Why do we need NETCONF?

Why do we need NETCONF?

The key with NETCONF protocol is that it was designed to address the shortcomings of existing practices and protocols for configuration management including: Configuration change transactions. Configuration testing and validation support. Selective data retrieval with filtering.

Why is Yang is used for?

Yet Another Next Generation (YANG, /jæŋ/, which rhymes with “hang”) is a data modeling language for the definition of data sent over network management protocols such as the NETCONF and RESTCONF. The data modeling language can be used to model both configuration data as well as state data of network elements. …

Is NETCONF a TCP protocol?

The transport used by NETCONF is TCP based and ties in to security protocols like SSHv2 and TLS.

Which client is used with NETCONF?

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. ietf-netconf-tls-client-server] respectively.

What is the authentication method used of NETCONF?

509 Certificates. Traditionally, and by far the most popular choice, NETCONF uses SSH as a transport protocol and public/private key pairs for authenticating a new connection.

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).

Who uses YANG?

YANG is a data modeling language developed in the IETF. It is used to model configuration and state data manipulated by protocols such as NETCONF and RESTCONF. YANG enables easier management of network elements, such as routers, and is widely used and deployed by many network equipment vendors and network operators.

What is NETCONF and Restconf?

NETCONF provides mechanisms to install, manipulate, and delete the configuration of network devices. RESTCONF (RFC 8040) provides a subset of NETCONF functionality implemented on top of HTTP/HTTPS. Both NETCONF and RESTCONF were developed to manages devices in a standard way.

Is NETCONF an API?

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.

Why is NETCONF important for a session based Network Management Protocol explain?

NETCONF • Network Configuration Protocol (NETCONF) is a session-based network management protocol. NETCONF allows retrieving state data or configuration data and manipulating configuration data on network devices. NETCONF works on SSH transport protocol.
