I am having the same issue. College campus, each building is basically a network. I am only seeing the issue on stacked switches and the issue only shows up on the switches in the stack that don't have the uplink. For instance, I have 4 switches in a stack, switch 1 has the fiber uplink and 2, 3 and 4 are using switch 1's uplink. 2, 3, and 4 have a DNS Misconfig error and won't forward packets. Switch 1 isn't reporting the error. Having this issue across 8 buildings/networks. At my science center, I have 46 switches but only two stacks, a stack of 2 switches and a stack of 6 switches. Switch 1 in each stack has the uplink and is fine but the others are error'd out. Also, the other 38 switches have no errors, every switch in the building goes back to a Cisco 9500. Did you find a solution to your issue?
