We were having some spanning tree issues, covered in this thread: Poor Dell Switch Health, and as I was doing some diagnosing I noticed that BPDU protection was off on our core switch. As soon as I enabled the protection, it seems to take care of the issue with spanning tree, but I am unable to reach a couple of switches after that. Any idea what the reasoning would be behind that? Is there some conflict going on? Thanks for any help in advance.
