Removing LAGG. What happens to VLANs?

valepe69

@stephenw10 I have my LAN interface on a LAGG with 2 ports.
I wish remove the LAGG leaving only one nic for my LAN.

I read the topic but I have a doubt about VLANs. What happens to them removing the LAGG?

Thanks

The VLANs are on the lagg?

They would become invalid if you remove the lagg. You would need to re-create the VLANs on the single interface and re-assign them before removing the lagg entirely to maintain connectivity.

If you have a lot of VLANs a change like that can often be more easily accomplished by editing a backup config directly and restoring it. Of course that carries some risk!

Not sure how the business logic is written, but I'd advocate for not letting a user remove a lagg before sub interfaces are removed or moved to another interface.

BTW, I'd say that would be a great feature, moving VLAN sub interfaces from one interface to another via GUI.

That's already the case. If you try you see:

The following input errors were detected:

    This LAGG interface cannot be deleted because it is still being used.
