I disabled RSTP on the ports on each end and now my backup traffic goes through the shortest path, thanks for the advice. If I use "MAC Allow List" on each end to limit communication to only the two switches, can it secure the disabling of RSTP? For the rest of our deployments we will use C9300-48P. With IOS, the "no switchport" command is possible so the hardware supports it. I hope this will be possible with the same hardware in the Meraki dashboard, I will ask support. Thanks again for your help.
