Hello, I always get "high rate of STP topology change" errors while updating MS switches in our networks. Most switches are uplinked with a aggregat to the distri switch. I there any idea to prevent this issue to avoid network errors on network parts which are not getting updated (staggered upgrade)?
Maybe the aggregat is not established while the switch is booting and going online?
Any good ideas?
@redsector : Did you set root priority for the switch, I mean spanning tree priority on your root to be lower than the rest of your switches and BPDU Guard ?

Yes, shure. The core is the boss. I mean best priority. It´s an Cisco Cat 6800, (root bridge around 8196) , all Meraki switches are Meraki standard (32768).
Hi @redsector , is your Cisco core running MSTP?
Take a read through the below which will help you tweak your config:

@redsector is it actually causing a problem? I see this often when updating switches but there is no user issue and the error soon clears.
Unless it is causing some other issue I wouldn't worry about this.
The error is probably correct and being caused by lots of Meraki switches rebooting due to the upgrade.
