Provisioning an ODU0 Tunnel Job Aid 1

Basics Overview

Transporting network traffic of varying technologies efficiently and cost-effectively while using minimum overhead is a key concept when managing evolved programmable networks.

One method for transporting disparate traffic is to configure optical data unit (ODU) tunnels, which can transport Carrier Ethernet-based data on optical layers of the network. By packaging traffic in ODUs, the system encapsulates the data, regardless of protocol, in data frames. These frames are flexible in size, which allows data package sizes to vary, reducing overhead.

The ODU tunnel provides the route that ODU traffic traverses in the optical network as part of the complete route of an end-to-end service.

Operators with fundamental knowledge of networking and provisioning concepts can provision ODU tunnels by using automated processes.

Optical provisioners can provision ODU0 tunnels, which use a specific bandwidth requiring additional configuration. EPN Manager supports the provisioning of various ODU bandwidths so that you can provision circuits in accordance with customer service level agreements (SLAs), operational or business requirements, or other factors.

This job aid addresses an ODU0 tunnel provisioning process by using Cisco© Evolved Programmable Network Manager (EPN Manager).

Managing OTN Services Over Transport Networks Use Case Scenario

To adapt to ongoing network growth, the company for which you work is replacing its time-division multiplexing (TDM) technology with optical transport network (OTN) technology. Because OTN is a more efficient and scalable technology than TDM, the company will be able to reduce transport costs and continue to meet ever-increasing service demands by using this approach.

To continue supporting TDM-based traffic, the network needs to encapsulate it for transport through the OTN portions of the network.

To support this method of transport, you need to provision an ODU0 tunnel. That way, the network can encapsulate the TDM traffic in flexible service frames, which then traverse the optical technology through the ODU0 tunnel.

You have the service request, which indicates the devices and endpoints that you need to provision, so you are ready to begin.

To start this use case:

Based on your location in the application, open the Provisioning Wizard.

The Customer Section page opens.

Important Note: Beginning on the Customer Section page, the wizard provides a Cancel button. Use caution when canceling the provisioning process. When you cancel, the wizard automatically returns to the initial page with its default settings and discards any information that you have added. The system does not prompt or alert you that it will not retain your changes.

6. On the Customer Section page, in the Customer Name drop-down list, optionally select the name of the customer who will use service, if applicable.

Note: System users can add customers in EPN Manager and associate them with network services during provisioning. This association supports identifying service users during monitoring and troubleshooting activities.

10. To include the interface address for the label switched path (LSP) in the Record Route Object (RRO) for an RESV message, select the Record Route check box.

Tip: When you record the route, each interface on the route adds its LSP label and IP address to a reservation (RESV) message. By reviewing RESV messages, you can track the LSP that the traffic is using when you are troubleshooting the service.

11. To continue, click Next.

The Endpoint Section page opens and the system selects the A endpoint row by default.

Tip: If you open the Endpoint Section page and the endpoint rows do not appear, click Cancel. The wizard returns you to the initial page with its default settings. You need to reenter the data up to the point of opening the Endpoint Section page. The endpoints rows will be available for editing.

12. To select the A endpoint, on the map, click the device with the port that you need to configure.

The system applies the Z icon to the device icon and, in the Z endpoint row, the Device Name field populates with the device name.

14. To configure a protection route, in the Protection Type drop-down list, select the type of

failover process that you want to occur in case the working route, or path, fails.

Note: When you select a protection type, additional sections and fields become available so that you can configure the associated working, protected, or restoration routes or profiles. Configuring protection routes requires specific physical and logical configuration of the devices providing the alternate route. For optimal results, ensure that you understand device configurations before configuring protection routes. When you accept the default selection of 1+0, the working route is unprotected and can result in data loss in case of a failure on the route. For more information, refer to the Cisco Evolved Programmable Network Manager 2.0 User and Administrator Guide.

15. To configure the working, or primary, path for the tunnel, in the Working path section, in the Type drop-down list, select one of the following:

Dynamic, which is the default selection Allows the system to determine and provision the best available working route

Explicit Allows you to select a previously configured route or configure a new route by selecting the devices that will support the working (primary) route When you select Explicit, the system opens additional fields that you can use to select or configure routes.

To select a previously configured route, clear the New check box, and then, in the Select Existing EP drop-down list, select the route.

To configure a new route, in the New Name field, type the route name, and then,

in the list, add the devices that comprise the route in the order that you want the path to follow.

Tip: The route will follow the top down order of the devices in the list. To change the path’s route through the devices: In the list, select a device and click the up or down arrow.

16. To evaluate the CLI commands that the system will send based on the settings, click

Preview.

Tip: Cisco recommends that you preview the CLI commands before deployment to help ensure that provisioning will occur as expected.

Core Software Group Managing OTN Services Over Transport Networks

Provisioning an ODU0 Tunnel Job Aid 14

In the wizard, the Service Summary: Preview Config page opens. The Device field indicates the A endpoint and the Commands field displays the CLI commands that the system will send to the A endpoint device.

Note: When provisioning ODU tunnel services on NCS 4000 devices, you see only one device in the preview because the service is GMPLS-signaled from one end only. In this case, EPNM instructs the first device on how to provision the service, and then the control plane on that device handles provisioning the service end-to-end.

17. To start the provisioning process, in the Service Summary: Preview Config dialog box, click Deploy.

The system starts the provisioning action. When the system has deployed the CLI commands, a system message opens in the wizard, indicating deployment results.

18. To continue, on the Deploy: Response page, click CLOSE.

The message closes, and the system returns to the Provisioning Wizard default start page.

Core Software Group Managing OTN Services Over Transport Networks

Provisioning an ODU0 Tunnel Job Aid 15

19. In the Provisioning Wizard, click Close.

The Provisioning Wizard closes. In the Circuit/VCs list, the system lists the circuit with

a gray Missing icon , which indicates that the system has not yet added or discovered the circuit.

As circuit provisioning progresses, the icon transitions to a gray Partially Discovered

icon .

When the circuit is online and EPN Manager has discovered it, the icon transitions to a

green arrow icon .

Note: When ODU tunnel provisioning is complete, the circuit history display two entries because the EPN Manager circuit discovery process occurs as two separate steps, as follows: Circuit Created

Indicates the service intent that the circuit requires by sending the CLI commands to the device

Circuit Discovered Indicates that EPN Manager has discovered the service on the device

Note: The Circuit Discovered entry can take time to appear because it requires EPN Manager to synchronize with the affected devices, which occurs automatically during the device synchronization process.

At this point, the process is complete and the circuit is available on the network.

Note: The provisioning process can take several minutes to complete. In complex provisioning scenarios, the system can take significantly more time. For example, the timeline will be longer when provisioning a circuit with working and protection route settings combined with a series of working and protected route constraints.

To validate or review the provisioned circuit in more detail, you can use the methods available for validating and evaluating it.

Core Software Group Managing OTN Services Over Transport Networks

Provisioning an ODU0 Tunnel Job Aid 17

Validating and Evaluating Provisioned Circuits

Based on the level of detail that you want to review, EPN Manager presents circuit data, statistics, and performance information by using several methods, including reviewing the topology map or the circuit details.

Note: For additional methods that you can use to validate or review circuit information, refer to the Provisioning and OCH Network Connection job aid.

Reviewing Maps

Topological and geographical maps provide a visual representation of circuit relationships among devices in the network.

To learn more about reviewing information by using maps, refer to the Navigating Cisco EPN Manager 1.2 job aid.

Reviewing Circuit Details

The Circuit/VC 3600 View

The Circuit/VC 3600 View pop-up window provides detailed information about the circuit.

It reports the circuit’s status, statistics, and current alarms, if alarms are occurring. It also presents key relationships and details about the circuit endpoints.

Core Software Group Managing OTN Services Over Transport Networks

Provisioning an ODU0 Tunnel Job Aid 18

To open the view:

In the Circuit/VCs list, click the circuit’s information icon.

Note: When reviewing the information in the pop-up window, keep in mind that the system begins reporting statistical data and alarms based on the system monitoring policies and reporting parameters that administrators or users can configure. Monitoring policies define such parameters as device polling frequency, the types of data to report, and reporting thresholds. This means that you might not see statistics, alarms, or other data immediately after device provisioning.
