This thing is nice...https://www.pockethernet.com/
It's saved me many footsteps and lots of time. Just did a service desk move that had 8 data cables. I identified the port each device was plugged into, run new cables, connected the patch cables and was done in 2 3/4 hours. The store contractor said he never see anyone do it so quick and organized. It gives nice report at the end that can be saved as a pdf, emailed or uploaded.
Thank you newtecky for finding this for me.
