Specifying QoS Settings
CoS profiles enable the grouping of class-of-service (CoS) parameters and apply them to one or more interfaces. Connectivity Services Director provides you with predefined traffic types for each CoS profile that you create. These traffic types represent the most common types of traffic for the device type. Each of these templates has preconfigured values for all CoS parameters based on the typical application requirements. You can change the preconfigured values of these parameters to suit your requirements. To display the CoS Profiles page, in Build mode, select CoS under Profile and Configuration Management in the Tasks pane. The Manage CoS Profiles page appears.
If QoS is enabled on the service definition, configure the QoS Settings of the Site Settings panel of the service order creation wizard.
The QoS profile list displays the QoS profiles that are currently configured in the Manage CoS Profiles page of the Connectivity Services Director application.
A QoS profile classifies traffic into defined service groups to provide the special treatment of traffic across the network service.
Specifying Template Settings
The Template Settings page of the service order creation and modification wizards enables you to associate service templates with an E-Line, E-LAN, and IP service order. You can apply only the templates that are previously configured in a service definition with the corresponding service order. The Template Settings page is available in the service order wizard only if the service definition that you selected to apply to the service order contains a service template. Otherwise, the Template Settings page is not displayed in the service order wizard. You can perform template operations for all endpoints in a service order.
If you defined a service template as the default service template, it is attached to the endpoint by default. You have the flexibility to create and provision a dynamic attribute in a service template. You can mark an attribute of a service template as dynamic, and you can obtain the values for these dynamic attributes from a specific device. To create a dynamic attribute, you must first mark an attribute of a service template as dynamic and then specify the device XPath for the dynamic attribute.
The Template Settings page is displayed before the Review page, which is the final step of the service order wizard.
In the Service Settings page of the Select Service Definition field of the service order creation wizard, you can double-click a service definition name displayed in the table to view the details of the definition in a popup dialog box. You can use this information to determine if the service definition is appropriate for your deployment needs. To filter and sort the display of service templates, enter the name of the template as a match criterion in the Search box and click the Search icon. The page refreshes to display only the template names that match with the search term. You can use the paging controls to navigate across multiple pages of templates as necessary.
All the tasks that you can perform with service templates are presented in the Template Settings page. The page is divided into three panes. The top half of the page displays a table of selected endpoints. All the endpoints or UNIs that you selected in the preceding pages of the service order wizard are displayed in this table. You can configure the template pertaining to only one endpoint at a point in time. If the selected endpoints (in previous pages of the wizard) contained a manually-entered unit number, that number is displayed in the table of selected endpoints. Otherwise, the Auto-pick label is displayed.
The lower half of the page is divided into two panes. The left pane displays the template selection table for the endpoint you selected. All the templates associated with the service definition are displayed. You can add and delete templates using the template selection table. The right pane displays all the parameters that you can modify for a selected service template. All such editable paramters are displayed in a consolidated form of a configuration page. This pane is displayed after you select a template. If any configuration parameter in template is set as a service-specific value, such attributes are not displayed in this pane.
To associate a service template with a service order:
Reviewing the Configured Settings
You can examine and modify the created service order parameters in the Review page of the Create IP Service Order wizard.
If you want to modify a particular section in the review page, click the Edit button corresponding to that section.
