Interface bandwidth limit—Uses token buckets for traffic control and limits the rate of transmitting
packets (including critical packets) on an interface. When limiting the rate of all packets on an
interface, interface bandwidth limit is a better approach than subnet limit and advanced limit. This
is because working at the IP layer the latter two functions do not take effect on packets not
processed by the IP layer.
•
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.
