System limitations for NETCONF
The following are the system limitations for NETCONF.
• Only one NETCONF session is supported at a time. Any new NETCONF connection requests are
rejected after the first session is established.
• Only the configuration data store is supported.
• The configuration data store displays the commands that are currently supported
by NETCONF.
• The NETCONF notifications are not supported.
• A partial set of configuration and state display commands are supported.
• The XPATH filtering is not supported.
• A 32K response size limit is supported. An error is returned, if the response size limit is
exceeded.
• A 16K request buffer limit is supported. An error is returned, if the request size limit is
exceeded.
• Only a subset of the subtree filtering is supported.
Data models and mapping
YANG is a data modeling language used to model configuration and state data manipulated by the
NETCONF protocol, NETCONF remote procedure calls, and NETCONF notifications. In order for
NETCONF to be an interoperable protocol, models must be defined in a vendor-neutral language.
YANG provides the language and rules for defining models for use with NETCONF.
The YANG language is currently being developed by the IETF NETCONF Data Modeling Language
Working Group (NETMOD) and is defined in RFC 6020.
Each block of YANG data is encapsulated as a module, containing a header statement, linkage
information, meta information, and revision history. Modules can contain one or more submodules
with the same structure.
