View and Manage Discovered/Provisioned Circuits/VCs

Enable and Disable Service Discovery

Cisco EPN Manager uses the service discovery feature to automatically discover the circuits/VCs existing in the network and the circuits/VCs that are provisioned using the Provisioning Wizard.

The service discovery feature is enabled by default. You can choose to disable this feature. If you disable service discovery, all the discovered services in Cisco EPN Manager will be removed. However, the services that were provisioned using Cisco EPN Manager will remain and their state will be 'Missing'. Use the History Settings option to configure the maximum number of versions of a discovered Circuit/VC changes that will be presented in the Circuit/VC History table. You must restart the server to apply the changes.


Note

The History Settings configuration is relevant only for discovered changes in optical circuits.

To disable service discovery:

Procedure

Step 1

From the left side bar, choose Administration > Settings > System Settings, then choose Circuits/VCs > Discovery Settings.

Step 2

Uncheck the Enable Service Discovery check box.

Step 3

Restart Cisco EPN Manager to apply your changes. See Stop and Restart Cisco EPN Manager

Circuit or VC Serviceability State— This value is a combination of the circuit or VC's admin and operational states. The admin state is shown because it impacts service operability. For optical circuits, the admin state also determines whether the Activate and Deactivate actions are available. The operational state is shown to quickly identify whether a service is working or not.

View All Circuits/VCs in Cisco EPN Manager

View a Specific Circuit/VC's Details

Cisco EPN Manager provides different ways to view details about a specific circuit/VC, depending on how much detail you need:

View a Specific Circuit/VC in the Topology Map

When working with circuits/VCs, it is very useful to see how a circuit/VC is deployed within the existing network topology. Cisco EPN Manager overlays the circuit/VC on an existing topology map, clearly indicating the endpoints and midpoints of the circuit/VC, the role of the endpoint (where relevant), and relevant fault information for the circuit/VC. This overlay functionality is available in the geo map as well as the topology map.

For CE and CEM services that use the MPLS TE tunnels to traverse through the network, the underlying tunnel is also displayed in the topology map along with the service overlay. For information about how to assign a MPLS TE tunnel for a CE or CEM service, see Provision EVCs in a Carrier Ethernet Network and Provision Circuit Emulation Services .


Note

  • The overlay cannot be displayed if the discovery state of the circuit is "Missing".

  • A circuit/VC might contain endpoints that cross device groups, meaning that one endpoint might belong to one group and another might belong to a different group. In this case, the full overlay cannot be shown. If an endpoint is not currently shown in the map, a notification link will appear at the top left of the map. Click the link to expand the map to show all the device groups that contain endpoints of the selected circuit/VC.

  • When the overlay is displayed, the Link Type filter is disabled.

To display an overlay of a circuit/VC on the network topology:

Procedure
Step 1

From the left sidebar, choose Maps > Topology Maps > Network Topology.

Step 2

Click the Device Groups button and select the required group.

Step 3

Go to the Circuits/VCs tab to see a list of the circuits/VCs associated with the selected group.

Step 4

Select the circuit/VC you want to see on the map.

The nodes and links that participate in the selected circuit are highlighted in the overlay and the rest of the devices in the map appear disabled. The name of the selected circuit is displayed just below the topology toolbar. To clear the overlay, click the ‘x’ button to the right of the circuit name. For a description of the overlay icons, see the table below.

Cisco EPN Manager discovers existing network circuits/VCs and displays them in the Circuit/VC list. Discovered circuits/VCs are automatically named by the system. The names for EVCs begin with EvcLink_ (for example, EvcLink_Vpls_Bridge_318#318#VFIVPLS2_541549_10.56.23.48#1).

Note
When circuits/VCs are discovered, the system identifies whether they are optical, CE, or L3VPN circuits/VCs, but it cannot identify the exact type of CE circuit/VC. For example, CE circuits/VC will display EVC in the Type column but not the type of EVC, such as EPL, E-LAN, and so on. For optical, the exact type of circuit is displayed.

You can do the following with discovered circuits/VCs:

  • Identify discovered circuits/VCs in the Circuit/VC list by name or in the table of circuits/VCs by state, Discovered .
  • View details about the discovered circuits/VCs in the Circuit/VC 360 view, including the endpoints of the circuit/VC.
  • View an overlay of the circuit/VC on the network topology.
  • View fault information for the circuit/VC.
  • Promote a discovered circuit/VC, after which you can edit or delete it (applies to optical circuits and selected EVCs. See Promote a Discovered Circuit/VC Before Modifying/Deleting.
  • Do a performance test.

Show/Hide Implicit Circuits

A circuit is classified as implicit if it is an underlying or "carrying" circuit of another circuit. For example, an OCHTRAIL circuit could be a carrying circuit (and implicit) for an OCHCC circuit. By default, all circuits are listed in the circuit lists. However, you can hide implicit circuits from the lists, if required. When implicit circuits are hidden, they will not be displayed in the circuit lists but you can see them in the Carrying Circuits tab of the Circuit 360 view.

To hide implicit circuits from the circuit lists:

Procedure
Step 1

From the left sidebar, choose Administration > Settings > System Settings.

Step 2

From the System Settings menu, choose Circuits/VCs > Circuits/VCs Display.

Step 3

Uncheck the Show Implicit Circuits/VCs check box.

Filter and Export the Circuit/VC list Based on a User Defined Field

You can create a user defined field, assign a value to the field, and associate it to a circuit/VC. You can then sort, filter, and export the circuit/VC list based on the user defined field.

For example, if you want to filter the circuit/VC list based on the service impact, you need to:

  • Create a user defined field, named Service Impact

  • Select the circuit/VC to which you want to associate the user defined field, Service Impact

  • Assign the value as Critical, Moderate, or Low for the Service Impact field

  • Sort, filter, and export the circuit/VC list based on the service impact value


Note

You can create a maximum of 10 user defined fields.

Procedure

Step 1

To create a user defined field, do one of the following:

  • Choose Administration > Settings > System Settings > General > User Defined Fields, and then click the '+' icon to create a new label and description. Click Save.

Any orphan cross-connection circuit that is associated with a disconnected node is automatically deleted. If the Discovery State of the circuit remains Partial after the orphan cross-connection circuit is deleted, the circuit is automatically repaired and resynced without the need to do it manually.

Compare and Reconcile Provisioned and Discovered Versions of a Circuit/VC


Note

This functionality is supported for Carrier Ethernet VCs, Circuit Emulation, and Serial services only.

When you provision a circuit/VC using Cisco EPN Manager, the relevant CLI commands are configured on the devices participating in the circuit/VC. After a circuit/VC is provisioned using Cisco EPN Manager, the system discovers the provisioned circuit/VC from the network. In some cases, there might be differences between the provisioned CLI and discovered CLI, for example, if a configuration change was made on a device after provisioning. Cisco EPN Manager allows you to compare the provisioned and discovered versions of a circuit/VC and generate a reconciliation report showing the differences. Based on the report, you can decide whether to keep the discovered version or revert to the provisioned version. If you choose to keep the discovered version, the circuit/VC in the Cisco EPN Manager is synched with this version.

The comparison and reconciliation functionality is accessed from the circuit/VC tables.

The functionality is disabled if the circuit/VC discovery state is Missing or the provisioning state is None, In Progress, or Delete Succeeded.

To compare and reconcile a circuit/VC:

Procedure

Step 1

Open a table of circuits/VCs, either the full table of all circuits/VCs in the system (Inventory > Other > Circuits/VCs and Network Interfaces) or a list of circuits/VCs for a specific device group (Maps > Network Topology > Circuits/VCs tab > Circuits/VCs link).

Step 2

In the circuits/VCs table, locate and select the required circuit/VC.

Step 3

Choose Actions > Reconciliation Report.

A comparison report is displayed, showing the differences in provisioned and discovered attributes on specific devices in the circuit/VC. If there are no differences between the provisioned and discovered attributes, "No data available" is displayed in the report.

Note 

For EVPN based services, EVI parameters like RD, RT, and Control Word are excluded from the report.
Step 4

After you have reviewed the report, you can choose to save the discovered version to the database as the current version of the circuit/VC or to revert to the provisioned version. At the top of the page, select the Provisioned or the Discovered radio button and click Reconcile.

If you chose Provisioned, the circuit/VC will be redeployed and the attribute values of the original provisioned circuit/VC will be configured on the devices. If you chose Discovered, the discovered circuit/VC will be stored in the database and this version will replace the original provisioned version. The provisioning status will indicate whether the reconcile action was successful.

Step 5

If the system requires your input to complete the reconciliation, the Provisioning Wizard will be launched. Fill in the required information and redeploy the circuit/VC.

Initiate a Protection Switch Action on a Circuit (Optical)

You can initiate a protection switch action on an optical circuit to switch over the traffic from one path to another path. For example, the traffic in an optical circuit is flowing through a working path and the working path is damaged. You can initiate a protection switch action on this circuit to switch over the traffic from the working path to the protected path.


Note

You can initiate protection switch actions only on optical circuits in which the 1+1 or 1+1+R protection type is enabled. For more information about the protection types, see Circuit Section Reference for OTN Circuit Types.

You can delete or force delete MPLS TE services that are in the following provisioning states: Planned, Succeeded, Failed, or None. For more information about the provisioning states, see Circuit or VC States.

Note

You cannot delete an MPLS TE service if it is being used by a CEM service or a Carrier Ethernet circuit/VC.

Procedure

Step 1

From the left pane, choose Maps > Topology Maps > Network Topology.

Step 2

Click Device Groups, and then select the location in which the required circuit/VC was created.

Step 3

Close the Device Groups popup window.

Step 4

In the Network Topology window, click Circuits/VCs.

Step 5

In the Circuits/VCs tab, click the Circuits/VCs hyperlink located below the list of circuits/VCs.

Step 6

In the displayed table of circuits/VCs, select the MPLS TE service that you want to delete.

Step 7

Click the delete icon or Force Delete to open the Provisioning Wizard and display information for the selected MPLS TE service.

Step 8

From the Deployment Action drop-down list, choose one of the following option:

  • Preview—View the configurations that will be deployed to the relevant devices before the actual deployment.
  • Deploy—Deploy the changes without previewing them.
Step 9

Click Submit.

  • If you selected Preview in the previous step, Cisco EPN Manager displays a Preview Config page. If you are satisfied with the changes, click Deploy.

  • If you selected Deploy in the previous step, Cisco EPN Manager deploys the configurations to the devices immediately.

To view the details of device configuration of the force deleted services, click the i icon next to the Provisioning column in the History tab in the Circuit/VC 360* window. The i icon is available for all provisioning states, except None.

Cisco EPN Manager displays a confirmation message when the deployment is complete.

Manage Provisioned Network Interfaces

Cisco EPN Manager provides a table of interfaces that have been provisioned as network interfaces (UNIs or ENNIs) so that you can view details for and manage network interfaces independently of provisioned circuits/VCs. The table provides information about each network interface, including its identifying information, the device it belongs to, the actual interface on the device, and the number of services in which the network interface is currently participating.

You can view:

  • The network interfaces in a specific device group (from the Network Topology window).

  • All network interfaces managed by Cisco EPN Manager (from the Inventory menu).

You can edit a network interface by clicking the Edit button. This launches the wizard where you can make changes to the network interfaces as required. Keep in mind that if the network interface is associated with multiple services, your edit operation will affect all of those services.

You can delete a network interface as long as it is not participating in any circuits.

Procedure

Step 1

To view and manage the network interfaces that belong to a specific device group:

  1. In the left sidebar menu, choose Maps > Topology Maps > Network Topology.

  2. Click the Device Groups button and select the required group.

  3. In the Circuits/VCs tab, click the Network Interfaces hyperlink (below the table).

Step 2

To view and manage all network interfaces managed by Cisco EPN Manager, choose Inventory > Other > Network Interfaces.

Delete Network Interfaces

From the Network Interfaces table, you can delete a UNI/ENNI if it is not currently participating in any circuits.

To delete a network interface:

Procedure

Step 1

In the left sidebar, choose Maps > Topology Maps > Network Topology.

Step 2

Click the Device Groups button and select the required group.

Step 3

In the Circuits/VCs tab, click the Network Interfaces hyperlink to display the Network Interfaces table.

Step 4

Select the network interface you want to delete and click the Delete button. If the network interface is participating in one or more circuits/VCs, the Delete button will be disabled. In the No. of Circuits/VCs column, you can see the number of circuits/VCs in which the network interface is included.
