  It’s a moment every administrator dreads: Your network is crying for help, and you don’t know why. Wouldn’t it be great if, right in your hand, you had a tool that could diagnose the problem? We test four handheld analyzers to see just how they can make your job easier.

  by James Carrion

  July 2003 — When the network is down, screaming users and an irate boss turn some network administrators into troubleshooting machines. Others simply rely on the fates, with ad-hoc troubleshooting techniques or default diagnostic utilities. Worse yet, some put their faith in plain, dumb lUCk (i.e., reboot everything). Sure, the network eventually comes back up, but the extended downtime has your users and boss still fuming and, perhaps, even plotting your demise. What you really need are good troubleshooting tools that can quickly pinpoint the problem—and make everyone’s future a bit brighter.

  Handheld network analyzers started out as basic, physical-layer, network-diagnostic tools and have evolved continuously. They now perform multifunction diagnostics at all layers of the OSI model, helping administrators troubleshoot myriad network problems. Ten years ago, I watched a co-worker use a multimeter to detect shorts in cables and connectors while lugging around a heavy oscilloscope to perform basic diagnostics. Today’s network analyzers—which are small, self-contained devices—can perform the same tests and provide results in a user-friendly graphical format.
