    Creating and Managing CFM Action Profiles

    You can create a connectivity fault management (CFM) action profile to define event flags and thresholds to be monitored. You can also specify the action to be taken when any of the configured events occur. When the CFM events occur, the router performs the corresponding action based on your specification. You can configure one or more events in the action profile. Alternatively, you can configure an action profile and specify default actions when connectivity to a remote maintenance association endpoint (MEP) fails.

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

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

    Note: Default Action Profile is a predefined action profile.

    Creating a CFM Action 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 Action 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 action 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 action 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 action 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 Action Profile radio button from the Select Profile Type dialog box.

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

    Configuring the General Settings of a CFM Action Profile

    To define the attributes of a CFM action profile:

    1. On the General Settings page of the wizard, fill in the fields as indicated in the table.

      Field

      Action

      Name

      Specify the name of the action profile.

      Range: 1 through 50 characters. Space and special characters are allowed.

      Description

      Provide a meaningful description for the action profile.

      Range: 1 through 200 characters. Space and special characters are allowed.

      Default Action

      If you want to be notified that an interface is down, select this option.

      Note: You can either select the Default Action or Configure Event options.

      Configure Event

      If you want notification about any of the following events and actions, select this option. When you select this option, the fields under the Event section of the page are enabled for configuration.

      Select one or more events or actions. You must select at least one event. On the occurrence of any of these events or actions, the system marks the interface down.

      Event

      Configure threshold values for connectivity fault management events in an action profile.

      Interface status tlv

      Select the type of interface status TLV to determine the action to be performed on the received continuity check message (CCM) packets at the MEP:

      • Down—When the incoming CCM packet contains interface status TLV with value down, the action will be triggered for this action-profile.
      • Lower Layer Down—When the incoming CCM packet contains interface status TLV with value lower-layer-down, the action will be triggered for this action-profile.

      Note: Type, Length, and Value (TLVs) are described in the IEEE 802.1ag standard for CFM as a method of encoding variable-length and/or optional information in a PDU. TLVs are not aligned to any particular word or octet boundary. TLVs follow each other with no padding between them.

      The Interface Status TLV indicates the status of the interface on which the MEP transmitting the CCM is configured, or the next-lower interface in the IETF RFC 2863 IF-MIB.

      Connection protection tlv

      Select the type of connection protection TLV:

      • Using working path—If the connection protection TLV is received with a “Protection-in-use” value of SET, then the connection protection TLV should use the protection path.
      • Using protection path—If the connection protection TLV is received with a “Protection-in-use” value of RESET, then the connection protection TLV should use the working path.

      An action profile using “connection-protection-tlv using-protection-path” should apply the parameter for a CFM sessions that is monitoring the working path and an action profile using “connection-protection-tlv using-working-path” should apply the parameter for a CFM session that is monitoring the protection path. Using them in the opposite way could mean drop of service traffic.

      Port status tlv blocked

      Select this check box to trigger an action when the incoming CCM packet contains port status TLV with value blocked. The Port Status TLV indicates the ability of the bridge port on which the transmitting MEP resides to pass ordinary data, regardless of the status of the MAC. When the incoming CCM packet contains port status TLV with value blocked, the action will be triggered for this action-profile.

      Adjacency loss

      Select this check box to configure the defect condition that raises an alarm indication signal when physical connectivity is lost between peer MEPs.

      RDI

      Select this check box to cause the remote defect indication (rdi) event to be triggered whenever CCM packets are received from a remote location with the rdi bit set. This event is cleared and action is reverted when none of the remote MEPs send the CCM packets with the RDI bit.

      Action

      Configure the action or actions to be taken when the connectivity fault event occurs

      Interface down

      Select this check box to brings the interface down when a remote MEP connectivity failure is detected

      Propagate remote mac flush

      Select this check box to cause the propagate remote MAC flush action to be triggered when the incoming CCM packet contains the interface-status TLV with value down

    2. From the General Settings page of the wizard, click Next to proceed to the final step of the wizard, which is to review the configured settings. The Review page of the wizard is displayed.
