QoS policy
Using the 8,4,2,1 weight fair queue scheme:
the output queues will
follow the 8:4:2:1 ratio to transmit packets from the highest to lowest
queue. For example: 8 high queue packets, 4 middle queue packets, 2
low queue packets, the lowest queue packets are transmitted in one
turn.
Use the strict priority scheme:
the packets in the higher queue will
always be transmitted first until a higher queue is empty.
