Abstract: A controller device includes a memory configured to store a tree structure comprising a plurality of nodes, wherein the tree structure comprises a set of sub-structures, and wherein the tree structure defines a configuration of a network device of a set of network devices such that each node of the plurality of nodes corresponds to a respective resource of the network device. Additionally, the controller device includes processing circuitry configured to receive an instruction to update the configuration of the network device, wherein the instruction to update the configuration of the network device indicates a node of the set of nodes corresponding to the update; and verify, based on a sub-structure of the set of sub-structures corresponding to the node indicated by the instruction, the instruction to update the configuration of the network device.

Abstract: In one example, a network management system discovers a plurality of network devices behind a network address translation device, such as a firewall. The network management system may receive a model of a seed network device, generate a first activation configuration and commit the first activation configuration on the seed network device. The network management system may connect to the seed network device and discover neighboring devices from information in the seed network device. The network management system may connect to the neighboring devices, automatically create a model of the neighboring network devices, generate s activation configurations for the neighboring network devices and commit the activation configurations on the neighboring network devices. The network management system may iterative perform these steps until it discovers all the discoverable network devices behind the network address translation device.

Abstract: A controller device manages a plurality of network devices. The controller device includes a memory comprising a configuration database including a set of stored network device configurations, wherein each stored network device configuration of the set of stored network device configurations corresponds to a network device of the set of network devices. Additionally, the controller device includes processing circuitry configured to receive an intent file corresponding to an intended configuration for the set of network devices; receive a message from a network device of the set of network devices indicating an out-of-band configuration change at the network device; and determine, based on a stored network device configuration corresponding to the network device and an actual configuration of the network device, whether the intent file is compatible with the out-of-band configuration change.
