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 802.1p header includes a 3-bit prioritization field, which allows packets to
be grouped into eight levels of priority. P.RG F4202N maps these eight levels
to three main priorities: high, medium and low. By default, values six and seven
are mapped to high priority, which may be assigned to network-critical traffic.
Values four and five are mapped to medium priority, which may be applied to
delay-sensitive applications, such as interactive video and voice. Values three
to zero are mapped to low priority, which may range from controlled-load appli-
cations down to “loss eligible” traffic. The zero value is normally used for best-
effort traffic. It is the default value for traffic with unassigned priority.
