We have been experiencing an issue where an 8-Port POE switch keeps rebooting about once every half hour/hour. On the Meraki dashboard it is reporting DNS is misconfigured. I have used the "Google machine" and also Meraki's knowledgebase with little to no assistance. Though I would through this here and see if anybody has any suggestions.
Does the DNS misconfigure message only occur right at boot? As in, does it go away after a few minutes? I've noticed this on a variety of Meraki devices that they will initially complain about DNS, then "figure it out" and go 5x5.
For the reboots, anything interesting in the event log right before it reboots? Have you seen it in person? My initial guess is a PoE device/cable that is bad and causing a surge (it happens) or a bad switch (also happens).
