What is NETCONF and YANG model?

What is NETCONF and YANG model?

NETCONF is the standard for installing, manipulating and deleting configuration of network devices while YANG is used to model both configuration and state data of network elements. NETCONF is defined for transaction-safe configuration of devices.

What is NETCONF Huawei?

Network Configuration Protocol (NETCONF) is an XML-based network management protocol that provides a programmable method to configure and manage network devices. With the help of such NMS software, NETCONF simplifies device configuration and improves device configuration efficiency.

How do you define YANG model?

YANG is a data modeling language used to model configuration and state data manipulated by the NETCONF protocol (RFC 6241), NETCONF remote procedure calls, and NETCONF notifications. The YANG language was developed by the IETF NETCONF Data Modeling Language Working Group (NETMOD), and is defined in RFC 7950.

What is the role of a NETCONF server?

The Network Configuration Protocol (NETCONF) is a network management protocol developed and standardized by the IETF. NETCONF provides mechanisms to install, manipulate, and delete the configuration of network devices. Its operations are realized on top of a simple Remote Procedure Call (RPC) layer.

What are two benefits of YANG?

YANG models both the configuration and state of key layers of network. Properitary extensions are required less frequently, resulting in easier multi-vendor interoperability. Enables automated operation and policies. Enables rich integration with OSS and other SDN controllers.


Network Configuration Protocol (NETCONF) is a communication mechanism used between the NMS and network devices. All network devices provide standard Application Programming Interface (API), through which the NMS manages these devices using NETCONF.

Is Netconf an API?

What is Netconf client?

The NETCONF Client Model This model supports both the SSH and TLS transport protocols, using the SSH client and TLS client groupings defined in [I-D. ietf-netconf-ssh-client-server] and [I-D.

Why is YANG used?

YANG is a data modeling language used to model configuration, state data, and administrative actions manipulated by the NETCONF protocol. YANG was originally published as RFC 6020 in September 2010. Modern network standards groups such as the Metro Ethernet Forum are adopting YANG as a device configuration standard.


While NETCONF uses XML encoding only, RESTCONF supports both JSON and XML.

What is YANG Leaf?

In YANG, each leaf and leaf-list node includes the type statement to identify the data type for valid data for that node. YANG defines a set of built-in types and also provides the typedef statement for defining a derived type from a base type, which can be either a built-in type or another derived type.

How is a data modeling language used Cisco?

Data models are developed in a standard, industry-defined language, that can define configuration and state information of a network. Cisco IOS XE supports the Yet Another Next Generation (YANG) data modeling language. YANG is primarily used to model the configuration and state data used by NETCONF operations.

What is Yang protocol?

YANG is a data modeling language for the NETCONF configuration management protocol. Together, NETCONF and YANG provide the tools that network administrators need to automate configuration tasks across heterogeneous devices in a software-defined network (SDN).

What is Yang format?

Abstract YANG is a data modeling language used to model configuration and state data manipulated by the Network Configuration Protocol (NETCONF), NETCONF remote procedure calls, and NETCONF notifications. Status of This Memo This is an Internet Standards Track document.

What is Yang network?

YANG (Yet Another Next Generation) is a data modelling language, providing a standardized way to model the operational and configuration data of a network device. YANG, being a language is being protocol independent, can then be converted into any encoding format, e.g. XML or JSON.
