In some examples, a controller includes a graphical user interface. The controller displays, via the graphical user interface, network devices that support a device-independent command selected from one or more device-independent commands, wherein each device-independent command performs one or more operations on supported network devices. The controller receives, via the graphical user interface, user input selecting two or more of the displayed network devices and performs the one or more operations of the selected device-independent command on the selected network devices.

Abstract: Techniques are disclosed for providing a Software Defined Networking (SDN) controller with real-time or near-real time visibility of the operation of data center fabrics to determine whether the DCI was properly configured. For example, an SDN controller receives high-level configuration data that describes a desired state of a network managed by the SDN controller at a high level of abstraction. The SDN controller applies a transformation function to the high-level configuration data to generate a low-level configuration data for network devices configured to implement the desired state of the network. SDN controller configures the SDN controller as a peer to the network devices to obtain one or more routes exchanged between the network devices. The SDN controller sends the low-level configuration data to the network devices to cause the network devices to implement the desired state of the network.
