Exploring the SR OS YANG models

Introduction

This article describes the SR OS YANG package that is delivered from Nokia.

Nokia delivers the YANG models in the following directory structure:

YANG
+-- ietf
+-- nokia-combined
+-- nokia-submodule
+-- openconfig

The contents of each directory are as follows:

YANG (root) - The root of the Nokia YANG package: includes models for bof/li/operations, types and augments. For info: the Nokia YANG models for Lawful Interception (the YANG models for LI will be delivered in all geographic regions whether or not LI is available in SR OS)
YANG/openconfig - The OpenConfig models for integration with SR OS devices.
YANG/nokia-combined - The Nokia YANG models collapsed into two files: one for configuration and one for state.
YANG/nokia-submodule - The Nokia YANG models defined in submodules, used for compilation into two files: one for configuration and one for state.
YANG/ietf - IETF models for NETCONF infrastructure to interwork with SR OS

Which YANG models should be used depends on the configuration of the SR OS device:

SR OS Configuration	YANG Models
/configure/system/management-interface/yang-modules/nokia-submodules true	YANG/nokia-submodules
/configure/system/management-interface/yang-modules/nokia-combined-modules true	YANG/nokia-combined
