You can use four core topologies to model your IT infrastructure in
DX NetOps Spectrum:
All four of these topologies are available from the Navigation panel.
We recommend that you begin modeling with the Universe topology. After you have established one or more modeled elements in the Universe topology, you can reuse these modeled elements to define the other topologies.
To navigate through the model views of any topology, click the view control iconsin the toolbar. In some cases, you can click an aggregate icon container to view its content.
The Universetopology helps you organize an enterprise network view of your infrastructure. Most often, it provides a view of:
- A top-level topology view of OSI Layer 3 devices and their connections
- A drill-down topology view of OSI Layer 2 devices and their connections
- A Component Detail view, showing the attributes that are associated with a modeled entity
The top view in the Universe topology typically includes:
- TheDX NetOps SpectrumVirtual Network Machine (VNM)
- Network groupings
- Network segments
- OSI Layer 3 devices and their connections
The following illustration shows a typical top view:
The following illustration shows a drill-down view of a LAN container that is selected from the top view. A drill-down view in the Universe topology most often includes all OSI Layer 2 devices and their connections. The drill-down view also shows off-page references to devices modeled in other views, as shown in the following illustration:
Component Detail Panel
The Component Detail panel within the Universe topology identifies the attributes that are associated with a modeled network entity. Attributes can include the device interfaces, alarms and events, and other pertinent device information.
You can view the device attributes and possibly change their settings by clicking the Component Detail panel tabs. Depending on the context of the Contents panel, you can use the Component Detail panel to:
- View current alarms in the Alarm Details tab.
- View and modify general device settings in the Information tab. For example, grant or deny access to a modeled device by providing or possibly removing a security string.
- View root cause analysis data in the Root Cause tab.
- View CPU and memory utilization information in the Performance tab.
- View device interface information in the Interfaces tab.
- View neighboring routers in the Neighbors tab.
- View historical events in the Events tab.
- View attribute information from the Attributes tab. This information appears only under these conditions:
- You select an entity from the Explorer tab.
- You are in either the Topology, List, or Events tab in the Contents panel.
Define Models in the Universe Topology
You can define models in the Universe topology using the OneClick Discovery feature, which automates the modeling process for you. You can also manually define new models or edit existing models in the Universe topology by using the modeling tools that are provided with OneClick.
The Universe topology view represents a true connectivity view of your infrastructure. Therefore, we strongly recommend that you reuse modeled elements from this view when creating other views. Therefore, as a best practice, copy model elements from the Universe topology view to create Global Collections, World, or TopOrg views. This approach helps to ensure accurate fault isolation of your network within the OneClick environment.
Global Collections Topology
landscapeis the network domain that is managed by a single
SpectroSERVER. In OneClick, a landscape is the network view of one
SpectroSERVER. To organize entity-based network views that span one or more landscapes, use Global Collections. Global collections enable you to monitor all aspects of your IT infrastructure from any perspective.
As an administrator, you can use Global Collections to create and track collections of network entities, organizations, or services that make up your infrastructure. For example, you can create and maintain collections that identify and track:
- Response teams within an organization responsible for maintaining equipment
- Devices supporting various services in your organization
- Customers receiving services from your organization
View or Modify Modeled Devices
You can view and change modeled device attributes or settings in the Component Detail panel within a Global Collections topology. Click the tabs in this panel for general information about a device, its interfaces, alarms, events, and other pertinent information.
The Worldtopology helps organize your network geographically in OneClick. In this topology, you can represent device models of network locations from a national or regional level all the way down to a wiring closet.
The following example illustrates a drill-down view of an equipment room that is at a fictitious North Dallas location.
In the World topology, you can create several layers of views that represent locations of your network devices. For example, you can have views for Texas regional offices, Dallas office, and Dallas Equipment room. Additionally, the Component Detail panel lets you view and sometimes change the attributes that are associated with a modeled device in any World topology view. For instance, clicking the Component Detail tabs for a modeled device lets you view device information, interfaces, alarms, events, and other pertinent device information.
- When populating the World topology views with modeled devices, we highly recommend that youcopy and paste modeled elements from Universe topology views. Universe topology views represent the true connectivity views of your infrastructure, helping to ensure accurate fault isolation of your network within the OneClick environment.
- The Cut, Copy, Paste and Delete functionality for VHM models is disabled by default. If required, you can enable the option by following the steps explained in the ‘Cut, Copy, Paste and Delete Functionality for VHM Models’ section.
The TopOrg topology allows you to represent your network organizationally. In this topology, you can group subnets and device models by services, responsibilities, departments, or by other organizational considerations.
The following illustration displays an organizational view that identifies individuals and groups within a fictitious Finance Department. This type of view is useful when identifying how a network failure or a reconfiguration affects an organizational unit.
If you purchased the Service Manager module, you can use this module with the TopOrg topology to model business services and applications. Further, the Service Manager module also tracks the performance of the service against a contract or Service Level Agreement (SLA).
For more information about using the Service Manager module, see
In the TopOrg topology, you can create several layers of views that represent various levels of your network devices. For example, you can have views for Enterprise ownership, Department ownership, supporting devices, and supporting services. Additionally, the Component Detail panel lets you view and possibly change the attributes that are associated with a modeled device in any TopOrg topology view.
When populating the TopOrg topology views with modeled devices, we recommend that you copy and paste modeled elements from Universe topology views. Universe topology views represent the true connectivity views of your infrastructure. Therefore, using them as your base for all other views helps ensure more accurate fault isolation of your network within the OneClick environment.
The following table describes some of the buttons available in the Topology tab toolbar for working with topologies.
Edit mode:Click to put the current topology view into Edit mode.
Create new model by type:Click to create a new model by type and add it to the topology view.
Create new model by IP:Click to create a new model by IP address or Host Name. Click the down arrow and select one of the following options:
Create By IP
Create By Host Name
Discovery:Click to create a new discovery based on the selected model or models.
Spotlight View:Click to highlight all models related to a VPN, a VLAN, or router redundancy in the Topology view. Spotlighting allows you to easily determine relationships between these items and your network, and between these items and other models on your network. When you click the Spotlight view button, a menu appears containing the following options:
Remove Model:Click to remove the selected model from the Topology view.
