match flow ip
Examples This example shows how to create a flow-based class map associated with a source address:
Switch(config)# class-map match-all c1
Switch(config-cmap)# match flow ip source-address
Switch(config-cmap)# end
Switch#
Switch# show class-map c1
Class Map match-all c1 (id 2)
Match flow ip source-address
Switch#
This example shows how to create a flow-based class map associated with a destination address:
Switch(config)# class-map match-all c1
Switch(config-cmap)# match flow ip destination-address
Switch(config-cmap)# end
Switch#
Switch# show class-map c1
Class Map match-all c1 (id 2)
Match flow ip destination-address
Switch#
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 1 Mbps
with an allowed burst value of 9000 bytes:
Switch# configure terminal
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 fastethernet6/1
Switch(config-if)# service-policy input p1
Switch(config-if)# end
Switch# write memory
Switch# show policy-map interface
