Example 3
Assume there are two active flows on the Fast Ethernet interface 6/1 with source addresses
192.168.10.20 and 192.168.10.21. The following example shows how to maintain each flow to one
MBps with an allowed burst value of 9000 bytes:
Switch# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# class-map c1
Switch(config-cmap)# match flow ip source-address
Switch(config-cmap)# exit
Switch(config)# policy-map p1
Switch(config-pmap)# class c1
Switch(config-pmap-c)# police 1000000 9000
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface fa6/1
Switch(config-if)# service-policy input p1
Switch(config-if)# end
Switch# write memory
Switch# show policy-map interface

Example 4
Assume there are two active flows on the Fast Ethernet interface 6/1 with destination addresses of
192.168.20.20 and 192.168.20.21. The following example shows how to maintain each flow to one
MBps with an allowed burst value of 9000 bytes:
Switch# conf terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# class-map c1
Switch(config-cmap)# match flow ip destination-address
Switch(config-cmap)# exit
Switch(config)# policy-map p1
