Lots of times we are troubleshooting cisco switches connectivity and performance. Under the stress of the moment, we forget some essential IOS commands that can save us time and effort.
The most common IOS command to give us a clear picture of the switch interface is the show interface or show interface description command. It gives us a lot of information about the interface status, the working configuration, protocols, errors, collisions, etc.
