Within the wizards, you need to set the performance limits that are based on individual network requirements.
Objectives
To set these limits,
you really need to understand your current network performance. Because you are trying to configure quality of service (QoS) policies, you probably already have a good idea of your current network needs. To determine exact rate limits,
such as token bucket rate, you might want to monitor all the traffic on your system so that you can better determine what rate limits to set.
Solution
Create a very broad differentiated service policy that does not contain restrictions (no maximum values), and is applied to all interfaces and all IP addresses.
Use the QoS monitor to record data on this policy.
- Scenario details: Opening QoS within iSeries Navigator
This topic contains information about opening QoS within iSeries™ Navigator.
- Scenario details: Creating a differentiated service policy
Because you want to collect most traffic entering your network, you might call the policy network. Use all IP addresses, all ports, all local IP addresses, and all times (if appropriate).
- Scenario details: Completing a new class of service
While completing the wizard, you are asked to assign a per-hop behavior, performance limits, and out-of-profile traffic handling. This is defined in a class of service. Choose extremely large values to allow as much traffic flow as possible.
- Scenario details: Monitoring your policy
You can use the monitor to verify that the traffic is behaving as you configured it to work in the policy.
- Scenario details: Changing values
After you monitor, you can change any of the values that you previously selected. Right-click the class of service name you created in this policy. When you select Properties, a QoS Properties window opens with the values that control your traffic.
- Scenario details: Monitoring the policy again
After seeing the results, use the guess and check method to find the best limits for your network needs.
