How do IETF, OpenConfig, and Cisco native YANG models differ when used to configure the same feature on an infrastructure device?

OpenConfig models are designed to be highly granular and cover a wider array of operational and configuration data points than the more minimalistic IETF standard models. This comprehensiveness allows OpenConfig to specify more detailed configurations and operational state, making them more versatile for multi-vendor environments.

IETF models focus on standardized, core functionalities and are typically less comprehensive than OpenConfig models, which aim to provide a richer, more detailed, and often operational-centric view.

Cisco native YANG models are typically the most comprehensive as they cover all vendor-specific features and functionalities, often exceeding the scope of OpenConfig models for Cisco devices.

Cisco native YANG models are the most comprehensive for Cisco devices, covering all features including proprietary ones, making them more comprehensive than IETF models.
