8.1.2 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.
Finding Out More
See Section 8.6 on page 122 for advanced technical information on QoS.
