Switch#
Assume there are two active flows as shown below on the Fast Ethernet 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 a 1000000 bps with an allowed 9000-byte burst
value.
Note If you use the match flow ip so urce -a ddre ss |dest ina tion -a ddr ess command, these two flows are
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.
