Configuring 1 PPS in Intel® Ethernet Network Adapter XXV710-DA2T

Hi,

   We are using Intel® Ethernet Network Adapter XXV710-DA2T. We configured PTP boundary clock functionality. i.e one NIC port is  configured as slave and another one as a master. 

[PTP Grand master(1G eth ptp broadcast msg)-->Huawei Cloud Engine 6865, eth switch with 1G/10G port(25G network port+optical fiber)--> Server  NIC port (25G slave port)].

We are able to see PTP packets coming out of master port and synchronized to grand master. But we are unable to see 1 PPS from SMA port(checked both SMA port). How to enable 1 PPS from SMA port. Is there any configuration required for SMA port?

 

Thanks& Regards

Dinesha

Hello Dinesha,


Thank you for posting in Intel Ethernet Communities. 


For us to further check the issue, please provide the following details.


  1. What is your OS and its version?
  2. Can you share the link of your latest driver?
  3. If you are using a PCIe network card, please provide photos of the card on both sides focusing on the markings.
  4. Can you explain further explain the guide that you need regarding the SMA port?


If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.


Best regards,

Hi @Mike_Intel ,

Please find the details:

  1. Centos, version 7.6
  2. Driver: https://downloadcenter.intel.com/download/24411/Intel-Network-Adapter-Driver-for-PCIe-40-Gigabit-Eth...

          Refer image: NIC_drver_Version.PNG

  1. NIC card is already installed on server. We don't have full photo. Refer image: NIC_card_image.PNG

4.

  • We need derive the 1PPS signal at SMA port from PTP Packets available at NIC card.
  • We need to measure 1 PPS output at SMA, currently we are not seeing any output at SMA port.
  • In Solution brief doc it is mentioned that “Configuration of the SDPs/GPIOs required”. How to do it? Refer image: SMA_config.PNG
  • Our Setup is Boundary Clock Functionality. refer image: 1_PPS_setup.PNG  (Which is available on 5 page of Intel Solution brief of “Meeting 5G Edge Clock Synchronization Challenges with Hardware-Enhanced Precision Time Protocol (PTP)” documents.

Hi Michael,

We are trying to get 1  PPS out from SMA pins provided on XXV710-DA2T.  Please provide detailed information on "User-configurable I/O pins drive the SMAs and provide built-in timing coordination between ports".

Hello Dinesha,


For us to check the steps, can you share the Solution brief doc that you are following.

We would also appreciate if you can provide the other markings of the card for us to validate the card.

You can refer to this link for the markings that we are looking for in the Network card:

Hello Dinesha,

 

I'm also looking for this user guide manual and can't find it.

Do you have a download link that you can share with me?

Or please share how you managed to configure the SMA outputs.

 

Thanks a lot!

Christian
