Adding a Switch to the Network
When using Wireshark, there are some potential limitations in monitoring traffic on
an Ethernet channel. A protocol analyzer can only decode the traffic that it receives.
Typically, networks use switches, and switches do not forward all traffic to all ports,
but instead attempt to only forward traffic to ports that should be receiving that
traffic. This means that only LonTalk/IP traffic that is broadcast, multicast, or sent
directly to the computer running Wireshark will be received and decoded by
Wireshark.
Adding a Hub to the Network
If you use a hub on your network, then all traffic received by that hub is forwarded to
all ports on the hub. This means that all traffic can be decoded by a computer
running Wireshark, regardless of the destination of the traffic. You can find a more
thorough discussion of hub traffic at
Reading the Wireshark Logs
You can use Wireshark filters to select packets to be logged or displayed, and you can
use Wireshark statistics reports to analyze displayed data. For more information on
using Wireshark, download the Wireshark documentation from
The Wireshark User's Guide is available in several formats,
you can browse it on the Web, download a zip file, or grab it as a PDF file.
