how to find what's connected to an interface one hop away
I created a network map in solarwinds and it's showing me some links that should not be connected together. How can i confirm what's plugged into a port on my switch one hop away without crawling through the walls or disconnecting the wire? I know there's a show mac command to show the mac adresses but it shows everything out that port. I need to confirm without a doubt what's plugged into a port on my switch. thanks.
