Can anyone help to see why the pre-emption is not working?
1. AP connected to the master MD,
2. the master MD failed, AP failed over to the backup MD.
3. AP stayed connecting with the backup MD and did not go to connect to the Master MD unless rebooting AP.
Thank you!
Here are config for two managed devices.
