Systems and methods for reducing processing resources required for configuration updates in a network device by segregating configuration updates into a first set of direct updates and a second set of updates that require CLI commands. The first set of updates are to vendor-neutral configuration objects that are isomorphically mapped to corresponding native configuration objects. The second set of updates are to vendor-neutral configuration objects that are not isomorphically mapped to corresponding native configuration objects. The first set of updates is forwarded to a configuration agent, which applies them to the configuration stored in the system database. CLI commands that are generated for the second set of updates are forwarded to the configuration agent, which parses them and applies corresponding updates to the system database. The system database confirms successful updates to a configuration module which then updates its own vendor-neutral configuration information.

Achieving consistency in overlay data models transactions with a network device

Embodiments of the present disclosure include systems and methods for determining readiness for switchover operations for network devices. A policy definition specifying a set of criteria and a set of instructions is received. Based on the set of instructions, a first supervisor module is determined whether it is ready for a switchover operation based on the set of criteria. The switchover operation includes a second supervisor module configured as a backup to the first supervisor module taking over for the first supervisor module. A set of conditions are determined whether they are satisfied. When the set of conditions are determined to be satisfied and the first supervisor module is determined to be ready for the switchover operation, the switchover operation is triggered to cause the second supervisor module to take over for the first supervisor module.

Determining readiness for switchover operations for network devices

A network device includes computing resources for utilization by processes hosted by the network device and a computing resources manager. The computing resources manager automatically instantiate a new instance of a first process of the processes upon termination of the first process; makes a determination that the network device has entered an out of computing resources state; and in response to the determination: performs an action set to increase a quantity of the computing resources that are available for allocation to the processes.
