      So, I have five VLANs configured on a single igb parent interface. None of the VLANs are activated, yet I'm still seeing constant log entries that elude to link status going up/down. I never see any connectivity symptoms, so is this just cosmetic?

        No. Not normal.

        VLAN 190 on igb2 is functioning normally? Link is not actually flapping?

          Clean as a whistle. Sometimes I will see all five go into rotation like that. however, from the time stamps, the interfaces are only down for a few seconds. I could be seeing latency and just not know it

            Any thoughts? Considering a downgrade to 2.2

              It's not something systemic with 2.3.

              What do you mean none of the VLANs are "activated?"

                The VLAN interfaces aren't enabled. All of them are on igb2, but not enabled while I troubleshoot. The link state changes happen about time a day, all within a few seconds (logs above confirm).

                For reference, hardware is a Netgate 2440

                  Confirmed today; 17 hours after unassigned VLAN interfaces, the up/down link status messages have stopped. Seems to be somewhere in hardware or VLAN software. I am going to try to move them over to a different NIC, but not hopeful that it will have a different outcome.
