### ⭐⭐⭐⭐⭐ IMPORTANT TOOL for every network engineer.
*by J***) on January 17, 2024*

It's basic, but it's necessary, and it works VERY well. Can't tell what switchport a wall port goes to? Throw on loopback detection on every port, plug this thing in, BOOM! Port identified! WAY easier than toning out cables!
