To modify a VLL service using the topology view

Purpose

The topology view for a service provides a graphical representation of the various components and their interconnections. You can also use this view to add, modify, or just navigate to service components. This provides an alternative approach to performing these functions from the navigation tree view.

Working from the topology view can expedite the creation of the components, since many of the fields you would ordinarily have to set in the configuration forms will be automatically populated using this approach. The configuration forms can also be accessed directly at any time from this view by right-clicking on a component. This allows quick access to conduct more detailed component configuration.

Steps
 

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


Configure the filter criteria. A list of services appears.


Choose a VLL and click Topology View. The Service Topology map opens.

The remainder of this procedure contains a number of sub-procedures describing the various components that can be created and modified from the topology view. These include:

  • Creating a new site. Go to Step 4 .

  • Creating site components. Go to Step 9 .

  • Creating spoke SDP bindings. Go to Step 19 .


Adding a new site
 

Right-click on any blank space in the service topology map. A contextual menu is displayed. Choose the option allowing you to create a new site. This may be an Epipe, Cpipe, Ipipe, Apipe, or Fpipe site, depending on what type of VLL service you are modifying.

The Select Network Elements form appears.


Choose one or more sites to add to the service and click OK. The Site (Create) form for the new site is displayed. If you selected more than one site, the Site (Multiple Instances) (Create) form for the new sites is displayed.


Click OK. The Site (Create) (or Site (Multiple Instances) (Create)) form closes and the new site (or sites) is displayed on the map.


If you want to perform detailed configuration of site properties for the new site, right-click on the site icon and select Properties from the contextual menu. The Site (Edit) form opens. See To configure a VLL site for detailed site configuration information for the various types of VLL services.


Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 27 to finish.


Creating site components
 

Right-click on a site icon or a SAP aggregation group icon in the service topology map. A contextual menu is displayed. Depending on the service type and the icon you clicked on, you can choose to create one of the following:


10 

If you choose to create an Endpoint, the Endpoint (Create) form is displayed.


11 

Configure the Name parameter for the endpoint.


12 

Click OK. The Endpoint (Create) form closes and the new endpoint is displayed in the topology view.


13 

If you choose to create an L2 Access Interface, then the L2 Access Interface (Create) form is displayed.


14 

Click on the Port tab and assign a port to the interface.

If you assign the private port of an ISA tunnel to an Epipe, an L2TPV3 tab is added. On the L2TPV3 tab, select VPRN or Base Router in the Router ID parameter and enter the Tunnel Group name.


15 

Click OK. The L2 Access Interface (Create) form closes.


16 

If you choose to create a SAP aggregation group, then the SAP Aggregation Group (Create) form is displayed.


17 

See To create a SAP aggregation group on a 7705 SAR Apipe for detailed information about configuring the SAP aggregation group.


18 

Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 27 to finish.


Creating spoke SDP bindings
 
19 

Choose the sites you want to connect in the service topology map and right-click on any one of them. A contextual menu is displayed.

Note: When you create a spoke binding between two sites, the order in which you select them is important. The first site you select will become the source site and the second site will become the destination site. Therefore, it is not recommended that you do a marquee-select in the topology view, since you will not be sure of this hierarchy. Instead, select the sites individually, and hold down the Shift or Ctrl key after your first selection.


20 

Choose Connect from the contextual menu and choose the Create Spoke SDP Binding option.

The Spoke SDP Binding (Create) form is displayed.

Note: For this function, it is assumed that you clicked on the source site first and then held down the Shift or Ctrl key while right-clicking on the destination site to display the contextual menu.

You can also create a spoke SDP binding between a site icon and an endpoint icon, or between two endpoint icons in the topology view. Appropriate endpoints must first exist or be created to enable this.


21 

Enable the Auto-Select Transport Tunnel parameter.


22 

You can manually configure other parameters here if required, or click OK. One of the following will result:

  • If an available transport tunnel exists between the two sites, then the Spoke SDP Binding (Create) form closes and the new binding between the two sites is displayed in the topology view. See To configure a spoke SDP binding on a VLL site for more detailed information about creating and configuring spoke SDP bindings for the various types of VLL services.

  • If an available transport tunnel does not exist between the two sites, then an error message is displayed to that affect. See Chapter 33, Service tunnels for information about how to create the required tunnel. When the tunnel is created, you can repeat this sub-procedure.


23 

Assuming that the spoke SDP binding was successfully created in Step 22 , select the same two sites again in the topology view, although this time do so in the opposite order that you originally selected them. This will allow you to create a spoke binding for the return tunnel.


24 

Right-click on the second site you selected and choose the Create Spoke SDP Binding... option from the contextual menu. The Spoke SDP Binding (Create) form is displayed.


25 

You can manually configure other parameters here if required, or click OK. One of the following will result:

  • If an available transport tunnel exists between the two sites, then the Spoke SDP Binding (Create) form closes and the new return binding between the two sites is displayed in the topology view.

  • If an available transport tunnel does not exist between the two sites, then an error message is displayed to that affect. See Chapter 33, Service tunnels for information about how to create the required tunnel. When the tunnel is created, you can repeat this sub-procedure.


26 

Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 27 to finish.


27 

Close the Service Topology form.


28 

Close the Manage Services form.
