Yeah, but wouldn't you have to set that port up first? Isn't going to help you if you just plug an unknown PC into an unknown jack. PC wouldn't even connect, right?

You can identify a switch connection by using LLDP on most switches and if it's a Cisco CDP will give you info about the port connection. The Pockethernet does both. You can also find software for laptop that will do this but much easier with the Pockethernet.

how about "show arp" on the switch - you get a list of ports, the IP address associated with it, and the MAC address

don't think ARP would show physical ports. It just corresponds IP to MAC

Remember the original issue:
"a customer who's downsizing that wanted to disconnect phone and data connections in a vacated part of the building"
Active ports plugged into vacant locations and his standard Tone Generator and Inductive Amplifier isn't working for him.

"a customer who's downsizing that wanted to disconnect phone and data connections in a vacated part of the building"
Active ports plugged into vacant locations and his standard Tone Generator and Inductive Amplifier isn't working for him. What I would do is tag and disconnect all dark drops from a switch then put tone on a vacant jack(s) (if you have more than one toner that would really speed things up). Then find the drops back at the switch with your probe. If your toner/probe can't work with unterminated CAT5 you need a better one! The probes with the insulated tips are junk. What I've done also is to use my STM-8 cable mapper with several remotes plugged into several jacks. Just take the drops at the switch and connect them to the mapper one by one. When it shows a remote you found a jack. Easy peasy. -Hal

I think my way is easier than that. I plug cable into Pockethernet, open the app on my phone and connect to device, run test. This will give me POE info, all 4 pair + shield length and status, Link speed, switch info with switch ID and port # you're connected to and more if I wanted it. This saves me a lot of walking many times I don't even have to locate the switch.

I was suggesting ways to do it with equipment that he should already have. Certainly if he wanted to buy some new gear the Pockethernet sounds like a great addition.
