Configuration result:
An ACL name 1 is set to matching segment 192.168.1.0. Enable QoS globally, create a class
map named c1, matching ACL1 in class map; create another policy map named p1 and refer
to c1 in p1, set appropriate policies to limit bandwidth and burst value. Apply this policy map on
port ethernet1/2. After the above settings done, bandwidth for packets from segment
192.168.1.0 through port ethernet 1/2 is set to 10 Mb/s, with a burst value of 4 MB, all packets
exceed this bandwidth setting in that segment will be dropped.

As shown in the figure, inside the block is a QoS domain, Switch 1 classifies different traffics
and assigns different IP precedences. For example, set CoS precedence for packets from
segment 192.168.1.0 to 5 on port ethernet1/1. The port connecting to switch 2 is a trunk port.
In Switch 2, set port ethernet 1/1 that connecting to swtich1 to trust cos. Thus inside the QoS
domain, packets of different priorities will go to different queues and get a different bandwidth.
The configuration steps are listed below:
