The symptoms would be that the interface would "flap" every 10 or 20 minutes; it would go down an up without apparent cause. I can now quite-reliably report that it's not linked to VLANs; it also appears to show up *ANY* time there are multiple instances of an Ethernet interface up on the "ue" driver, irrespective of whether it's multiple instances on one interface (e.g. the VLAN example) OR multiple instances on multiple physical interfaces (e.g. ue0, ue1 on a plugged-in USB ethernet instance, etc.) I have _*41 days*_ of uptime at present on a single-instance device with ZERO flaps. But on a device with three instances, one with two physical interfaces in which one has a VLAN and base, the other just a base interface, it happens every few minutes. If I "down" the VLAN interface /it still happens./ Jun 13 09:04:53 IPGw kernel: ue0.3: link state changed to UP Jun 13 09:25:46 IPGw kernel: ue0: link state changed to DOWN Jun 13 09:25:46 IPGw kernel: ue0.3: link state changed to DOWN Jun 13 09:25:46 IPGw kernel: ue0: link state changed to UP Jun 13 09:25:46 IPGw kernel: ue0.3: link state changed to UP Jun 13 09:37:50 IPGw kernel: ue0: link state changed to DOWN Jun 13 09:37:50 IPGw kernel: ue0.3: link state changed to DOWN Jun 13 09:37:50 IPGw kernel: ue0: link state changed to UP Jun 13 09:37:50 IPGw kernel: ue0.3: link state changed to UP If there are logging entries that I can enable to try to find the cause of this it would be great -- this particular device is a RPI3 running -HEAD, but the issue traces back to at least 11.0 on the RPI2, where I saw it repeatedly close to a year ago, and there has apparently been no resolution. This looks PR-worthy but without some sort of trace on the REASON for the flap it's not so useful, thus the question as to whether I can dig up a logging option that will inform as to *why* the interface was marked down. It is NOT the switch port that the unit is plugged into OR the physical RPI3 hardware; I have swapped both the RPI3 board and switch port but the problem still exists and the other unit with one interface in service and NO flaps over 41 days of uptime is plugged into the same physical network switch.
