(Yes.. sometime it’s bridge, sometime its spantree and debug commands are “stp”… Nothing coherent !)

Root Guard

Link Aggregation

Creating a LAG does not create a logical interface (like on Cisco/Juniper/HP), the first physical interface of the LAG become the “Primary Port”, if 1/1 and 1/2 are on the same lag, even if you unplug 1/1, you could see it as root port on STP because 1/2 is still part of the LAG and is up (and is the primary port)
