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 9-7 Typical QoS topology
As shown in the figure, inside the block is a QoS domain, switchA classifies different
traffics and assigns different IP precedences. For example, set IP precedence for packets
from segment 192.168.1.0 to 5 on port ethernet 1/1. The port connecting to switchB is a
