Last fall I had the pleasure of winning a Fluke Networks LinkSprinter 200 network tester on Twitter. Since then it has become my go to tool.
In my environment, I have a lot of links that are poorly labeled and that are on VLANs without DHCP. This means having to tone out or trace cables when the desktop team or server team comes to me wanting something moved to another VLAN. That's where the LinkSprinter has been a life saver. Now when they come to my desk, I just hand them the LinkSprinter and tell them to press the power button once they hook up the cable and wait until it either gives them a red icon or a green solid cloud.
When they bring it back, I plug it into my spare port and within a minute I have their port reports in my e-mail. From those reports I can easily see the CDP information and know exactly what port on what switch needs changing. The tool also tells me about POE, speed, duplex, dhcp and latency to a cloud target. In the field of course, I also have made use of the wireless feature to see the results instantly on my iPhone.
I used to carry my OneTouch AT with me a lot more, but I have found the LinkSprinter to replace the OneTouch AT for many smaller daily jobs. Both its size and its price make it a perfect tool for every engineer and technician. My organization is currently reviewing the idea of issuing our desktop support team with LinkSprinters to help decrease problem resolution time.
If you haven't bought one, I highly suggest you head over to Amazon and get yours today.
