Example 2:
In port ethernet1/2, set the bandwidth for packets from segment 192.168.1.0 to 10 Mb/s, with a
burst value of 4 MB, all packets exceed this bandwidth setting will be dropped.
The configuration steps are listed below:
Switch#config
Switch(config)#access-list 1 permit 192.168.1.0 0.0.0.255
Switch(config)#class-map c1
Switch(Config-ClassMap-c1)#match access-group 1
Switch(Config-ClassMap-c1)#exit
Switch(config)#policy-map p1
Switch(Config-PolicyMap-p1)#class c1
Switch(Config-PolicyMap-p1-Class-c1)#policy 10000 4000 exceed-action drop
Switch(Config-PolicyMap-p1-Class-c1)#exit
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.
