Choose Manage→Service Tunnels from the NFM-P main menu. The Manage Service Tunnels search form opens.

Click Create→Ethernet Ring. The Ethernet Ring (Create) form opens.

Configure the required parameters.

If you enable the Auto Create Global MEG parameter, the ETH-CFM tab displays all associated Global MEGs created for this Ethernet ring.

If path discovery generates Ethernet ring paths, then the Auto Create Global MEG, Maintenance Domain ID, CCM Interval, and Run CCM on Create parameters are not propagated to the per-path CFM Continuity Check tab configuration. Auto-generation of a MEG and/or MEPs can be configured on a per-path basis.

Alternatively, if path discovery is not operational (that is, no Ethernet ring paths are populated into the Ethernet ring), then Path CFM Defaults parameters on the General tab are propagated and a MEG and/or MEPs are generated upon manual creation of the Ethernet ring paths.

Click Apply. The Ethernet Ring (Edit) form opens.

Click on the Components tab.

Right-click on Ring Elements and choose one of the following:

1. Create Ethernet Ring Element.

   Perform the following steps:

   1. Create an Ethernet ring element as described in To configure an Ethernet Ring Element . The element displays on the Components tab on the Ethernet Ring form.

      You must create a ring element for each site that will be part of the Ethernet ring.

      The Ethernet ring can only have one element configured as an RPL owner and one element configured as an RPL neighbor. This is configured using the element’s Ring Protection Link Type parameter.

      The parameter values specified in Step 3 are initially populated in the Ethernet Ring Element form when creating a ring element from the Components tab. However, you can change these as required.

   2. Repeat 1 to create the other required ring elements.

      You can create all the ring elements required for the ring in one step; see To configure an Ethernet Ring Element .

   3. Go to Step 7 .

2. Add Existing Element.

   Perform the following steps:

   1. The Select Element form opens.

   2. Click Search, select an element, and click OK.

      The element displays on the Components tab on the Ethernet Ring form.

      You must select a ring element for each site that will be part of the Ethernet ring.

      The Ethernet ring can only have one element configured as an RPL owner and one element configured as an RPL neighbor. This is configured using the element’s Ring Protection Link Type parameter.

      When you add an existing Ethernet endpoint, the parameter values specified in Step 3 are not populated into the properties of that endpoint.

   3. Repeat 1 to 2 to select the other required ring elements.

Create an Ethernet path.

Perform the following steps:

1. Right-click on Paths and choose Create Ethernet Ring Path. The Ethernet Path (Create) form opens.

   You must create a path for each element in the ring. Each element (site) in the ring will therefore have two endpoints from two different paths associated with it.

2. Configure the required parameters.

3. Click on the Endpoints tab to configure the endpoints for the path.

   One and only one endpoint within the entire Ethernet ring must have its Ring Protection Link Type parameter configured as Ring Protection Link End. All other endpoints in the Ethernet ring must have this parameter set to a value of Normal.

4. Configure the required parameters for endpoints A and B.

   Path endpoints cannot be administratively enabled if:

   • the R-APS Tag or Member Port parameters are not configured

   • a MEP is not configured on the path endpoint

5. Select an available path endpoint on endpoints A and B.

Click on the CFM Continuity Check tab to configure a CFM Test for the path.

Modify the parameters in the Global MEG Auto Creation panel, if required.

If path discovery generates Ethernet ring paths, then these parameters are not propagated to individual paths. Auto-generation of a MEG and/or MEPs may be configured on a per-path basis.

Click Select. The Select CFM Test form opens. Perform one of the following:

1. Select the required CFM test.

2. Click Create. The Global Maintenance Entity Group (Create) form opens.

   The Initial CCM Interval for the CFM test you select or create must be set to 10 ms or 100 ms, otherwise the subsequent MEP creation will fail.

   See To create and run a Continuity Check OAM diagnostic test from the STM for information about creating the test.

Click on the Intermediate Services tab to view and specify the intermediate services for the Ethernet path. The services in the list are in an order proceeding from endpoint A to endpoint B.

To add an intermediate service:

1. Click Create. The Select Service form opens.

2. Click Search, select the required service, and click OK.

   The Select Service form closes and the service is displayed in the list on the Intermediate Services tab.

   The NFM-P does not perform a validation to confirm whether the selected service is along the path between the two path endpoints.

3. Repeat 1 to 2 to add another intermediate service, if required.

   If you have an intermediate service highlighted in the list and want to add another service immediately above it, click Insert Component rather than Create. Clicking Create places an additional service to the bottom of the list, whereas clicking Insert Component places it directly above a highlighted service.

   You can change the ordering of intermediate services in the list by selecting a particular service and using the Move Up or Move Down buttons.

Perform this step if you need to create interconnects for sub-rings. The interconnects connect a sub-ring to the main ring.

Perform the following steps:

1. Right-click on Interconnects and choose Create Ethernet Ring Interconnect. The Ethernet Ring Interconnect (Create) form opens.

2. Configure the required parameters.

3. Configure the Element A end node for the interconnect.

   In the Element A panel, select a site, and configure the required parameters.

4. Configure the Element B end node for the interconnect.

   In the Element B panel, select a site, and configure the required parameters.

To automatically create a control service for the Ethernet G.8032 ring, go to Step 14 . To manually create the control service, go to Step 15 .

To automatically create a control service for the Ethernet G.8032 ring:

Perform the following steps:

1. Click Create Control Service. The Create Control Service form opens.

2. Select a customer.

3. Configure the required parameters if your Ethernet ring is an Ethernet Virtual link sub-rings.

4. Select a template.

   Only use the Control Service Template if you need to customize the parameters associated with the sites or SAPs such as the description or name.

   If you need to create a Control Service Template, choose Manage→Templates from the NFM-P main menu. Click Browse Example and select the Ethernet ring example.

   If a template is not specified, all created objects use their default property values.

5. Save your changes and close the form.

Manually create a control service for the Ethernet ring if you did not auto-create one in Step 14 .

Perform the following steps:

1. Perform To create a VPLS to create a control service on a VPLS.

2. Perform To create a VPLS or MVPLS L2 access interface to create an L2 access interface for each path endpoint in the Ethernet ring. Each site in the control VPLS must have two control L2 access interfaces.

   When creating the L2 access interfaces, ensure the following requirements:

   • The Terminating Port and Encap Type parameters must have the same values used to create the particular path endpoint as in Step 7 .

   • The Outer Encapsulation Value and Inner Encapsulation Value parameters for the port in each L2 access interface must be set to the same value as the R-APS Tag (Outer Encapsulation Value) and R-APS Tag (Inner Encapsulation Value) parameters, respectively, that you used for the particular path endpoint in Step 7 . This defines the interface as a control SAP for the Ethernet ring.

Perform To create a VPLS to create data services on the VPLS required for the Ethernet ring. The data service must be a regular VPLS, I-VPLS, or B-VPLS type.

To automatically connect the data services to the Ethernet ring, go to Step 18 . To manually connect the data service, go to Step 19 .

Automatically connect the data service to the Ethernet ring.

Perform the following steps:

1. Select one or more Site icon(s) associated with the data service and choose Connect to Ethernet Ring from the contextual menu. The Connect to Ethernet Ring form opens.

   When you use the Connect to Ethernet Ring function to connect a data service to an Ethernet ring configured with a transit service, the NFM-P creates VLAN-specific SAPs for the data service only on the ring site for which Connect to Ethernet Ring is selected. The transit SAPs on the ring transparently forward traffic through other sites on the service.

2. Select an Ethernet ring.

3. Configure the required parameters.

4. Select a data site template.

   Only use the data site template if you need to create an I-VPLS or B-VPLS type data service.

   If you need to create a data site template, choose Manage→Templates from the NFM-P main menu. Click Browse Example and select the Ethernet ring example.

   If a template is not specified, all created objects use their default property values.

5. Save your changes close the form.

To manually connect the data service to the Ethernet ring, perform To create a VPLS or MVPLS L2 access interface to create an L2 access interface for each path endpoint in the Ethernet ring. Each site in the data service must have at least two L2 access interfaces.

When creating the L2 access interfaces, the Terminating Port and Encap Type parameters must have the same values that were used to create the particular path endpoint in Step 7 .
