10.7 Priority to Queue Mapping
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a
MAC-layer frame that contains bits to define class of service. Frames without an
explicit priority tag are given the default priority of the ingress port. Use the next
screen to configure the priority level-to-physical queue mapping.
The Switch has eight physical queues that you can map to the 8 priority levels. On
the Switch, traffic assigned to higher index queues gets through faster while traffic
in lower index queues is dropped if the network is congested.
