Creating dependency network views

Dependency network views show devices that are dependent on specified independent entities. For example, within a radio access network (RAN), base stations are modeled as being dependent on base station controllers. You can create a dependency network view to display all of the base stations dependent on one or more base station controllers.

1. Click the Incident icon and select Network Availability > Network Views > Libraries.
2. Click New View .
3. Complete the General tab as follows:

   Name

   Type a name for the network view, dynamic view, or network view container.

   Important: It is best practice to use network view names containing Latin characters only. Network views names containing non-Latin characters (for example Cyrillic characters) are not supported as they cannot be imported and exported when migrating to a new version of Network Manager.

   Parent

   Select the node under which the view appears in the hierarchy in the Navigation Tree. To display the view on the top level, select NONE.

   Type

   Select Dependency.

   Layout

   Select Orthogonal, Circular, Symmetric, Hierarchical, or Tabular layout.

   Map Icon

   If you want a different icon than the default icon to represent the view, click Browse to browse for an icon.

   Tree Icon

   If you want a different icon than the default icon to represent the view, click Browse to browse for an icon.

   Background Image

   Click Browse to browse for an image to use as the background for the view.

   Background Style

   Specify whether the background image is to be centered or tiled.

   Line Status

   Specify how the lines that represent the links between devices should be rendered.

   You can choose not to display any status, or to display the system default. Alternatively, lines can be colored based on the associated Event Viewer event with the highest severity, and can appear with an additional severity icon.

4. Click the Filter tab. Complete the tab as follows:

   Domain

   Select your network domain.

   Class

   This drop-down lists the classes of independent entity in your network. Select a class from the list. For example, to create a network view that shows all the devices that are dependent on specified RAN base station controllers, select RAN Base Station Controller.

   Connectivity

   Select Default. The network view is displayed using the most appropriate connectivity for the type of collection you selected. You also have the option of specifying one of the other following connectivity options:

   Layer 1

   Displays all physical connections.

   Layer 2

   Displays all switched connections between devices in the topology. A layer 2 view typically shows switch and hub connections.

   Layer 3

   Shows routers and the connections between routers. Switches are not normally displayed.

   Note: If switches have active connections involving layer 3 interfaces, they are included in this layout.

   The connections between devices are displayed as follows:

   • Connections between two layer 3 interfaces are shown as normal.
   • Connections between a layer 3 and a layer 2 interface are shown as being between the layer 3 interface and the subnet to which the layer 2 interface belongs.
   • Connections between two layer 2 interfaces are not shown.

   IP subnets

   Shows all devices within a subnet connected to a subnet cloud. This layout helps to simplify the network map and also helps to make subnet membership clear. If you want to see all connections, select one of the following options:

   • Layer 1 for transmission layer connections.
   • Layer 2 for data link connections.
   • Layer 3 to show all routers and connections between them.

   OSPF

   Displays connections based on discovered OSPF information that includes router roles, area membership, and connectivity.

   Probe

   Displays the probe topology, linking probe sources to probe targets.

   Converged Topology

   Displays the lowest layer links between devices based on all layer 1, 2 and 3 topology data available.

   PIM

   Displays connections based on PIM adjacency information.

   IPMRoute

   Displays connections based on IP Multicast upstream and downstream routing information.

   Microwave

   Shows microwave connections only.

   Logical RAN

   Shows logical RAN connectivity. RAN entities are usually connected by L1 or L2 connections, but this logical connectivity allows an overview of the main RAN entities to be seen. Connections are usually implicit in the discovered data. For example, a base station controller is connected at some level to the base stations it manages. Logical RAN connectivity shows this relationship without any intermediate devices, such as multiplexers.

   No connections

   Does not present any of the discovered connections for the nodes shown in the view.

   LTE Control Plane

   Displays a topology view of the LTE control plane.

   LTE User Plane

   Displays a topology view of the LTE user plane.

   LTE S1-U

   Displays a topology view of LTE S1-U connectivity.

   LTE S5-U

   Displays a topology view of LTE S5-U connectivity.

   LTE S8

   Displays a topology view of LTE S8 connectivity.

   LTE S1-MME

   Displays a topology view of LTE S1-MME connectivity.

   LTE S10

   Displays a topology view of LTE S10 connectivity.

   LTE S11

   Displays a topology view of LTE S11 connectivity.

   LTE SGi

   Displays a topology view of LTE SGi connectivity.

   LTE Gx

   Displays a topology view of LTE Gx connectivity.

   LTE S3

   Displays a topology view of LTE S3 connectivity.

   LTE S4

   Displays a topology view of LTE S4 connectivity.

   LTE S6a

   Displays a topology view of LTE S6a connectivity.

   LTE S13

   Displays a topology view of LTE S13 connectivity.

   LTE X2

   Displays a topology view of LTE X2 connectivity.

   IMS Control Plane

   Displays a topology view of IMS Control Plane connectivity.

   IMX CX

   Displays a topology view of IMX CX connectivity.

   Available independent entities

   Select the independent entities for which you want to display dependent devices and click Select to move them to the Selected independent entities list.

5. Click OK.
   The new view is added to the navigation tree in the Navigation Panel. If you added the view to a container, expand the container node to see the new view in the tree.
