QoS-802.1p Setting
The IEEE 802.1p priority marking method is a standard for prioritizing network traffic at the data link/Mac sub-layer
802.1p traffic is simply classified and sent to the destination, with no bandwidth reservations established.
The follow diagram shows the structure of 802.1Q Frame. The 802.1Q header includes a 3-bit prioritization field,
which allows packets to be grouped to be grouped into eight levels of priority (0-7), where level 7 is the highest one.
In addition, DSL maps these eight levels to priority queues, where queue 1 has the highest priority.
