4.9.5 CoS
The switch supports four CoS queues for each egress port. For each
queue, you can specify the scheduling types as follows:
•
Strict priority scheduling: each CoS value can map into one of the
four queues. The queue 4 has the highest priority to transmit the
packets. And packets in the low-priority queue do not transmit until
all the high-priority queues become empty. In strict priority
scheduling, weight settings are always zero.
•
Weighted round-robin (WRR) scheduling: WRR scheduling requires
you to specify a number that indicates the importance (weight) of the
queue relative to other CoS queues. WRR scheduling prevents the
low-priority queues from being completely neglected during periods
of high-priority traffic. The WRR scheduling transmits some packets
from each queue in turn. The number of packets it sends
corresponds to the relative importance of the queue. For example, if
one queue has a weight of 3 and another has a weight of 4, three
packets are sent from the first queue for every four that are sent from
the second queue. By using this scheduling, low-priority queues
have the opportunity to send packets even through the high-priority
queues that are not empty. The valid value of weight is from 1 to 255
and weight settings only effective for WRR scheduling.
