Configuring NETCONF
Overview
Network Configuration Protocol (NETCONF) is an XML-based network management protocol with good
filtering capabilities. It provides programmable mechanisms to manage and configure network devices.
Through NETCONF, you can configure device parameters, retrieve parameter values, and get statistics
information.
In NETCONF messages, each data item is contained in a fixed element. This enables different devices of
the same vendor to provide the same access method and the same result presentation method. For the
devices of different vendors, XML mapping in NETCONF messages can achieve the same effect. For a
network environment containing different devices regardless of vendors, you can develop a
NETCONF-based NMS system to configure and manage devices in a simple and effective way.
NETCONF structure
NETCONF has four layers: content layer, operations layer, RPC layer, and transport protocol layer.

Description
Content
Configuration data,
status data, and
statistics information
The content layer contains a set of managed objects, which can be
configuration data, status data, and statistics information. For more
information about the operable data, see the NETCONF XML API
reference for the switch.
Operations
The operations layer defines a set of base operations invoked as RPC
methods with XML-encoded parameters. NETCONF base operations
include data retrieval operations, configuration operations, lock
operations, and session operations. For the device supported
operations, see "
Appendix A Supported NETCONF operations
."
RPC
The RPC layer provides a simple, transport-independent framing
mechanism for encoding RPCs. The
used to enclose NETCONF requests and responses (data at the
operations layer and the content layer).
Transport
Protocol
•
In non-FIPS
mode:
Console/Telnet/
SSH/TLS
•
In FIPS mode:
Console/SSH/T
LS
The transport protocol layer provides reliable, connection-oriented,
serial data links.
In non-FIPS mode, you can log in through Telnet, SSH, or the console
port to perform NETCONF operations at the CLI.
In FIPS mode, all login methods are the same as in non-FIPS mode except
that you cannot use Telnet.
