THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY.

A new Flyspray task has been opened.  Details are below. 

User who did this - Nico Schottelius (telmich) 

Attached to Project - OpenWrt/LEDE Project
Summary - Selecting lan port in Luci from off -> untagged breaks networking
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
 - Device problem occurs on

ZBT WG3526

 - Software versions of OpenWrt/LEDE release, packages, etc.

19.07.05

 - Steps to reproduce
   
Overall:

If I select the LAN1 on a wg3526 from off to untagged, luci wants to make 2 changes, one of which breaks the configuration:


    it renames the network.lan.ifname from eth0.1 to eth0

    it changes the switch port configuration (that one was expected)

Removing network.lan.ifname=eth0.1 and replacing it by network.lan.ifname=eth0 breaks networking. Rollback properly works.

After some other changes / manually fixing it, I have the following board.json:
