@Leonid_Kristin
You need to set LAN's device to br-lan.10

@jow
We need a tagged<->untagged CPU port migration like how it was done in swconfig.

Hello. Can you explain a little bit more I didn't get it.

Thanks a lot it works now!!!!

Not sure how a suitable algorithm for that would work. Migrate any "br-lan" users to "br-lan.X" upon declaring the first VLAN? What if the VLAN is deleted again? Or the ID changed? What if the "Local" flag is disabled? I am afraid that it'll be a lot more complex than swconfig.

How about similar solution like you did with swconfig to prevent softbricks: define always a vlan for lan already in the device default config definition.

I have wondered if something similar is needed for DSA devices.
