Unified Data Models

CLI-based YANG data models, also known as unified configuration models are introduced in Cisco IOS XR Software Release 7.0.1. The unified models provide a full coverage of the router functionality, and serves as a single abstraction for YANG and CLI commands. Unified models are generated from the CLI and replaces the native schema-based models.

The unified models are available in pkg/yang location. The presence of um in the model name indicates that the model is a unified model. For example, Cisco-IOS-XR-um-<feature>-cfg.yang.

You can access the models supported on the router using the following command:
Router#run
[node]$cd /pkg/yang
[node:pkg/yang]$ls

The unified models are also available in the Github repository.

Description

Unified Data Model to map script file to the custom OID

 Release 7.5.3

Use the Cisco-IOS-XR-um-script-server-cfg.yang unified data model to map script file to the custom OID.

Unified Data Model to Configure MAC Address

 Release 7.5.3

Use the Cisco-IOS-XR-um-if-mac-address-cfg.yang unified data model to set or delete a Media Access Control (MAC) address of the Management Ethernet interface, which acts as a unique identifier for the device in the network.

New Unified Models

Release 7.5.2

Unified models are CLI-based YANG models that are designed to replace the native schema-based models. This release introduces new unified models to configure the Fabric Interface ASIC (FIA), Link Aggregation Control Protocol (LACP), Cisco Express Forwarding (CEF) and controller fabric.

You can access these new unified models from the Github repository.

Transitioning Native Models to Unified Models (UM)

Release 7.4.1

Unified models are CLI-based YANG models that are designed to replace the native schema-based models. UM models are generated directly from the IOS XR CLIs and mirror them in several ways. This results in improved usability and faster adoption of YANG models.

You can access the new unified models from the Github repository.

The following table lists the unified models supported on Cisco IOS XR routers.
