Can I ask if any investigation has been done on this or whether anyone else has been able to replicate it? This will bite me after upgrading to 2.4.3-p1 which is planned shortly for a production environment. I note the assignee hasn't logged in for 6 weeks and I can't find any reports of this on the forums or elsewhere.

The reporter states "This also seems to affect HA configuration sync, the syncing itself kills the standby server's VLAN interfaces." Would this occur only when making LAGG/interfaces changes, or when making any config change, unrelated to interfaces at all?

I can't reproduce this, tested on 2.4.3 and 2.4.4.

Steps:

1 - Create LAGG;
2 - Add VLANs to LAGG;
3 - Edit LAGG.

VLANs are still there, parent interface is (correctly) set.

Is there something else that I'm missing or that I should test ?

Following the same steps as Luiz, I am also unable to recreate the issue on 2.4.4.a.20180817.2020.

I can't replicate also - created 3 vlan's on a top of Lagg, assigned vlan's and Lagg interfaces, enabled, assigned IP on all of them. Then changed MTU to 9000 on Lagg. Vlan's didn't loose its parent interface.

I am able to reproduce the issue on VM with latest dev factory

VLANs have not parent after changing MTU to 9000 on LAGG

Changing MTU on VLAN interface affects nothing, MTU is still the same.

I tested this in 2.4.4r and was unable to replicate the issue.

I created and assigned a 3 interface LAGG and added VLANs on that using igb NICs. I edited the lagg to remove an interface and also edited the assigned lagg interface to change the MTU.
The VLANs retained their parent in each case.
