Good Afternoon,
First time posting, I apologize if I don't know the proper ettiquite of what information to post that will help you help me.
I've got a site with a Cisco 3750 as the core connecting our virtual infrastrucure (SANs and Virtual Hosts) as well as our Access Layer switches together. After looking at the logs in response to an issue I had over the weekend, I have found that we have several ports chaning up/down for no obvious reason (by obvious I am reffering to the network cable being unplugged/machines going down).
This has been an issue at two geologically seperate campuses (Buffalo, NY and Richmond, Virginia)
Any thoughts on what would cause this? All of the ports configured are set as ACCESS ports. See below for logs and interface configs:
