Abstract
Methods and devices are disclosed for determining differences in the configuration states of network devices. Context-sensitive diffs are produced by comparing two configuration files of a network device. According to some aspects of the invention, the context of each command is preserved in a “programmatic” format that is usable by a network element such as a router. In some aspects of the invention, only commands at a corresponding hierarchical level of the configuration files are compared when producing a diff, in order to increase accuracy and efficiency.
