    Intel X710 (X710DA2) loop issue?

    x710

      Hi,

       

      We order an Intel X710DA2 from Provantage and SFPs from Amazon.

      The NIC and accompanied SFPs work fine with full speed (10 Gbps) when connecting with other NIC Ports.

       

      The Issue we need to ask here is when we loop the two ports of that X710DA2 together (connect the cable from port 1 to port 2 on same X710DA), the port status show "Cable Unplugged", of course the Intel IOUtil show IO not Enable:

      NIC B/D/FVen-Dev   MAC      IO  Branding string

      === ======== ========= ============ === =======================================

      1) 02/00/00 8086-1572  NA  Intel(R) Ethernet Converged Network Adapter X710-

      2) 02/00/01 8086-1572  NA  Intel(R) Ethernet Controller X710 for 10GbE SFP+

       

      Also, DPDK (1.8) testcmd shows only 1Gbps link connection between them.

      Checking link statuses...

      Port 0 Link Up - speed 1000 Mbps - full-duplex

      Please explain to us about this unexpected situation.

          Hi x710,

          Thank you for the post, Just to double check looping the  two ports of that X710DA, are you referring to connecting the cable from port 1 to port 2 of the same X710DA? This kind of connection yields limited performance ..

            Yep, we connect the cable from port 1 to port 2 on same X710DA. Is there any document/note refer to this limited performance case?

                        We would like to understand more about the network card and your system settings.  Please answer details below:

                         

                        1. Serial number and part number from the white sticker.  (See adapter photo here)

                        2. Is the CentOS running on a bare metal system, or in a virtual machine.

                            If in a VM, what the Virtual Host (ie VMWare).

                        3. How long is the fiber cable?

                        4. What is the current version of the NVM on the adapter?

                         

                        We look forward to your reply.

                                  Upon checking, we think that its the driver problem or the driver is not loaded.  Please check if you are using the latest driver.

                                  The latest driver is available for download here.

                                   

                                  Hope this help resolve the issue.
