Intel C3558

  • Hi Guys,

    I have been tasked to explore options for pfsense using Intel C3558 series processor. What I need to know is that it comes with SOC based x553 NICs. Are those integrated when we say SOC?

    Lets say I don't want to use the integrated SOC based NICs. Can I add NICs of my own or I am limited to using the integrated ones?

    I have seen x553 is a converged access adapter which means it works on 1G and 10G modes and the drivers it uses are ix not igb like I am used to. Can anyone explain usually ix drivers are for 10G right or am I wrong here? Please correct me.

    Can these drivers be modified to work with 1G only?

    Lets say If I wish to use i350 AM-4 instead of the SOC based x553 what steps will I need to take make it happen? Please let me know.

    Automatic backwards compatible

    Buy one or if you already have, just plug in the PCIe slot...pfSense comes with all drivers needed and it's best to use Intel NIC.

    Yup that^.

    There is no problem running pfSense with C3K CPUs. It will use the built-in ix NICs at whatever speed they are configured for if they're present.
    Just add a card into the system if you want other NICs.

    Hi guys! Sorry for the delayed response as I had a family emergency.
    I have a system with CPU c3558 quadcore with SOC based Intel X553 NICs. When I install pfsense, NICs are not recognized. I don't get any sort of connectivity.

    I would like to know how can I overcome this problem? Is there a way to compile drivers for it and integrate with the pfsense kernel. Will the drivers persist upon reboot. I am aware if I reinstall from the drivers will need to be loaded all over again.

    Anyone has ever tried this method? I would like to know the method and steps to get started? I am looking forward to the response.

    Do the NICs appear in the output from pciconf -lv at the command line?

    Do you see the driver failing to attach in the boot log?


  • @stephenw10 I'll get the output of the command from shell and get back to you. I need to know how to check the boot log?

  • Netgate Administrator

    It's in /var/log/dmesg.boot

    Or just run dmesg if you've just booted.

  • Which version of PfSense are you trying to install?
    Have been using the same nic on a supermicro xeon d-1521 board for a couple of years now and haven't seen any problems so far with various versions of 2.4 or 2.4.5 and 2.5 snapshots either.

  • Netgate Administrator

    Yup, that's certainly what I would expect.
