Figure 17 shows a simple example of how QoS can be implemented on a
university campus. It shows how traffic receives the appropriate
prioritization and treatment across the network according to the
applications used (traffic type), at which location the end user is located,
and also the port type upon which the data is received. All of this is
determined by the setup of the QoS profiles applied to the Switch port.

See “Utilizing the Traffic Prioritization Features of Your Network” on
page 133 for a further network example.
Some examples of rules that can be set up and added to a QoS profile are
shown in
