Why I have loss during capture data?

Hi everyone,
I'm working with Intel(R) Ethernet CNA x710 DA4 FH that has 4 ports and I want to capture high rate data (more than 3 Gb per second per port). First, I tested to capture 3.3 Gb rate data from one port. It was good without any loss. Fig.1 shows the CPU cores load. But when I want to capture data from two or more ports simultaneously, I have a lot of losses, also CPU load is just on one core. Figs 2-4 show CPU load for 2, 3, and 4 port data capturing respectively.
anyone can help me to distribute load on different cores? I think it can remove losses.
Or how can I capture data without loss?
I work by Windows server 2016 OS, WinPcap 4.1.3 to capture data, Visual studio 2013 and C program.
Fig.5 shows my Ethernet card feature.
Thank you in advance.

Hello Miladdona,


We sincerely apologize for the delay on this matter.


Please see below information for the response from our engineering team.


Just to confirm, you are having similar issues with SW 25.4? Did you revert the driver back to 25.2 after confirming that the latest driver did not help? Or are you still using the latest driver from 25.4


Since you are encountering an issue updating the Firmware using Version: 8.10 with error "Update not available"

Can you try the procedure posted on this forum but using 8.10 https://community.intel.com/t5/Ethernet-Products/Intel-X710-T2L-NVM-Update-to-7-3-Failing/td-p/66466...

Hello Miladdona,


You're welcome, appreciate your reply.


Can you also confirm if you are able to update the firmware to its latest version as we mentioned on our previous post?

Hi,

Thank you for your response.

I downloaded the new Non-Volatile Memory (NVM) Update Utility for Intel Ethernet Adapters 700 Series (Version 8.10) from the below link:
https://downloadcenter.intel.com/download/25790/Non-Volatile-Memory-NVM-Update-Utility-for-Intel-Eth...

and follow the steps that mentioned in this post:

https://community.intel.com/t5/Ethernet-Products/Intel-X710-T2L-NVM-Update-to-7-3-Failing/td-p/66466...


I mean after downloading NVM utility 8.10, I extracted it and open "nvmupdate.cfg" file as a text and add "EEPID" to "REPLACES" field and saved it.
After that I ran "nvmupdatew64e.exe" and got the results. You can see the results in Fig.1.
Just, there were different devices in "nvmupdate.cfg" file and I did the same for all. (add "EEPID" to "REPLACES" field). You can see a partial from my "nvmupdate.cfg" in Fig.2.

But, I still have loss.

Thank you in advance.
Best regards,
Miladdona

Hello Miladdona,

 

How are you today? 

 

Our engineering team would like to clarify the information below. We hope you don't mind sharing this with us. 

 

Is the C program you used was also installed on the same system with Windows Server 2016 and X710-DA4 adapter? Or is still installed on a different system connected on the server with x710-da4 and both systems are connected to switch?

 

Latest 25.5 driver package is now available for downloads. Will you be able to try it out and share the result with us after testing? 

Intel® Ethernet Adapter Complete Driver Pack Version: 25.5 (Latest)
https://downloadcenter.intel.com/download/22283/Intel-Ethernet-Adapter-Complete-Driver-Pack?product=...

 

Hoping to hear from you soon.
