A.2e 802.1p Settings
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. By default, the highest priority is seven,
which might be assigned to network-critical traffic. Values five and six may be
applied to delay-sensitive applications such as interactive video and voice. Data
classes four through one range from controlled-load applications down to “loss
eligible” traffic. Zero is the value for unassigned traffic and used as a best effort
default, invoked automatically when no other value has been set.
A packet can match more than one rule. This means that:
The first class rule has precedence over all other class rules (scanning is •
stopped once the first rule is reached).
The first traffic-priority (classless) rule has precedence over all other traffic •
priority rules.
There is no prevention of a traffic-priority rule conflicting with a class rule. In •
this case, the priority and DSCP setting of the class rule (if given) will
take precedence.
