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.
