Lan ports suddenly stopped working

Hi folks,

The LAN ports on my turris 1.0 router stopped working a couple of days ago. I did a factory reset, and had to perform an upgrade (quite tricky using the serial console),with migration to btrfs, and then got through the latest medkit and factory reset to HBS version 7.0.2. Wifi and Wan are working, but the lan ports are still down. This is not a hardware bug, during the upgrade the ports worked, at least the one I had the pc connected through then. I know similar problems have been addressed here, but I still haven’t found a solution.

Update:

Further investigation leads to the conclusion that the cause is a misconfiguration in the /etc/config/network file. What would a sample configuration in tos 7 for turris 1.0 where the lan ports are functional look like?

Solved. Accidentaly connected external switch cause the problem. Mea culpa. Mea culpa. Mea maxima culpa.
