10.1.2  What You Need to Know About QoS
802.1p
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given 
the same priority. 802.1p is a way of managing traffic in a network by grouping similar types of 
traffic together and treating each type as a class. You can use 802.1p to give different priorities to 
different packet types. 
Tagging and Marking
In a QoS class, you can configure whether to add or change the DiffServ Code Point (DSCP) value 
and IEEE 802.1p priority level in a matched packet. When the packet passes through a compatible 
network, the networking device, such as a backbone switch, can provide specific treatment or 
service based on the tag or marker.
