Its operations are realized on top of an easy Remote Procedure Call (RPC) layer. NETCONF uses Extensible Markup Language (XML) based on data encoding for protocol messages. The protocol messages are exchanged on the top of a secure transport protocol. Cisco IOS XE Release 12.X and above.<\/p>\n<h2>Background Information<\/h2>\n<p>Data models provides an alternate and centralized feature to configure Cisco devices instead of using the Cisco Command Line Interface (CLI).<\/p>\n<p><strong>Yet Another Next Generation (YANG) <\/strong>is a standards based data modelling language used to create device configuration requests or the requests for operational data. It has a structured format similar to a computer program that is human readable. It was develop by IETF. It is used for configuration data, state data, RPCs (Operations), and event notifications. YANG node types are Container, Leaf and list.<\/p>\n<p><strong>NETCONF<\/strong> is a based and Extensible Markup Language (XML). XML is both human and machine readable.\u00a0 It was developed by IETF. It is replacement for SNMP, CLI and Scripts. It allows user to monitor the device. Uses remote procedure calls (RPCs) called Operations. Runs over SSH.<\/p>\n<p>Configure the SSH username and password on the device for NETCONF communication access.
