To configure quality of service (QoS) policies, you must use the
QoS wizards located in iSeries™ Navigator.
Here is a list of the wizards and their function:
- 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,
which indirectly controls server bandwidth. The policy performance limits
(which you set) decide if the server can handle the requested bandwidth coming
from the client's RSVP application. You will need RSVP ready routers and applications
to carry out the integrated service policies created in this wizard.
Note: Before
you set up an integrated service policy, you must write your own applications
to use the RSVP protocol.
- New DiffServ policy wizard
- This wizard allows you to differentiate and assign priority to TCP/IP
traffic. You will be 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. In V5R3, your iSeries applications
can receive levels of service based on more specific application information.
For more information, see the differentiated service concept before creating
this policy.
- 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 connections being made to
your server. 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 server from specific clients, specific
server applications, or by URI. In addition, you can enhance server performance.
Note: Before
you set up an inbound policy that uses URIs, you must 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 previously listed.
Access 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:
- In iSeries Navigator,
expand your server .
- Right-click Quality of Service and click Configuration.
Note: 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.
- Complete the steps in the Initial Configuration wizard. If the Initial
Configuration wizard does not open, skip to step 4.
- Select Policies. Right-click IntServ, DiffServ,
or Inbound admission.
- Select New Policy.
