Tracing out Live Network Cables
This clever trick helps you identify un-marked network outlets. A Toner and Tone-probel will not work when a network jack is connected to a live switch port in the server room (switch room). By using a simple batch file running on a laptop, you can create a beaconing effect using the swithes link lights.
If you have ever tried to identify an unknown network location by using a toner and probe, you may have experienced the problem of not being able to trace the tone back in the server room (or, whatever you call the room where you keep the patch panels and switches). This is because if the network port is plugged into an active Network Switch port, the tonner stops working. This makes it pretty much impossible to use the toner and probe to identify your network cable.
The solution outlined in the video uses a simple DOS batch file running on a laptop to turn the network adapter on/off in a rhthymic fashion. This causes the link on light on the switch (in the server room) to turn on/off in a matching cadence. While the laptop is plugged into your Un-identified network outlet and running the batch file, you need to be in the server room looking at the link lights on the switches.
This may take a few minutes, but it's going to work way better than the tonner/probe approach.
Now, if you're really fancy and you have access to the Cisco command prompt (assuming you have manageable switches), then you could simply plug in any network device and do a search for the mac address. If you know how to do that, then knock yourself out. This video is just proposing a simple solution for those trying to solve a problem. Often times, as network repair personel, even though we do know how to search for the mac address in the switch, we're usually not given that level of access.
You can get a sample batch file from the Network Advisor website in the tools section. Warning though, windows security sees batch files as potentially harmful files, so downloading, editing, saving may be tricky. I suggests turning off the WINDOWS ACCESS CONTROLS while working with the batch file.
The following batch file is known to work with Windows 7 and Windows 10. I tried it on XP and it said the parameters were invalid.
The batch file looks like this:
-------------------------------------------------------------
:begin
netsh interface set interface "ethernet 2" admin=disable
netsh interface set interface "ethernet 2" admin=enable
PING 1.1.1.1
Goto Begin
------------------------------------------------------------------
HELLO!!!! READ THIS ::::: You will need to edit the batch file and replace the network interface name in the "Quotes" to match the network name of the one on your computer.
And, in case you're wondering, the PING 1.1.1.1 is just in there to provide a delay. Yes, you can use other methods like TIMEOUT and SLEEP.
If you're having trouble with the batch file, try doing some internet searches, there is a wealth of information out there.
