2 What is NETCONF?
Figure 1: NETCONF Concepts and Implementation
• The Transport Protocol layer provides connectivity between the device and the NETCONF client. RUGGEDCOM
ROX II supports the use of Secure Shell (SSH) for the connection.
• The Remote Procedure Call layer represents NETCONF requests and responses. Requests from the client to the
device are wrapped within
<rpc>
elements in the XML query text. Responses from the device to the client are
wrapped within
<rpc-reply>
elements in the XML response text.
• The Operations layer represents actions and functions performed on the RUGGEDCOM ROX II server. The
operations available for use are defined by the NETCONF capabilities advertised by the device.
• The Content layer represents the configuration data on the device. NETCONF can query, manipulate,
and monitor the configuration data on the device. The configuration data is defined by the RUGGEDCOM
namespaces . The configuration data is structured in NETCONF in the same way as it is in the RUGGEDCOM ROX
II web interface and command line interface (CLI).
The NETCONF protocol is defined in several Internet Engineering Task Force Request For Comment (RFC)
documents. It is not necessary to read the RFCs to use NETCONF with devices, but this guide provides links to the
RFCs for those interested in the design details of the NETCONF protocol.
For more general background information on NETCONF, refer to the
Internet Engineering Task Force RFC 6241
[http://tools.ietf.org/html/rfc6241]. This RFC, published in June 2011, is the current main defining document for
the NETCONF protocol.
For historical interest, refer to
Internet Engineering Task Force RFC 4741 [http://tools.ietf.org/html/rfc4741]. This
RFC, published in 2006, contains the initial definition of the NETCONF protocol. Note that RFC 6241 obsoletes RFC
4741.
Several additional RFCs define the NETCONF
capabilities and namespaces . Links to these documents appear
throughout Chapter 2, NETCONF Capabilities and Namespaces , where this guide discusses the capabilities and
namespaces supported by devices.
