Configuration change detection in network devices

A recently granted patent (Publication Number: US11968091B1) discloses a method and system for enabling the detection of configuration changes in a network device. The method involves maintaining a configuration counter in a system database of the network device, receiving sets of configuration commands, storing corresponding configuration changes in the database, and incrementing the configuration counter for each set of commands. The system further involves comparing counter values to determine if configuration changes were made by sources other than the configuration module, and sending notifications to configuration clients based on the detected changes.
The network device described in the patent includes processors executing a configuration module and a configuration agent, coupled to a system database. The device is designed to maintain a configuration counter, receive sets of configuration commands, store changes in the database, and increment the counter accordingly. It can differentiate between configuration changes made by the configuration module and other sources, allowing for accurate detection and response to modifications. The system also involves updating a Yang tree maintained by the configuration module to reflect database changes and determine if they involve configuration items. Overall, the patented method and system provide a comprehensive approach to monitoring and managing configuration changes in network devices, ensuring the integrity and security of the network infrastructure.
