• Bandwidth guarantee—When congestion occurs to a port, class-based queuing (CBQ)
classifies packets into different classes according to user-defined match criteria and assigns
these classes to their queues. Before assigning packets to a queue, CBQ performs bandwidth
restriction check. When being dequeued, packets are scheduled by WFQ.
Advanced queue applies to only outgoing packets of interfaces.
