Understanding network switch functions
With network engineering comes great responsibility and critical thinking. Not only do you have to perform device configurations, but a lot of your time may go into problem-solving and performing extensive troubleshooting techniques. On a network, at times you may encounter users reporting they are experiencing poor network performance such as high latency. Such issues may be caused by interface misconfigurations or a physical issue.
As you have learned, switches play a vital role in almost all networks of any size; from the small-office home office (SOHO) to a large enterprise network with hundreds of connected devices, they are the main network intermediary devices that physically connect everything together. In this section, we are going to discuss various network-related issues that can affect the performance of a network and how to resolve them.
In an ideal environment, we should connect only one end device to a single physical interface...
