Hi elderone
Welcome to NETGEAR community.
Can you kindly provide us the detailed GS728TXS/GS752TX/M7100-24X topology when you saw the same issue with Unifi AC-Pro access points?
Here's network layout:
RSTP keeps link open between GS728TXS and GSM7248v2.
Tried also connecting AP-s to GS728TXS, at the same time I did block MAC 01:80:c2:00:00:1c on GS728TXS uplink ports. "My PC" did get access to Unifi AP-s fine, but most of the time Unifi controller didn't get data from AP-s - controller showed that AP-s missing heartbeats, disconnected and occasionally connected.
