Scenario details: Monitor your policy

To verify that the traffic is behaving as you configured in the policy, use the monitor.
  1. Select the specific Policies folder (DiffServ, IntServ, Inbound admission).
  2. Right-click the policy that you want to monitor and select Monitor.

The following figure is a list of possible monitor output for the policy set above.

Look for the fields that obtain their data from your traffic. Make sure to check the total bits, bits in-profile, packets in-profile, and bits out-of-profile fields. Bits out-of-profile indicate when traffic exceeds the configured policy values. In a differentiated service policy, the out-of-profile number indicates the number of bytes being dropped. The in-profile packets indicate the number of bytes controlled by this policy (from the time the packet was started to the present monitor output).

What values you assign to the average token rate limit field is also important. When packets exceed this limit, the server will begin to drop them. As a result, the bits out-of-profile will increase. This shows you that the policy is behaving as you configured it to behave. To change the amount of bits out-of-profile, you will need to adjust your performance limits. Monitor QoS provides full descriptions of all the monitor fields.
