Set-2 Rules contain the following:
802.1p Priority: the 802.1p header includes a 3-bit
prioritization field, which allows packets to be grouped into
eight levels of priority (0-7), where level 7 is the highest one.
QoS-DSCP Setting
In order to understand the differentiated services code point
(DSCP), you should be familiar with the differentiated services
model (Diffserv).
Diffserv is a class of service (CoS) model that enhances
best-effort Internet services via differentiating traffic by users,
service requirements and other criteria. Packets are specifically
marked, allowing network nodes to provide different levels of
service, via priority queuing or bandwidth allocation, or by
choosing dedicated routes for specific traffic flows.
As displayed in following diagram, the IPV4 packet has a TOS
filed. Diffserv defines TOS field in IP packet headers referred to
as DSCP. Hosts or routes that pass traffic to a Diffserv-enabled
network typically mark each transmitted packet with an
appropriate DSCP. The DSCP markings are used by Diffserv
