priorities are defined in IEEE 802.1p. The default priority levels are
assigned according to recommendations in the IEEE 802.1p standard as
shown in the following table.
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.
