as new features exposed with new CLI commands were
available over NETCONF right away; at the same time,
this brought all the drawbacks of CLI to network
automation, including unstructured data and vendor-
specific and proprietary CLI commands. YANG was
created as a standard way to define common data models
for NETCONF.
NETCONF provides a set of operations to manage device
configurations and retrieve status information. These
operations include retrieving, configuring, copying, and
deleting configuration data stores and retrieving
operational data. Depending on the NETCONF
capabilities that are advertised by a device, additional
operations can be supported. Table 12-2 shows a
common set of NETCONF operations.
