Abstract: A system for dynamically managing a configuration file of a switch is provided. During operation, the system can determine one or more groups of line specifications in a specification file. A respective line specification can indicate a format of a respective variant of a configuration command of the switch. The system can then annotate a respective group in the specification file with a corresponding label. Subsequently, the system can associate a respective configuration command of the configuration file with a label of a group based on matching the configuration command with the group.

Abstract: The system receives, from a client, a first request for a document which is parsed based on a syntax. The system parses and returns an initial number of lines of the document, thereby allowing the client to display the parsed initial number of lines in a visible window. Subsequent to successfully parsing a remainder of the lines, the system stores a fully-parsed version. Responsive to a scrolling action in the visible window, the system provides a relevant portion of an unparsed document associated with the first request. Responsive to detecting a termination of the scrolling action, the system receives a second request for parsed lines corresponding to a first set of lines. The system returns the corresponding parsed lines, thereby allowing the client to display the corresponding parsed lines in the visible window.

Abstract: The system determines a syntax for each line in a switch configuration file. The system creates, based on the syntax, one or more groups of line specifications, wherein each line specification in a group includes matching terms or values specified by a user. The system generates and deploys a new configuration to a first device. The system obtains one or more changed lines by determining a difference between a pre-deployment state and a post-deployment state. The system identifies, based on the created groups of line specifications and a set of criteria, other devices to which to deploy the new configuration. A user selects a device of the identified other devices to which to deploy the new configuration. The system deploys the new configuration to the selected device and validates the deployed new configuration. The system displays a second list which indicates whether the deployed new configuration is successfully validated.

Abstract: Examples disclosed herein relate to performing an action based on an advertisement indicator is present in a network packet. In one example, a network packet identified by a network infrastructure device as matching criteria associated with a pre-identified request is received. A parameter within the network packet is identified. A rule is used to determine whether the parameter indicates that an advertisement indicator is present in a flow associated with the network packet. An action is performed based on whether the advertisement indicator is present in the network packet.

The method may further include, detecting, using logic and grammar rules, declarations, definitions, and references of entities in the file and resolving circular references in the file. The resolving includes, determining, as second entities, one or more of the entities that have respective references that lack preceding definitions corresponding to the respective references, and for each second entity of the second entities, prepending a declaration of the second entity before a reference of the second entity to create an updated file.

Abstract: Systems and methods are provided for dynamic grammar augmentation for editing multiple network switch configuration files as a single file. The method includes identifying a first base grammar of a first network switch; identifying a second base grammar of a second network switch; identifying first and second patch grammars for the first and second network switches; generating an augmented grammar based on the first and second patch grammars and the first and second base grammars; identifying a first configuration file for the first network switch; identifying a second configuration file for the second network switch; generating a base merged configuration file, the base merged configuration file representing the first and second configuration files modified according to the augmented grammar.

Abstract: An expression evaluation system is provided. During operation, the system can obtain an encoded expression associated with a user group of a network and evaluate the encoded expression for a first switch to determine a first set of commands that the user group is allowed to execute on the first switch. The encoded expression can encode a set of commands. The system can then determine validity of the first set of commands for the user group by determining whether a respective user of the user group should be allowed to execute the first set of commands on the first switch. If the system identifies an issue with the validity of the first set commands, the system can generate a notification indicating the issue.

Abstract: Examples described herein configure a network based on a centroid configuration of a group of network entities.

Abstract: An example consistent with this disclosure includes a controller that is communicatively coupled to dataflow devices in a network. The controller receives device information from a dataflow device and determines features supported by the dataflow device based, in part, on the device information received from the dataflow device. Using a driver configured to use the features supported by the dataflow device, the controller transmits a command to the dataflow device. The controller then receives a response to the command from the dataflow device. The response to the command may include information that indicates different features are supported by the dataflow device than previously determined. The controller updates its determination of the features supported by the dataflow device and updates the driver used to transmit the command to the dataflow device.

Abstract: A network configuration change validation environment is disclosed. In particular, this disclosure is related to an interface to initiate automated test actions (e.g., network monitoring commands, application monitoring commands, etc.) and to view results in an efficient manner to support a network communication infrastructure. In one example, results of a set of commands executed prior to a configuration change may serve as a baseline and one or more results of the same set of commands may be intelligently compared to the baseline to identify any potential issues that have arisen. For example, as a result of a specific network configuration change or application update. The disclosed network change validation command initiator and validation report viewer represent part of an overall network configuration change validation environment that includes automated techniques such that it may be used within a given change window.
