2.2.3 Setting Priority-Output Queue Mapping and Queue Scheduling
Queue scheduling is often used in solving the problem of resource contention during
network congestion.
Each port supports eight outbound queues. The switch can distribute packets into the
target queues according to several types of priority. The following tables show the
mapping between outbound queues and priority schemes.
