The most important step to accomplishing quality of service (QoS) is planning. To receive expected results, you must review your network equipment and monitor network traffic.
This topic also includes a planning advisor. The QoS planning advisor leads you through the basic questions you need to ask yourself during the planning phase. In addition to the advisor, consider these subtopics before configuring QoS.
QoS is all about network performance. The main reason you are considering QoS is probably because you are already experiencing network congestion and packet loss. Before you carry out any policies, you might want to use the QoS monitor to verify your IP traffic's current performance levels. These results can help you determine where congestion is occurring.
