Implementing Quality of Service (QoS) 809
Programming Operations Guide
Configuring QoS policies
A Policy is an association between Devices (interface groups), Rules (IP filter groups), and
Actions. When you create a Policy, you define which Devices are affected, which Rules are
checked, and what Actions are taken on the specified interface.
Policies are applied according to the precedence order that you assign in the Policies screen.
Adding a policy
To add a policy:
1 On the navigation tree, click the Services key and click the Policy Management key.
2
Click the QoS key and click the Policies heading.
3 Click the Add button.
Or, right click the Policies heading and click Add .
The Add Policies screen appears.
4
Configure the Policy parameters according to the following table.
5
Click the Save button.
Table 250 QoS Policy parameters
Attribute Description
Name Enter the name of the Policy.
Filter Select the filter group that is associated with this policy.
You must add a filter group, using the Rules heading, before you can choose it from this box.
Filter Type Shows the type of filter group that is associated with this policy.
This is a read only attribute.
Interface Group Select the Interface group that is associated with this policy.
You must add an interface group, using the Devices heading, before you can choose it from
this box.
Interface Direction Shows the direction of packet flow at the interface to which this policy applies.
This is a read only attribute.
Order Enter the number used to determine the order of precedence for this policy.
Nortel Networks recommends that you consider an order numbering strategy (for the values in
the Order field) as you configure policies. The policies in the Policy Table are arranged in
ascending order according to value in the Order column. By establishing a policy ordering
scheme in multiples of, for example, 10 (Order 10, Order 20, Order 30, Order 40, and so on),
you are able to insert policies in the appropriate filter precedence location and still retain the
precedence of the remaining policies.
Action Select the action that is performed with policy.
You must add an action, using the Actions heading, before you can choose it from this box.
