I didn‘t issue these commands but I did test my setup with a managed netgear switch to have only one ethernat-cable connected to TO’s WAN Port that serves both LAN and WAN (Coming from Modem) on diffrent ports (Similar to what @liquid tries to set up).
This setup worked, I tested it by pinging all relevant destinations. However I reverted this setup because it was for testing only.
EDIT: I think you mix up vlan known to TO‘s CPU and vlan on switch chip (See my answear to your other thread) (Switch chip not working?)
