Description

Port-base: the output priority is determined by ingress
port.

COS only: the output priority is determined by COS only.

TOS only: the output priority is determined by TOS only.

COS first: the output priority is determined by COS and
TOS, but COS first.

TOS first: the output priority is determined by COS and
TOS, but TOS first.

Using the 8,4,2,1 weight fair queue scheme: the
output queues will follow 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, and the one lowest queue packets are
transmitted in one turn.

Use the strict priority scheme: always the packets in
higher queue will be transmitted first until higher queue is
empty.
