InterfaceID – This property tells Wireshark which Network Interface it needs to use for the capture.How to Determine the Parameters for Custom Wireshark CapturesĬonfiguring the script is simple and it only requires setting five Wireshark properties and one command. However, if you are already familiar with how to use Wireshark’s graphical interface and run simple captures, feel free to continue with the rest of this post. That post will provide you with a great explanation on what Wireshark is and how to use it to troubleshoot network communications. If you haven't used Wireshark before and aren't familiar with the basics, we strongly suggest you first take a few minutes to read the Tech Support Corner: Using Wireshark as a Supplemental Troubleshooting Tool post. ĭo you ever find yourself in need of troubleshooting Network Traffic using Wireshark, but you are concern with at how much storage the captures will take on the system? Well, you are in luck because today, we will learn how to write a simple script for running custom Wireshark captures. Wireshark also provides options for specifying capture filters (for defining a smaller subset of data to be captured that you're interested in) or you can capture all traffic and apply a display filter to narrow down the traffic that is visible.Ĭontinuing our Tech Support Corner blog series, this blog post covers how to go even further using Wireshark by defining scripted custom Wireshark captures for specific use cases, which is helpful for capturing infrequent issues without wasting a lot of unnecessary hard drive space. Our support engineers find it to be invaluable for troubleshooting Ethernet communications issues, as it provides visibility into more than just the protocol data packets, including handshaking calls and responses. As you may be aware, Wireshark is an incredibly useful freeware tool for capturing network traffic on a computer.
