      I don't know that a pfSense forum is going to be the best place to get help with your edgeswitch.

      All 4 LAN ports on the SG-3100 are expecting to be connected to an untagged switch port by default.

      What port are you connecting to?

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        I've tried LAN ports 2 and 3. Both don't connect to the switch

          Are you running pfSense 2.4.3 on the SG-3100? Define "Don't connect" - as in no carrier? Is the edgeswitch port hard-set to something other than auto-negotiate?

          Might be seeing some weird auto-mdx issue. Try a good, 8-conductor crossover cable to see.

            • Yes I'm running pfSense 2.4.3 on the SG-3100

            • What I mean by "don't connect" is that none of the green led lights on RJ45 jack on the SG-3100 light up. The switch does not work when plugged into the SG-3100 router.

            • The port is configured on auto-negotiate.

            • I've tried a good 8-conductor crossover cable.

            When I try the exact same setup and exact same Ethernet cables with and EdgerouterX router instead of the Netgate SG-3100, the EdgeSwitch works fine. As soon as I replace the EdgerouterX with the SG-3100, the EdgeSwitch no longer works as a switch. Nothing plugged into the switch gets connected the WAN.

              are you able to ssh into the switch and see if there are any logs/console output wen plugging/unplugging?

              Slow code? Sounds like a good reason to buy more hardware!

                Must be some sort of auto-neg problem with that switch. Works fine on everything I have tried. But I don't have one of those. Nobody has reported the same as you are seeing as far as I know.

                  Bottom line: Dark LED=no Layer 2.  No layer 2 the rest doesn't matter. Are the boxes next to each other and separated by a single patch cable or are there are wall cabling in between?  Very disconcerting, more layer-2 issues in the forum than I had expected gone by the way of polio.

                  If u use multiple-LAN, something tells me to tell you to plug one LAN port only on the 3100 and see if lights.

                  The EdgeSwitch is not a POE-fed device is it? because that would be embarrassing-to-the-max.

                    Connect the a known-good, 8-conductor patch cable between OPT1 and one of the switch ports (not two of the switch ports as that will create a loop.)

                    Does link come up on both?

                      Arghh. So it did end up being the patch cable. The RJ45 jack was not seating properly in the SG-3100, but somehow had no problems in the EdgerouterX. Thank you for taking the time to help fix this obvious yet un-obvious problem.

                        Sammy to user:  Plug in the RJ45 cable, it MUST go in with a SOLID POSITIVE CLICK and no mushiness.
