Switch(Config-PolicyMap-p1)#exit
Switch(config)#interface ethernet 1/2
Switch(Config-If-Ethernet1/2)#service-policy input p1
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.
Example 3:
Typical QoS topology
As shown in the figure, inside the block is a QoS domain, Switch1 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 switch2 is a trunk port. In
Switch2, 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 different bandwidth.
The configuration steps are listed below:
QoS configuration in Switch1:
Switch#config
Switch(config)#access-list 1 permit 192.168.1.0 0.0.0.255
