The following table describes the items in Figure 75.
The
QoS Status
settings in the ensuing table are informational only: Port,
CoS value, Remark CoS, Remark DSCP and Remark IP Precedence.
QoS Scheduling
The switch support eight CoS queues for each egress port. For each of the
eight queues, two types of scheduling can be configured: Strict Priority and
Weighted Round Robin (WRR).
Strict Priority scheduling is based on the priority of queues. Packets in a
high-priority queue are always sent first and packets in a low-priority
queue are only sent after all the high priority queues are empty.
Weighted RoundRobin (WRR) scheduling is based on the user priority
