Viewing Policies

Prerequisites


Caution Caution

When you define multiple meters that may match the same traffic, you must specify the in-profile and out-of-profile traffic as drop or pass to ensure that the traffic is processed at the prescribed rate. If you do not do this, each meter processes the traffic, and this interaction can cause traffic to be treated in unexpected ways.

Use the following procedure to open the Policy tab.

Procedure steps


Step Action

1

From the navigation tree, double-click QoS.

2

From the QoS tree, double-click QoS.

3

Select the Policy tab.

Variable definitions

The following table outlines the parameters of the Policy tab.

QoS Policy tab parameters

Variable Value
Id Specifies the number of the QoS policy.
Status Allows you to enable or disable the policy.
Name Displays the name for the policy.
ClassifierType Specifies whether a classifier or a classifier block identifies traffic.
ClassifierName Specifies the name of the classifier or classifier block associated with this policy.
InterfaceRoles

Specifies the interfaces to which the policy applies.

Note:

You must configure the role combinations prior to associating it with a policy.

InterfaceIndex

Specifies the interface to which the policy is to be applied. A policy is associated with an interface explicitly using this attribute or implicitly using a role combination through the ntnQosPolicyInterfaceRole attribute. An interface must be identified by one and only one of these attributes. This attribute can identify an interface that does not currently exist in the system, as long as the specified interface index represents a potentially valid system interface.

Note:

The InterfaceRoles and InterfaceIndex fields are mutually exclusive. When the InterfaceIndex field is not zero, the InterfaceRoles must be empty (select none when insert the policy). When the InterfaceRoles specifies a valid role combination, the InterfaceIndex field must be 0.

Precedence

Specifies the order in which multiple policies are associated with the same interface. Policies with greater precedence have higher numbers.

Note:

Policies with higher precedence values are applied before policies with lower precedence values.

Meter

Specifies metering associated with this policy. Specifying a metering component causes any action criteria specified explicitly by the policy to be rejected as an error.

Note:

You must configure meters before associating them with a policy.

InProfileAction

Identifies the action to be applied to traffic with this policy. This will not be used when a meter is specified.

Note:

You must configure actions before associating them with a policy.

NonMatchAction Identifies action taken for flows that do not match policy criteria.
StatsType

Specifies statistics tracking:

  • none—no statistics tracked for this policy
  • individual—separate counters allocated, space permitting, for each classifier referenced by the policy
  • aggregate—a single counter accumulates all the statistics for all the classifiers referenced by the policy
SessionId Specifies the numerical identification for the current session.
Storage

Specifies the type of storage:

  • volatile
  • nonVolatile
  • readOnly
Version Specifies the version.

Adding QoS policies

Prerequisites


Caution Caution

When you define multiple meters that may match the same traffic, you must specify the in-profile and out-of-profile traffic as drop or pass to ensure that the traffic is processed at the prescribed rate. If you do not do this, each meter processes the traffic, and this interaction can cause traffic to be treated in unexpected ways.

Use the following procedure to add QoS policies.

Procedure steps


Step Action

1

From the navigation tree, double-click QoS.

2

From the QoS tree, double-click QoS.

3

Select the Policy tab.

4

Click Insert.

The Insert QoS Policy screen opens.

5

Enter the information to use for this QoS policy.

6

Click Insert.

Note:

The InterfaceRoles and InterfaceIndex fields are mutually exclusive. When the InterfaceIndex field is not zero, the InterfaceRoles must be empty (select none when inserting the policy). When the InterfaceRoles specifies a valid role combination, the InterfaceIndex field must be 0.

Deleting QoS policies

Prerequisites

Use the following procedure to delete QoS policies.

Procedure steps


Step Action

1

From the navigation tree, double-click QoS.

2

From the QoS tree, double-click QoS.

3

Select the Policy tab.

4

Highlight the QoS policy to delete.

5

Click Delete.

Viewing QoS Policy Stats

Prerequisites

Use the following procedure to view QoS Policy Stats information for a policy.

Procedure steps


Step Action

1

From the navigation tree, double-click QoS.

2

From the QoS tree, double-click QoS.

3

Select the Policy tab.

4

Select a policy from the list.

5

Click Graph. The Policy Aggregate Stats window opens.

Note:

When StatsType is aggregate, the aggregate stats are available.
When StatsType is individual, the individual stats are available.
