Systems and methods for merging configurations on network devices based on structured models representing features to be configured are disclosed. By utilizing these structured models embodiments may generally allow configuration merges to be performed substantially on a per feature basis and also allow the merging to be performed in a manner that minimizes conflicts and implementation complexity while substantially improving the performance of those configuration merges.

Merging configurations of network devices

Functionality in a network device is specified by an application installation file that describes programmable devices used to implement the functionality. Profiles for programmable devices generated from the application installation file and stored on the network device. A profile database stores profiles associated with functionality specified in previously received application installation files. A profile associated with a selected functionality is selected to implement the selected functionality, including loading one or more bitfiles identified in the selected profile to program the programmable devices associated with the selected functionality.

Profile registry and resource management

In some embodiments, a method or processing a command line interface is provided. The method parses a definition file for extending a command line interface (CLI) with an extension. The definition file is processed through an external interface that is different from an internal interface used to develop the CLI. The method translates a definition from the definition file to an internal structure supported by the internal interface. The translated definition implements the extension in the CLI. The internal structure is added to a data structure for the CLI where a command set of the CLI is extended to perform a command that is defined by the definition.

Command line interface extension process

Techniques for implementing an improved command line interface (CLI) are provided. In certain embodiments, this improved CLI can provide a CLI command definition language that enables developers, users, and/or other entities to define CLI commands in a straightforward and flexible manner, create optimized parse graphs based on the CLI command definitions, and employ an efficient algorithm for traversing a parse graph at, e.g., CLI runtime in order to parse an input text string and match that string to a valid CLI command.

Techniques for implementing a command line interface

A method and system for processing commands on a network device. The method may include instantiating a command execution back end that includes a parser, an activity thread, and a command execution server thread; receiving a connection; instantiating a command execution front end including a controlling terminal; detecting the instantiation of the command execution front end; creating a connection thread including an input communication channel, an output communication channel, an error communication channel, and a thread local working directory; receiving signal socket information, arguments socket information, connection environment information, a user identifier, a group identifier; a name of the controlling terminal, and a connection type; receiving additional command execution information; receiving a command; sending the command from the command execution front end to the connection thread; parsing the command using the parser; executing the parsed command to obtain a result; and providing the result to the command execution front end.
