      Switches not using active mode?

      I assume they are correctly stacked and support cross chassis LACP?

      Try setting: sysctl net.link.lagg.lacp.debug=1 that will give you a lead more debugging info in the system log.

        Good day Steve,
        appreciate your support, yes the switches are stacked and correctly stacked,
        our Synology is using the LACP and working fine,

          Ok, then enable lacp debugging and see what gets logged.

              In pfSense run this command to set it temporarily:

              sysctl net.link.lagg.lacp.debug=1

              Or add it in Sys > Adv > System Tunables to set it more permanently.

                sysctl net.link.lagg.lacp.debug=0

                  Yes exactly.

                  Or just reboot since that sysctl is not set in the config.

                    Steve I appreciate it, ill give it a try tomorrow and report back.
                    I hope to see the cause on the debug.

                      Good evening Steve,
                      I have enabled the debug, when I connect the cables nothings really shows on the log of console when I was ssh to the box.
                      am I supposed to do anything to see those logs?

                        You should see a bunch of entries in the main system log once you enable that.
                        For example:

                        Nov 23 20:06:01 	kernel 		ixl1: lacpdu transmit
Nov 23 20:06:01 	kernel 		actor=(8000,00-E0-ED-86-A6-8C,02B2,8000,0002)
Nov 23 20:06:01 	kernel 		actor.state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>
Nov 23 20:06:01 	kernel 		partner=(8000,0C-80-63-69-C2-DE,0ADC,8000,001A)
Nov 23 20:06:01 	kernel 		partner.state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>
Nov 23 20:06:01 	kernel 		maxdelay=0
Nov 23 20:06:01 	kernel 		ixl0: lacpdu transmit
Nov 23 20:06:01 	kernel 		actor=(8000,00-E0-ED-86-A6-8C,02B2,8000,0001)
Nov 23 20:06:01 	kernel 		actor.state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>
Nov 23 20:06:01 	kernel 		partner=(8000,0C-80-63-69-C2-DE,0ADC,8000,0019)
Nov 23 20:06:01 	kernel 		partner.state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>
Nov 23 20:06:01 	kernel 		maxdelay=0

                        The problem with that setting is that it fills the system log with data usually. Especially if there's a problem.

                        For reference that is an XG-7100 connected with the X710 expansion card to a Brocade ICX6450. And working correctly.

                          Sorry Steve,
                          I've found it had to use google ssh to show the logs I don't know why putty didn't wanna shows the logs.

                            That the console output rather than the system log? It looks like it.

                            You should see more that that at least when it initially comes up. Check the system log in the webgui or use:
                            clog /var/log/system.log at the CLI.

                                OK, the flowd stuff is not relevant. You need to looks at the lacpdu output which should look at least vaguely like my output above.
                                It's all from the 'kernel' process so you can filter by that to lose all the netflow entries.

                                The fact the switch shows the ports as blocked is not good...

                                  if the switch shows they are blocked mostly is the switch or the pfsense?

                                    Hi Steve.
                                    I have this log now after I connect the cables.

                                    and the switch still showing the ports are blocked.

                                      The switch probably blocked the ports for the same reason pfSense stopped the interfaces.
                                      They were flapping for some reason and leaving them running like that could cause far more problems. We have to try to find out why.

                                      I would disconnect and reconnect the ports and see what is logged.

                                      Try connecting only one port and see if that prevents the flapping.

                                      Steve

                                        After I connected the cables one by one it still shows the flapping, but the error comes up.

                                          Maybe check debugging is still enabled. You should see some log entries from lacp there.

                                          Edit: Sorry missed a whole post of yours somehow. Ok I see logs showinh both ends timing out.

                                          And it still showed flapping with only one NIC connected? em2 there in the logs?

                                          What do you see if you run: ifconfig -vv lagg0?

                                          Steve

                                            Looking at the switch there it looks like you might have short timeouts set?
