High Rate of STP topology change

[Meksoh]

Hello,

I am seeing the error alert: High Rate of STP topology change. Nothing was changed in terms of STP configurations but we are having this error on all the switches on our network.

High rates of STP topology changes usually indicates an instability or changes in your L2 network.

It's very likely related ports coming up, going down or flapping.

Check the switch event logs to see what events are happening.

You can check your physical connections to ensure they are in good condition.  If you’re connecting a Meraki switch to a Cisco network, both using the Rapid Spanning Tree Protocol (RSTP), you might see this error. One solution suggested  is to configure your Cisco switch the MST.

Hi @Meksoh , this is normal behaviour.  These are your IP endpoints going to sleep and waking up as and when used.

We recently started a migration to Cisco Catalyst from Meraki MS environment and began noticing high rate of SPT changes. 

In short, our problem was that the endpoints attached to Meraki MS such as printers, APs, phones when bouncing would result in a Topology Change on that VLAN. Change the endpoint port config to Access port instead of TRUNK with native vlan solved our issues, since edge port up/down won't trigger a TC.

In hindsight, if this environment is permanent, MST would be the way to go.
