4.2.49 QoS->Queue Config->Queue Mapping
The priority tag of each packet is divided into four queues on each output port. The default setup is each queue taking two priorities sequentially. The Administrator can configure the traffic class as needed. Enabled or disabled Queue Mapping within the QoS Status field.
To provide quality of service, each packet carries a priority using a different approach. The IP packet has a ToS in the header. The IP packet is three bits in length and uses a priority from 0 to 7. The larger number, the higher priority. To ensure high priority packets are delivered first, four priority queues per output port are established. The priority tag of each packet is divided into four queues on each output port evenly. The default setup is each queue taking two priorities sequentially.
