Setting Queue Scheduling
Queue scheduling is commonly used to resolve the problem that multiple messages
compete for resource when the network congestion happens. The queue scheduling
function puts the packet to the output queue of the port according to the 802.1p
priority of the packet. The mapping relationship between 802.1p priority and output
queue of the port is as shown in Table 379.
