Configuring QoS with wizards

To configure quality of service (QoS) policies, use the QoS wizards located in iSeries™ Navigator.

Here is a list of the wizards and their functions:

Initial Configuration wizard

This wizard allows you to set up system specific configuration and directory server information.

New IntServ Policy wizard

The new IntServ Policy wizard allows you to create an integrated service policy. This policy admits or denies a ReSerVation Protocol (RSVP) request that indirectly controls server bandwidth. The policy performance limits (that you set) decide whether the system can handle the requested bandwidth coming from the client's RSVP application. You need RSVP-ready routers and applications to carry out the integrated service policies created in this wizard.

Before you set up an integrated service policy, write your own applications to use the RSVP.

New DiffServ Policy wizard

This wizard allows you to differentiate and assign priority to TCP/IP traffic. You are able to differentiate traffic by creating policies. Within a policy, you assign service levels to outgoing traffic based on source/destination IP addresses, ports, applications, and even clients. Your i5/OS^® applications can receive levels of service based on more specific application information.

New Class of Service wizard

Use the Class of Service wizard to set packet markings used by routers and switches within networks. It also assigns performance limits to the traffic leaving your network. You use classes of service with a differentiated service policy and an inbound admission policy.

New Inbound Admission wizard

Use the Inbound Admission wizard to restrict the connections that are made to your system. You can restrict access by TCP/IP address, by application, by local interface, or by Uniform Resource Identifier (URI). This allows a system administrator to control access to your system from specific clients and specific server applications. In addition, you can enhance system performance.

Before you set up an inbound policy that uses URIs, ensure that the application port assigned for the URI matches the listen directive enabled for Fast Response Cache Accelerator (FRCA) in the Apache Web Server configuration.

After you decide which type of policy to create, you can configure the policy by using the appropriate wizard that is previously listed.

Accessing the QoS wizards within iSeries Navigator

You can use these steps to access the QoS wizards and create a policy within iSeries Navigator.

To access the QoS wizards and create a new policy, follow these steps:

1. In iSeries Navigator, expand your system > Network > IP Policies.

2. Right-click Quality of Service and click Configuration.

   The Initial Configuration wizard opens in the following circumstances:

   • This is the first time you are using the QoS graphical user interface (GUI) on this system.

   • You want to manually remove any previous configuration information and start over. This only occurs if the QoS interface is already open.

3. Complete the steps in the Initial Configuration wizard. If the Initial Configuration wizard does not open, skip to step 4.

4. Select Policies. Right-click IntServ, DiffServ, or Inbound admission.

5. Select New Policy.
