireshark, you can monitor LonTalk/IP traffic. If you have
LonTalk/IP-FT devices and an IzoT Router connecting your FT channel to a LAN,
packets will flow from FT devices, through the IzoT Router, over the Ethernet LAN
and to your computer. The red line shows the flow of the packets.
