Cisco Systems WSC4500X16SFP Manual De Usuario

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 1 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

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

 FastEthernet6/1

  Service-policy input: p1

    Class-map: c1 (match-all)

      2965072 packets

      Match: flow  ip destination-address

      police: Per-interface

        Conform: 6105636 bytes Exceed: 476652528 bytes

    Class-map: class-default (match-any)

      0 packets

      Match: any

Assume that there are two active flows on FastEthernet interface 6/1:

SrcIp          DstIp          IpProt SrcL4Port DstL4Port

--------------------------------------------------------

192.168.10.10  192.168.20.20  20     6789       81

192.168.10.10  192.168.20.20  20     6789       21

With the following configuration, each flow will be policed to 1000000 bps with an allowed 9000 burst 
value.

If you use the match flow ip source-address|destination-address command, these two flows will be 
consolidated into one flow because they have the same source and destination address.

Switch# conf terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)# class-map c1

Switch(config-cmap)# match flow ip source-address ip destination-address ip protocol l4 

Switch(config-cmap)# exit
