![]() ![]() In this example, we confine ourselves to a small network with no packet loss to speak of. In a future post I will cover using the utilities tc and iptables to simulate packet loss. This capture is the same type of capture I used in the post “ Using jperf and Wireshark to troubleshoot network issues“. To begin with, I ran a jperf session between a client and a server and used Wireshark to capture the packets. This can assist you in seeing whether there are any issues on the network such as dropped frames, timeouts or dropped connections. This post is about another nice feature of Wireshark, namely, the flow graph. I posted a few weeks ago about using Wireshark to inspect packets on your network. Scott Reeves demonstrates the flow graph feature of the Wireshark tool, which can help you check connections between client server, finding timeouts, re-transmitted frames, or dropped connections. Please remember to mark the replies as answers if they help and unmark them if they provide no help.Using the flow graph feature on Wireshark If you have feedback for TechNet Support, contact to your description, my understanding is that it prompts message "IP Checksum offload error" when running Wireshark. Please remember to mark the replies as answers if they help and unmark them if they provide no help. Detailed setting option you may contact the vendor.īesides, your question is mainly about Wireshark, if the problem still exits, it is better to contact the support/developer and confirm the problem, such as compliance about the OS version of Windows Server, update edition. Note that, TCP checksum offload is a function of your NIC and drivers. You may try to disable the settings(such as IPv4 Checksum Offload, Large Receive/Send Offload, TCP Checksum Offload) about TCP offload. Open network and sharing center – change adapter settings - right click the adapter and click properties - advanced. You have mentioned that “Configuring NIC under the Windows”, if you want change the setting about TCP checksum, you may follow the steps below: According to your description, my understanding is that it prompts message "IP Checksum offload error" when running Wireshark. ![]()
