      How does it work ?
      Nothing in the documentation about it, interfaces doesn't appear in the menu lagg and the messages in this forum and everywhere else mention a menu that doesnt exist anymore: https://forum.netgate.com/topic/131207/lagg-on-switched-ports-on-sg-3100 (previous version of Pfsense I guess)
      The command line command in the above topic doesn't seem to work anymore.

          Hi.

          I want to use the 1st and 2nd port of the switch as a single lagg interface.
          For the moment I use the 2nd port as a ''backup'' of the 1st one (simply by plugging them on the same lan, with STP capable switches).
          Is there a way to do real LAGG? (the screenshot in the mentioned thread confuses me because I don't have a LAGGs menu in the Interface-->Switch section (pfSense 2.4.4)) Or is it the only way to have a backup link on my lan side ?

            What you do is set two ports to the same VLAN configuration then, on the Interfaces > Switches, Ports tab you can click on the LAGG on each port and set an unused ID, Such as 1 on the LAGG ports.

            Note that this is a Loadbalance type lagg, not LACP, etc.

              ok, thanks for your answer.
              It's what I tried, but when I do that my pings stop and never recover. Is it a normal behavior with a loadbalance lagg ? (I've only used LACP on xg-7100 for the moment, with two real physical iface)?
              Does this have something to do with the sg-3100 having only one mac address for the 4 switched ports ?

                A layer 2 lagg should not care about MAC addresses.

                You have to be sure you're connecting it to a switch in a compatible configuration.

                  Is it possible to do a LACP LAGG on a SG-3100? I have seen conflicting information on the pfSense forums.

                    Using WAN + OPT1, Yes, using pfSense LAGG.

                    On the switch ports, No.

                      Greetings,

                      Thank you for the clarification.

                      I have read through lots of documentation and still when I try to create a LAGG I don't have any parents interfaces to choose from. I have multiple VLANs created, dot1q enabled, etc. and simply can't get interfaces to show up in the parent interface section when trying to create a LAGG.

                      Can anyone assist?

                      Also, is the limitation of not being able to do LACP on the SG-3100 switch ports something that Netgate could add in the future with a software update?

                      Thank you,

                      M

                        You can only create a pfSense lagg on unassigned interfaces, so if mvneta0 and mvneta2 are assigned to interfaces under Interfaces > Assignments then those will have to be deleted first or at least moved to something else so you can retain all of the configuration. For instance you could create a couple of throwaway VLANs on mvneta1, temporarily assign WAN and OPT1 to those, thus freeing up mvneta[02] to make the lagg, then add VLANs to the lagg, etc and reassign WAN and OPT1 to the lagg interface/VLANs. Then delete the throwaway VLANs from mvneta1.

                          Make sure you have working console access, in case you accidentally remove all network access to the WebUI.
