      23.05.1-RELEASE.

      After rebooting, or power cycling, after about ~30sec, the LAN interface starts bouncing endlessly.

      I got it to stop after nuking the interface configuration previously, and another time by running /etc/linkup stop em1 followed by start of the same.

      Don't see any obvious precursor in the logs, just suddenly this... endless down/up cycle:

      I plugged the LAN interface into a temporary dumb switch, with nothing else plugged in, to rule out my downstream switch being involved, and same cycle.

      @jimp this sounds like what you mentioned here

        After that log does it just show link down again? Can we see logs showing at least two cycles?

          @stephenw10 after intervention (linkup action I mentioned previously) the interface is up, and functional, otherwise sans intervention that log simply continues, seemingly endlessly. Steps to repeat are simply to reboot the device.

          As an aside, L2 or even L1 reset of any kind during the "event" (i.e., switch interface disable, cable pull) causes the interface to stay down, flapping ends. When switch connection is restored, the cycle continues (or perhaps starts anew?)

          I almost went down an exhaustive switch-side path, until plugging pfSense LAN into a dumb switch (no other connections, no STP, no nothing) produced the same results.

          I'll attempt to gather logs just as soon as my schedule permits. Thanks for your time.

            @stephenw10 correcting my previous post(s), an interface shutdown via ifconfig seemed to be the "kick".

            Recent logs:

              Anecdotally, and without much deep diving, I'm starting to suspect this is happening when the interfaces are put into promiscuous mode c/o Suricata (6.0.13).

              I disabled Suricata on a whim, rebooted, and haven't seen the problem yet.

                Are you able to test disabling the em1.4 (opt1) such that only LAN looses link?

                It appears it could be the fact that both interfaces are restarted that causes a problem. Though I have interfaces with many VLANs that don't do that.

                  @stephenw10 Sorry for the late reply. I removed the VLAN sub-interface from em1, and put the VLAN into pfSense (access switch-side) on em2. Things flapped briefly after turning Suricate on (individually, on each phy). tl;dr, looks like problem occurs w/sub-interface in play.

                    Do you have Suricata running in in-line mode on either em or the VLANs on it? That bounces the interface a lot more by inserting netmap.

                        Hmm, there must be something specific to your config applying to those interfaces triggering the race condition there...

                          @stephenw10 Aye, not exactly a burning community issue, and given this is home easy enough to do what I've done.

                          If this warrants effort on your side in the future, I'm happy to help further.
