Embodiments disclose re-generating a configuration command of a network device. A method includes receiving a request to re-generate a configuration command previously issued to a network device, wherein the configuration command has one or more parameters; retrieving a template and a pattern associated with the configuration command, wherein the template represents a syntax for the configuration command, wherein the pattern represents a storage location for the configuration command; based on the pattern, retrieving from an object database all objects containing values for all the particular parameters from the storage location specified by the pattern; and creating a re-generated configuration command by substituting the values of the retrieved objects into the template.

A flash file system for use with flash cards and internetwork operating system software is provided. Absolute path names are stored in the name field of existing files on flash cards. When the system is initialized, a directory structure is created and stored in RAM by accessing the absolute path names stored in the name field of each file on the flash cards. Accessing a file on a flash card is then accomplished by traversing the directory structure in RAM, and going directly to the precise location of the file on the flash card, thereby minimizing the amount of information that must be retrieved from the flash cards and greatly increasing the speed of accesses. Additionally, cards designed for use with older, non-modular internetwork operating systems may still be used, as name fields for files in these flash cards may easily be used to store absolute path names.
