A couple of years ago, I got a report on my switches which told me which had the most errors, such as duplex and speed port mismatches, etc. It was concise and easy to quickly ascertain where issues were.
I don't know what program this was, as the engineer left the company without turning over these keys to kingdom.
I think this is a syslog server or an snmp server.
Looking to find a tool (hopefully free). Hoping this runs on a windows box, although with good documentation, I could run it on a linux distro. (linux nOOb)
Thank you for your suggestions.
