      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

      Hi Steve
      yes each NIC I connect em0 or em3 it shows the flagging error.
      what do you mean with time out of set?

        My switch is set for Long LACP timeouts (the TIO flag) and yours it set short.

        Try changing that.

          Are you using a broadcom switch?
          i have changed the timeouts to long

          device(config)# lag blue dynamic

          but it stills shows blocked

            I'm using a Brocade ICX6450 there. It's a value you can set for each lag group:

            SSH@ICX6450-24P Switch(config-lag-lacp1)#lacp-timeout 
              long    Long timeout mode
              short   Short timeout mode

              Thank you Steve, i set it to long.
              see above
              appreciate your support

                You might have to redeploy it. The ports still show S in the Tio field.

                That's not something I've ever tried on this switch.

                  do you mean to remove the ethernets from the lag or delete the lag completed?
                  i am getting this error

                  Error: LAG WAN is deployed, please undeploy it first.

                    It's been a while since I had to mess with anything on this switch but I believe, like that error implies, you cannot make changes to the lag while it's deployed. You'll have to 'undeploy' it to switch to long mode timeouts.

                    You could also try changing the pfSense LACP timeout mode to fast (short) to match which might be easier. In 2.5 that's a GUI setting, I'm not sure I've ever set that in 2.4.5....

                      Though I note it did not cause the lagg to break with pfSense set as short and the switch as long...

                        do you mean i have to do it also on the pfsensen side too ?

                          It would be better to change that on the switch if you can but, as a test, you can set fast(short) mode in pfSense and that should also match each end.

                            Thank you Steve, ive done hte fast timeout on the pfsense unfortunately it still blocking the ports

                            on the switch too

                            === LAG "wan" ID 5 (dynamic Not Deployed) ===
                            LAG Configuration:

                               Port Count:    0
                               Primary Port:  none

                            both switches are stacked maybe forgot to mention, maybe its relevant .

                              Ah, OK. Yes it could well be, have you configured it for cross-chassis lag?

                              I have no experience of doing that with Brocade but I imagine it has to be configured for it.

                                Also check the switch logs. There is likely a reason those ports show as blocked and it should be shown there.

                                  i cannot seems to find the cause yet.
                                  we are still investigating i am affraid the switch and pfsense are not a good friends.
                                  i will try to use a different switch maybe unifi switch L:ayer 3 switch

                                    Are you able to test a lagg to a single switch rather than cross-chassis?

                                    Or even just connect the ports individually outside of a lagg to be sure they come up as not blocked?

                                      Are you able to test a lagg to a single switch rather than cross-chassis?

                                      Or even just connect the ports individually outside of a lagg to be sure they come up as not blocked?

                                        It seems like a loop that the switch is blocking then.

                                        I would expect to see something in the switch logs.

                                          i've been kicking my head down to find the log of the switch.
                                          cannot seems how to see them.
                                          what are the commands for brodcad switches to see the logs?

                                            On the ICX6450 I have it's show logging at least to get basic logs. I've never tried to get more.
