As an IT administrator, I often need to know where that port I am troubleshooting runs back to. In a perfect world, they would all be labeled. Unfortunately, a lot of mine are not. I rely on Netool.io to help me track down cables to the switch port. You can also find a lot more information as well.

• VLAN
• Switch IP
• Switch Hostname
• DHCP
• LAN IP
• LAN Subnet
• LAN Gateway
• and much more

It’s small enough to fit in your pocket. I highly recommend it. You can purchase it on the Netool.io website for $199.
