Скачать или смотреть Connecting 1 Router, 2 Switch and 2 PC - CCNA practice lab

In the past video, I mention that I didn't properly understand what is the color indicator in the connection means.

The color indicator represent the status of the connection of the devices.


Green indicator means that the connection is active so they can communicate with each other.
Orange indicator means that it has connection but there is some issues like packet loss, latency or network problems.
Red means the connection is down so they are not communicating with each other.

In this video I connect the router and the switch and so I understand the color indication and what they mean.


if there is something wrong with my explanation, feel free to criticize it your feedback helps me understand/improve my craft thank you so much :D
