As you may be aware, Wireshark is an incredibly useful freeware tool for capturing network traffic on a computer. 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.
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.
Continuing 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.
