The service-policy type performance monitor command is not issued from global configuration mode; it is issued from interface configuration mode. Cisco Performance Monitor enables you to monitor traffic flow information, such as packet count, byte count, drops, jitter, and roundtrip time (RTT). To configure Cisco Performance Monitor, you must perform the following tasks:
1. Create a flow record.
2. Configure a flow monitor.
3. Create one or more classes.
4. Create a policy.
5. Associate the policy with an interface.

First, create a Performance Monitor flow record by issuing the flow record type performance-monitor command from global configuration mode. The flow record is used to specify the data that will be collected. To configure the flow record, issue match and collect commands.
Next, configure a Performance Monitor flow monitor by issuing the flow monitor type performance-monitor command from global configuration mode. The flow monitor allows you to associate a flow record with a flow exporter. A flow exporter is used to send Performance Monitor data to a remote system.
Third, create one or more classes by issuing the class-map command from global configuration mode. A Performance Monitor class map is configured like any other class map by issuing match statements to specify the classification criteria.
Fourth, create a Performance Monitor policy by issuing the policy-map type performance monitor command from global configuration mode. A Performance Monitor policy associates a class with a flow monitor.
Finally, associate the Performance Monitor policy with an interface by issuing the service-policy type performance-monitor command from interface configuration mode. Issuing this command activates the Performance Monitor policy.
