Description
QOS policy
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.
Priority Mode
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:
