We we have 2 L3's in a stack that act as root for the STP. Then 4 L2 switches below that. All of the 4 L2 switches are warning me of a high rate of STP topology changes. 3 of those L2 switches don't have anything in event log from the 15th up till now. One of them has logs up to this AM around 830. The configurations on all the equipment has not changed in a long time, since before I came to this company. Since I started here we have been working from home, I started on what this company calls, covid day, the day the ceo sent everyone to work from home. Now everyone is hybrid, so a few days a week in the office (~2-3 days at most)
We did have a big power outage last week for ~18hrs (nasty nasty storms) and the battery backups didnt last long enough to keep everything online. I came in over the weekend to double check everything and get everything back online and my VM's. After I got the VM's back online (which host our dns/dhcp) I was able to connect but dns was having issues still and after all my fixing to get that running, last thing I had to do to get it to work, for some odd reason, was to reboot my network appliances. So I started at the bottom with the AP's and rebooted those and boom my dns and everything started working. LAN it was not so I rebooted the switches one by one and then it all started working again. Later that night is when I noticed the high rate of STP topology changes messages on all my L2's. Ive done packet captures and gone through them in WireShark and I am not sure if I am understanding them correctly but I am not seeing much info.
FYI - I am still fairly new to the meraki systems and I dont know alot as to how the STP topology works on these but I know vague basics.
So any help would be greatly appreciated ladies and gents.
