Using Wireshark to Troubleshoot Network Connectivity Issues: Expert Infos
In addition to the “Follow TCP Stream,” “Decode As,” and “IO Graphs” features, Wireshark also includes a tool called “Expert Infos” that provides valuable information and insights about the packets being captured.
To use the “Expert Infos” feature, simply select the “Statistics” menu and then choose “Expert Infos.” This will open a new window that displays a list of all the packets being captured, along with any expert infos that are available.
Expert infos are messages generated by Wireshark that provide additional information about the packets being captured. There are three levels of expert infos: “Notes,” “Warnings,” and “Errors.” Notes provide general information about the packets, warnings indicate potential problems with the packets, and errors indicate serious problems with the packets.
You can use the “Expert Infos” feature to identify any issues with the packets being captured, such as problems with the protocol being used or errors in the packet contents. By using the “Expert Infos” feature in combination with other diagnostic tools, such as the “Follow TCP Stream” and “IO Graphs” features, you can gain a deeper understanding of the traffic on your network and identify potential problems.
