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 ethernet 1/2. 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.
Scenario 3:
Fig 13-3 Typical QoS topology
As shown in the figure, inside the block is a QoS domain, switch1` classifies different
traffic and assigns different IP precedence. For example, set IP precedence for packets
from segment 192.168.1.0 to 5 on port ethernet 1/1. The port connecting to switch2 is a
trunk port. In Switch2, set port ethernet 1/1 that connecting to swtich1 to trust IP
