Mapping 802.1p Priority
The IEEE 802.1p feature allows traffic prioritization at the MAC level. The switch can prioritize traffic based on
the 802.1p tag attached to the L2 frame. Each port on the switch has multiple queues to give preference to
certain packets over others based on the class of service (CoS) criteria you specify. When a packet is queued
for transmission in a port, the rate at which it is serviced depends on how the queue is configured and
possibly the amount of traffic present in the other queues of the port. If a delay is necessary, packets get held
in the queue until the scheduler authorizes the queue for transmission.
