Configuration management method and system

摘要

A method of managing a computer network includes comparing a first configuration file representing a network device configuration at a point in time with a second configuration file representing a network device configuration at an earlier point in time; and indicating when a difference exists between the first configuration file and the second configuration file. A system for managing a computer network comprises a memory in which is stored configuration files corresponding to plural network devices at plural points in time; a database in which is stored a history of configuration file usage; and an agent that retrieves from a network device a configuration file and determines when the configuration file retrieved differs from a stored configuration file corresponding to a different point in time. Alternatively, a system for maintaining configuration of a computer network comprises a data store of configuration files, each stored configuration file holding a configuration of a device at a time; and an agent that downloads a current configuration file holding a current configuration from the device and compares the current configuration with the configuration of the device at the time, storing the current configuration in the data store when the current configuration differs from the configuration of the device at the time and identifying differences to an operator.
