RSTP on Ubiqiti, how to set it up?

Question

Cisco

Hello comrades.
I still can’t figure out how to force ubiquity so that he does not consider himself a root switch?
There are 2 switches, the Tsisk Catalyst 3750, it is the core of the network and, accordingly, the root switch in the STP topology, the Ubiqiti EdgeSwitch 8-Port 150W access switch for access points is plugged into it. I can't figure out what's wrong? Why do tsiska and ubiquity consider themselves root?. Below are the configs of the hardware.
I need help you.

Answer 1

I see that RSTP just doesn't work between two devices. They live in different instances, if Cisco received a BPDU from Ubiquity, then we would see a non-edge port type. The reason is that rapid-pvst is not the same as rstp.
Cisco's "classic" RSTP lives in an untagged wealan, so the solution is either native vlan 100 on Cisco's ports or adding the first wealan to Ubiquity's ports. It is necessary to fulfill the rule RSTP = untagged traffic.
I didn't find it for edgeswitch, but for UniFi there is this document https://help.ubnt.com/hc/en-us/articles/3600068367... and I quote:
