Constant link status changing with VLAN configuration

[matt.will]

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?

[matt.will]

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

[matt.will]

Any thoughts? Considering a downgrade to 2.2

[Derelict]

It's not something systemic with 2.3.

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

[matt.will]

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

[matt.will]

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.
