Network Design

Use the Network Design screen to create and manage an overlay network topology. From this screen, you can add circuits, data centers, and branch sites to a network topology, configure LAN, WAN, and management options for elements in the topology, review the topology, and perform related tasks. The network design operations are particularly useful for smaller-scale deployments that include data centers and branch sites.

Network design consists of these major workflows:

  • Create network topology—Create circuits, data centers, and branch sites, in this order. A network topology must include at least one circuit and one data center.
  • Configure device profiles—Configure global parameters and options for LAN, WAN, and management settings.
  • Attach devices profiles—Attach device profiles to devices.
  • Ongoing management—Add elements to the network topology and modify the configuration settings for elements as needed.

Access Network Design Options

To access options for creating or updating a network design, select ConfigurationNetwork Design.

The Network Design screen displays. This screen includes the following items:

  • Create Network Design button—Displays if you have not yet created a network topology. Click to create elements for the network. For more information, see Configure Network Design Elements.
  • Manage Network Design button—Displays if you have created a network topology. Click to modify configuration setting for elements in the network. For more information, see Configure Network Design Elements.
  • Attach Devices button—Click to access options for attaching a device profile to a device, detach a device profile from a device, export device profile configuration values to a CSV file, or modify values in a device profile. For more information, see Attach, Detach, Export, Update Device Profiles.
