2. Define a Role Combination:

Add Role---Lists the available roles for defining the role combination.

Choose Empty if you do not want to specify a subcard. If you choose Other the validation does not relate to the subcard properties.

To define a role combination:

1. Choose roles, one at a time, from the Add Role dropdown list. The roles appear in the role combination box. You can enter roles directly into this box.

2. Click the Validate button.

Policy Validation for Role

Select a Role name---Lists the available roles for validation:

Device Preview Page

The Managed Device Preview page and Virtual Device Preview page display basic validation information for coloring and limiting actions in the policies in each role combination defined on the selected device's interfaces.

Note For managed devices, validation is only performed for the roles belonging to the current global service template.

Note A message is displayed at the top of the page if the managed device does not support COPS-PR or COPS-RSVP.

The Virtual Device Preview page displays details of the virtual device, and the selected role combination.

For each policy the following information is displayed:

Role---The role to which the policy belongs.
Policy---The name of the policy.
Direction---The direction of traffic for which the policy applies---incoming, outgoing, or both.
Applicable in Direction---The direction for which policy coloring and limiting actions are applicable.
Capability Mismatch---Device capability mismatches for coloring and limiting actions.

For more validation results:

Click the links in the Capability Mismatch column to display the Policy Utilization page. This page displays details of coloring and limiting capability mismatches for each interface. See Policy Utilization Page.
Click the service template name to display the Service Template Preview page in which you can view how service template definitions will be deployed on the device. See Service Template Preview Page.

Role Preview Page

The Role Preview Page displays information for the devices that have interfaces with the specified role, or with a role combination that includes the specified role as the top priority role.

The following information is displayed:

Role name.
Current global service template name.
The number of devices for which the validation is effective.

Note Validation is effective for devices on which the specified role is defined as the highest priority role in any of role combination defined on that device.

For each policy in the role, the following information is displayed:

Policy---The name of the policy.
Direction---The direction of traffic for which the policy applies---incoming, outgoing, or both.
# Conflicting Devices for Direction In---The number of devices that have coloring and limiting capability mismatches in the In direction.
# Conflicting Devices for Direction Out---The number of devices that have coloring and limiting capability mismatches in the Out direction.

For more validation results:

Click the links in the # Conflicting Devices columns to display the Policy Utilization page. This page displays details of coloring and limiting capability mismatches for each interface. See Policy Utilization Page.
Click the service template name to display the Service Template Preview page. This page shows how service template definitions will be deployed on the devices for which the role validation is effective. See Service Template Preview Page.

Policy Utilization Page

The Policy Utilization page displays details of the coloring and limiting capability mismatches for each device interface for the selected policy.

This page displays the name or type of device, or the role name for which validation is being performed. Details of the selected policy are also displayed.

The following information is displayed for each interface in the corresponding device(s):

Device Name---The name of the device to which the corresponding interface belongs.
Role Combination---The name of the role combination on the corresponding interface.
Interface Name---The name of the interface.
Applicable in Direction---The direction for which policy coloring and limiting actions are applicable.
Capability Mismatch---Capability mismatches for coloring and limiting actions on the corresponding interface.

Note Some of the displayed interfaces might belong to a devices's internal card. Many of these interfaces do not support any QoS capabilities, and cannot have any discovered roles. When validation is performed on pending roles on these interfaces, the validation results are not meaningful.

Service Template Preview Page

The Service Template Preview page shows how service template definitions will be deployed on the selected device(s).

The Service Template Preview page displays the following information:

Device name.
Service template name.
Service Definition table as displayed in the Service Template page. See "Working with Service Templates."
Scheduling Preference table, which displays the number of device interfaces that support each queueing method defined in the service template, for each traffic direction.

Note When there are interfaces that do not support any of the defined queueing methods, an additional Error row appears displaying the corresponding number of interfaces. These interfaces will use their default queueing method.

Drop Preference table, which displays the number of device interfaces that support each drop method defined in the service template, for each traffic direction.
RSVP Parameters table, which displays each integrated service definition and the number of interfaces that support tagging, mode type, and resource allocation for each service.
Service Mapping table, which displays the number of interfaces that support each service mapping definition in each direction.

Note 1q1t is not displayed in the service mapping table. For devices that only support 1q1t, such as Cat5K, the # Supporting Interfaces columns will display only zeros.

Weights table as displayed in the Service Template page. See "Working with Service Templates."
Thresholds table as displayed in the Service Template page. See "Working with Service Templates."

For more validation results:

The Devices Interfaces List displays the following information:

Selected Interfaces---Displays selection check boxes.
Device Name---Name of the device with the corresponding interface.
Role Combination---The role combination for the corresponding interface.
Interface Name---The name of the interface with the selected provisioning parameters.
Scheduling Preference---The name of the queueing method that will be deployed on the corresponding interface. If none of the scheduling preferences defined in the service template match the device capabilities, Error will be displayed. In these cases, the interfaces will use their default queuing method.
Drop Preference---The name of the drop method that will be deployed on the corresponding interface.
Service Mapping---The service mapping for the corresponding interface.

For more validation results:

Select one or more interfaces and click the Selected interfaces complete scheduling capabilities link to display the Interface Capabilities page. See Interface Capabilities Page.

Note Display the Interface Capabilities page to view the default scheduling method for interfaces that do not match the service template scheduling preference.

Interface Capabilities Page

The Interface Capabilities page displays the complete scheduling capabilities for selected interfaces. This page is useful when the Service Template Preview page or Service Template Utilization page has displayed Error for an interface's scheduling preference. This means that there is no match between the service template's scheduling preferences and the interface capabilities. In these cases, the interface uses its default scheduling method, which is displayed in the Interface Capabilities page.

The Interface Capabilities page displays the name of the role or device for which validation is being performed, and the name of the current service template.

The Provisioning Parameters table displays the following information:

Device Name---Name of the device with the corresponding interface.
