Example 5
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 is policed to 1000000 bps with an allowed 9000 burst value.
Note If you use the match flow ip source-address | destination-address command, these two flows are
consolidated into one flow because they have the same source and destination address.
