Scenario details: Verifying that the policy is working

 

You need to use the monitor to verify that the policy is working as you configured it to work.

  1. On the Quality of Service (QoS) Server Configuration window, select Server > Monitor. The QoS Monitor window opens.

  2. Select the Differentiated Services policy type. This displays all the Differentiated Services policies.

    Similar to example 1, the most interesting fields are the fields that obtain their data from your traffic. These fields include the bits total, bits in-profile, and packets out-of-profile fields. Bits out-of-profile indicate when traffic exceeds the configured policy values. The in-profile packets indicate the number of packets controlled by this policy. What values you assign the average rate limit field is very important. When TCP packets exceed this limit, they are sent into the network, until the TCP congestion window can be reduced to queue out-of-profile packets. As a result, the bits out-of-profile increase. The difference between this policy and the Limit browser traffic scenario is that the packets here are protected using the VPN protocol. As you can see, QoS does work with a VPN connection. See Monitoring QoS for a description of all the monitor fields.

    Remember that the results are only accurate when the policy is active. Verify the schedule you specified within the policy.
