Interface errors can be the first signs of deeper problems, and in this episode, we cover the most common indicators that a link is failing. You’ll learn how to recognize and interpret error messages such as input/output drops, late collisions, CRC errors, and alignment problems. These clues can point to physical issues like bad cabling, interference, or even failing hardware components like transceivers or ports.

We also examine how environmental conditions—such as temperature, humidity, and airflow—can impact network reliability. You’ll learn about SNMP-based environmental sensors, thermal monitoring, and proactive steps to prevent equipment failure due to environmental stress. This episode teaches you to think beyond configuration and into the physical reality where your devices live.
