      what if i put a cat5e cable on mine to test at which speed it connect ?
      do you think it can only go from 1000 to 10gb under freebsd ?

        @stephenw10 Yes, here’s the ARK page: https://ark.intel.com/content/www/us/en/ark/products/88209/intel-ethernet-converged-network-adapter-x550-t2.html

        It’s been in my system since 2017, works fine at 1G and 10G.

        You can see it supports 2.5G and 5G. Just wondering if anyone has tried it with either standard.

            The only reference I see for 2.5Gbps even in the most recent ix driver is for 2500base-KX like we use for the internal link in the XG-7100, where no PHY exists:

              AFAIK NBASE-T for X550 is supported only for Windows and Linux OSes, moreover, on release NBASE-T was stated only for Linux by INTEL ARK.
              I've been running into the same issue with speeds and same card on FreeBSD and the solution was to place the cheapest unmanaged switch with NBASE-T supported, but the other end must support NBASE-T speed switching and you should manually select the desired speed or you need the managed switch.

                this is how it looks when runing at 2.5gbps. it seems to work fine was passing traffic, but has that scary unknown on ui. also still not able to select 2.5g/5g as listed under linux drivers by intel ARK for x550 specs. maybe its not been updated yet under pfsense.

                  Interesting. The other end shows it linked at 2.5G though?

                    Just re-tested it also.
                    I can confirm that selecting on the other end speeds below 10G is now working and yes, it's "unknown" mode on pfSense side. But I do not think there is anything to do with that since Intel driver does not report any speed, not pfSense.

                      @stephenw10 yes , i had to use a realtek 2.5g on a new board because i could not get x550 to change to 2.5g under PFsense or on the other side on windows system. it would be nice if PFsense suported 2.5 and 5g as selectable on its end if posible. idk where there is a hiccup in support, intel - bsd - pfsense. intel says under linux driver it should be setectable so idk,

                      thank you for keeping an eye on this issue.

                        under windows driver nbase t is only for auto-negotiating depending on link partner. but under Linux it should be fully supported and select-able. unless i am missing something.

                          If Intel says it's Linux only then that's probably true since they write the FreeBSD drivers themselves. There is probably nothing much we can do about that but wait for an update.
                          If the driver shows it as selectable then pfSense should also show that, the values from the driver are just passed through.

                            so even its not user select-able under BSD why is the driver seeing the current state as unknown. it work at 2.5/5 with auto negotiating when at link partner request under every other OS and displays it under ui and driver but its not displaying the current state under BSD. the HW support is there but the driver just does not know what is going on ?

                            i don't have a spare box up atm so i can just test on windows and pfsense(bsd)

                            here is X550 under windows driver connecting to the same realtek 2.5 board working and displaying fine. only the user selectablity to NBase-t is limited to linux. auto negotiating to nbase-t should be working on all drivers and os, should be displayed on ui.

                              Pretty much, yeah. The driver in FreeBSD 11.3 / pfSense 2.4.5 cannot return a link speed of 2.5G or 5G but it seemingly can show unknown.
                              The most recent drivers will be in FreeBSD 12 or those Intel offers for download.

                              Try a pfSense 2.5 snapshot, currenntly based on 12-rel. Or a newer FreeBSD image.

                                same in 2.5.0 :( definitely an FreeBSD/PFsense driver only issue . tested with Ubuntu bootable usb as well. as with windows it displays and auto negotiates at 2.5g just fine, i may test under newest FreeBSD tomorrow on the pfsense box it self.

                                  Mine was always 2.5. Definitely FreeBSD/Intel issue, nothing to do on pfSense side. But at least it works now and this should not be a problem anyway.

                                    Even the latest driver from Intel does not list 2.5G or 5G link speeds.

                                      This is the same driver we have in pfSense 2.5.0. Don't know are there any plans to implement full support for NBASE-T or not, can't find anything about it on FreeBSD side.

                                        Installed a Netgear CM2000 modem today. It's a DOCSIS 3.1 modem with a single 2.5GBASE-T port. The modem reports a 2.5G connection and pfSense reports "Unknown" as @WanTime showed earlier. I also see "<rxpause,txpause>" but it does not affect the connection as far as I can tell.

                                        I'm getting an aggregate bandwidth of about 1.2 Gbps between devices so Comcast is overprovisioning my gigabit service. Upload is still terrible however.

                                          Can anyone recommend a 1-port and/or 2-port low profile card?

                                            Just another data point:

                                            pfsense 2.5.1-RELEASE (amd64)

                                            Intel X550-T2 connected to the 2.5Gb port on an Arris Surfboard S33 Cable Modem support page:

                                            Standard Specification Compliant	DOCSIS 3.1

                                            Connected with a 10m Cat8 Cable.

                                            ifconfig -m ix1 reports:

		media 10Gbase-T

                                            From the transfer speeds it definitely seems to be connected at greater than 1Gb and seems to be 2.5Gb from what I can tell. Obviously it's not paused.

                                            The latest Intel Driver is 3.3.24

                                            The README still says:

                                            This driver supports the following media type options:

Media Type          Description
----------          -----------
autoselect          Enables auto-negotiation for speed and duplex.
10baseT/UTP         Sets speed to 10 Mbps. Use the ifconfig mediaopt
                    option to select full-duplex mode.
100baseTX           Sets speed to 100 Mbps. Use the ifconfig mediaopt
                    option to select full-duplex mode.
1000baseTX          Sets speed to 1000 Mbps. In this case, the driver
                    supports only full-duplex mode.
1000baseSX          Sets speed to 1000 Mbps. In this case, the driver
                    supports only full-duplex mode.

                                            Here's the dmesg output from boot:

                                            ...

                                            WAN is on ix1, LAN is on igb1, ix0, igb0, and re0 (motherboard) are not currently connected. Eventually ix0 will connected to a 10GBASE-T SFP+ transceiver on a 10G switch as soon as I get around to installing the switch with another 10G Cat8.

                                            So the hardware still seems happy to auto-negotiate to 2500Mbps, even though the FreeBSD ix driver can't report it. ¯_(ツ)_/¯ Annoying, but usable. Where do I sign the "Dear Intel" "metoo" petition? ;-)
