When we visit our local doctor, sometimes we don’t always agree with what they have to say. Sure, we didn’t go to medical school and we don’t have a fancy degree on our wall. But heck, it’s our body and once in a while we know something just isn’t right. So what do we do? We get a second opinion. The same concept is important in almost any part of life – even network management. Sometimes something just doesn’t seem right, and we need to get a second opinion before we blindly trust what our hardware and software is telling us.
For years, Plixer (yes, even in our Somix days) has been using an excellent free tool called GetIf for walking MIBs and verifying SNMP information. It allows support technicians and users to verify device settings and configurations. It’s important to have these small, but incredibly useful, tools on hand. Whenever something doesn’t go as planned during setup, the first question to ask is always, “Is it the software or is it the hardware?” When helping customers and evaluators setup Denika Performance Trender to monitor their SNMP enabled devices, GetIf has always been invaluable in helping answer that question.
