    Creating CFM Profiles

    You can a create a connectivity fault management (CFM) profile that you can use as a starting point for provisioning OAM services. A CFM service is defined as the collection of maintenance end points (MEP), or maintenance intermediate points (MIP) in one maintenance association.

    A service definition provides a template upon which services are built. It specifies service attributes that are not specific to a service instance These service definitions are capable of providing the basis for most of the service orders your organization will need to create. The OAM insight provides a set of predefined service definitions. In case these predefined service definitions are not adequate for all your needs, you can create service definitions of your own.

    You can perform the following tasks with the Manage Profiles page for CFM profiles:

    • Create a CFM profile and define the actions to be performed for the corresponding events.
    • Modify an existing CFM profile to meet the network needs and deployment scenarios.
    • Delete an existing CFM profile.

    Creating a CFM Profile

    A wizard is available to create and modify a service order in an intuitive and easily-navigable format. The settings that you can configure in the service order are organized in separate pages of the wizard, which you can launch by clicking the appropriate buttons at the top of the Create or Edit a CFM Profile page. Alternatively, you can proceed to the corresponding setting-related pages by clicking the Back and Next buttons at any point in the wizard during the creation of the service order.

    To create a CFM profile:

    1. From the View selector, select Device View.

      The workspaces that are applicable to this view are displayed.

    2. From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.

      The functionalities that you can configure in this mode are displayed in the task pane.

    3. From the View pane, click the plus sign (+) beside the My Network item in the View pane to expand the tree and select the device node you want for which you want to create the CFM profile.

      The device type selected within the device model tree is highlighted.

    4. From the Tasks pane, select the name of the profile that you want to create. To create a CFM profile for a device, select Profiles > OAM.

      The Manage OAM Profiles page is displayed.

    5. Click the New icon at the top of the page.

      The Select Profile Type dialog box is displayed, listing the types of OAM profiles that you can create for the selected device.

    6. Select the CFM Profile radio button from the Select Profile Type dialog box.

      The General Settings page of the CFM Profile creation wizard is displayed.

    Reviewing the Configured CFM Profile Settings

    The Review page of the CFM Profile creation and modification wizards enable you to view and evaluate the service parameters and components you configured in preceding steps or pages of the wizard. This page provides a comprehensive, single-page view of all the service elements configured in the different pages of the wizard. You can either click the buttons corresponding to the various settings at the top of the wizard page to directly traverse to the page you want to modify or click the navigation buttons at the bottom of the wizard page to go to the different pages of the wizard.

    To review the configured CFM profile settings:
