I've found the VLAN test feature to be most valuable. That's because not many devices do VLAN tests. Normally, I have to send a center technician to check a line and see if it's alive. If it's working, then I have to send a network technician out to log into a switch and see which port it's on and on which VLAN that port is. That's two persons and two separate visits. This device does all of this in a matter of seconds, and that has saved me a lot of time, troubleshooting, and resources. Its ease of use is very impressive. LinkRunner allows me to have my technicians run tests that are normally too complex and require a network specialist. AutoTest works with just one click. AutoTest does a lot of testing that would normally require a network specialist to log in to a switch and check out VLAN based on a port. My technicians don't have to log in to the switch anymore. They can just do AutoTest and information is provided online. So, I no longer have to send a specialist. I can have my technician run these very complex tests. It saves me on resources, time, and site visits. When it comes to troubleshooting, based on my experience, it has given very useful and very helpful information, especially for my field technicians. It has reduced my visits and the amount of presence because it gives a very comprehensive report on your network tests. It tests multiple variables and multiple parameters and gives a very informative report that makes it easy to pinpoint what is the root cause. There are many tools in this one solution. It's basically a bunch of toolkits or tool sets in one device, which makes it very powerful testing equipment.
