The priority levels recommended in the IEEE 802.1p standard for various network
applications are shown in the following table. However, you can map the priority
levels to the switch’s output queues in any way that benefits application traffic for
your own network.

– Output queue buffer. (Range: 0-3, where 3 is the highest CoS
priority queue)
Web – Cli
