•
SP: Indicates that traffic scheduling for the selected queue is based strictly
on the queue priority.
•
WRR: Indicates that traffic scheduling for the selected queue is based
strictly on the WRR weights. If WRR is selected, the predefined weights 8, 4,
2 and 1 are assigned to queues 1, 2, 3 and 4 respectively.
•
SP+WRR: Integrates the SP and WRR queues. It applies SP to two groups.
The first group contains the PQ and the second group contains other queues.
If SP+WRR is selected, the PQ is assigned to the Q1 and the predefined
weights 4, 2 and 1 are assigned to Q2, Q3, and Q4 respectively. There is no
limit for PQ, indicating that WRR queues may be starved if PQ is always
sending traffic greater than the maximum bandwidth of the LAN ports.

Configuring the LAN QoS Classification Methods
Traffic Classification is used to classify the traffic through the LAN interfaces to a
given traffic class so that the traffic in need of management can be identified.
