附录 C. YANG Instance 示例

附录 C. YANG Instance 示例

本节包含一个符合这些 YANG module 的 YANG instance 示例. 该 data instance 的有效性已使用 yangson <https://yangson.labs.nic.cz/> 检查. Yangson 需要一个 YANG library [RFC8525] 来定义用于验证该 data instance 的完整模型. 在附录 D 中, 我们提供了用于验证的 JSON library 文件 "ietf-service-assurance-library.json".

下面给出文件 "example_configuration_instance.json" 的内容, 其中包含用于建模 [RFC9417] 第 3.1 节图 2 的配置数据. 假定本文档中定义的所有文件 (YANG 和 JSON) 都位于当前文件夹, 可以通过调用 "yangson -v example_configuration_instance.json ietf-service-assurance-library.json" 使用 yangson 验证该 instance.
