MG-SOFT YANG Explorer Professional Edition

The future of network management and network configuration is here!


MG-SOFT YANG Explorer Professional Edition is special application that lets you load NETCONF YANG or YIN modules and explore their structure and properties in the intuitive graphical user interface.

The software can load any set of standard or vendor-specific YANG 1.1 (RFC 7950) and YANG 1 (RFC 6020) modules (and equivalent YIN modules) and display their contents in a visual manner, where module elements are represented as nodes of different types in a hierarchical tree structure. By expanding the YANG tree and selecting a node in the YANG Tree panel on the left side, its properties and description are displayed in the Node Properties tab in the right side of the main window. In addition, the YANG Source File view and the Textual Data Tree view are also available and let you quickly view the section of the YANG code that defines the selected node/subtree, or the textual tree representation (commonly used in IETF NETMOD publications) of the selected data tree branch, respectively.

YANG Explorer implements a wealth of features that let you effectively explore references between YANG statements within one or more YANG/YIN modules. While exploring YANG modules, it is vital to be able to quickly navigate between a reference of a definition and the definition itself, for example, to be able to go from an “if-feature” statement to the definition of a matching “feature” statement. YANG Explorer now offers such navigation whenever a reference exists. The software also provides a reverse functionality that lets you quickly find all usages of a definition in the loaded YANG/YIN modules, for example, to find all “if-features” that reference a specific “feature” definition. This is supported for “typedef”, “grouping”, “identity”, “feature” and “extension” statements. ‘Leafrefs’ (YANG statements with a “leafref” type) are also an important concept in YANG, and the software now offers a quick way to find all ‘leafrefs’ and their target schema nodes in a module. Furthermore, you can also select any “leaf” or “leaf-list” node in the YANG tree and search for ‘leafrefs’ that reference it by using the “Find Referencing Leafrefs” functionality.

MG-SOFT YANG Explorer can visualize the selected YANG modules in form of a UML (Unified Modeling Language) class diagram. UML class diagram displays different types of YANG nodes as classes, with their attributes, methods and relationships between the classes (e.g., dependency, composition, inheritance, etc.). You can explore the UML objects and their relationships either within the scope of a single or several associated YANG modules. Furthermore, YANG Explorer lets you focus on the desired elements of YANG modules by specifying excludes (excluding specific, user-selected classes) and by setting various display options (to toggle displaying certain types of classes globally, etc.). You can zoom in and out of the UML class diagram, pan the diagram, reposition classes and connections in the diagram, print the diagram on a printer, and save it as an image file for external use.

Last but not least, MG-SOFT YANG Explorer incorporates the RFC 6110-based NETCONF Content Editor and Validator tool. This XML document editor with syntax coloring and auto-complete feature lets you easily compose any type of NETCONF XML document and validate it using the DSDL schemas, which are automatically generated from the selected YANG modules in the background (both, YANG 1.1 and YANG 1 modules are supported). The tool contains templates for composing typical NETCONF document types, such as RPC requests (get, get-config, edit-config,…), entire configuration datastores, RPC replies, etc. By default, the XML documents you are editing are being automatically validated in real-time. The NETCONF Content Editor window displays easy-to-understand error and warning messages if any inconsistencies are detected in the validated document. This way, one can quickly fix all syntax and semantic inconsistencies before saving the document to XML file format.

MG-SOFT YANG Explorer is compliant with the following IETF's RFC documents: RFC 4741, RFC 6020, RFC 6110, RFC 6991, RFC 6241 and RFC 7950.

MG-SOFT YANG Explorer is a Java(TM) application that can be installed and used on Windows, Linux and Mac OS X operating systems with Java Runtime Environment version 7.0 (a.k.a. JRE 1.7) or later installed.

A customer testimonial
"Thank you MG Soft for helping me with a dodgy vendor YANG file. Lost in a sea of errors and frustration, you came right out and told me where the issue was.

The NETCONF Browser is a god send and your support is second to none. Big thanks from a very happy customer."
