Network Configuration (NETCONF) Protocol (RFC 6241) There are both standard (common) YANG data models that apply to all vendors (for example, a request to disable or shut down an ethernet interface should be identical for both Cisco and non-Cisco devices) as well as device (native, vendor specific) data models that facilitate configuring or collecting operational data associated with proprietary vendor features. Several applications are available that can be run on a centralized management platform (for example a laptop) to create these configuration and operational data requests. It has a structured format similar to a computer program that is human readable. YANG is a standards based data modeling language used to create device configuration requests or the requests for operational (show command) data. Yet Another Next Generation (YANG) Data Modeling Language (RFC 6020) A centralized management platform (for example a laptop) can be used to configure or collect data from multiple Cisco devices and the data model architecture allows for automating these proceedures via Python scripting (two additional key benefits). Since the data models are standards based the same procedure can be used to configure or collect data from non-Cisco devices as well which makes them ideal for customers that support multiple vendors. Background Information Data Models - Programmatic and Standards Based Configuration and Monitoringĭata models provide an alternate and centralized way to configure Cisco devices (instead of using the Cisco Command Line Interface (CLI) or Simple Network Management Protocol (SNMP)) and to collect operational data (show commands) from Cisco devices. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. It is the device creating the YANG formatted requests that are sent to the Catalyst 3850 via NETCONF RPC (Remote Proceedure Call) messages to configure and collect data from the Catalyst 3850. It acts as the centralized management platform by utilizing the Yang Explorer application. #THE WEB OPERATION FAILED 0 ERROR POWER SAVE MAC PRO#This is the device that is configured and from which data (show command output) is being collected from via NETCONF/YANG.Ī laptop (Apple MacBook Pro running macOS Sierra 10.12.2 and Google Chrome browser) is used as the NETCONF Client. In this example a stand alone WS-C3850-12X48U switch running Cisco IOS-XE 16.3.3 is used as the NETCONF server. #THE WEB OPERATION FAILED 0 ERROR POWER SAVE MAC SOFTWARE#The information in this document is based on these software and hardware versions: Note: No prior experience with NETCONF, YANG, or Python scripting is required in order to use this document. NETCONF/YANG is supported as of IOS XE 16.3.1 software. The example focuses on lab testing with the Catalyst 3850 however, the information provided also applies to other Cisco IOS XE 16.x platforms such as the Cisco ASR 1000 series routers. #THE WEB OPERATION FAILED 0 ERROR POWER SAVE MAC HOW TO#This document describes how to configure NETCONF/YANG on Cisco IOS XE 16.x based Platforms.
