The NETCONF protocol [RFC6241] defines ways to read configuration and state data from a NETCONF server. Part of the configuration data may not be set by the NETCONF client, but rather by a default value from the data model. In many situations the NETCONF client has a priori knowledge about default data, so the NETCONF server does not need to send it to the client. A priori knowledge can be obtained, e.g., from a document formally describing the data models supported by the NETCONF server.

                   With-defaults Capability for NETCONF


   The Network Configuration Protocol (NETCONF) defines ways to read and    edit configuration data from a NETCONF server.  In some cases, part    of this data may not be set by the NETCONF client, but rather a    default value known to the server is used instead.  In many    situations the NETCONF client has a priori knowledge about default    data, so the NETCONF server does not need to save it in a NETCONF    configuration datastore or send it to the client in a retrieval    operation reply.  In other situations the NETCONF client will need    this data from the server.  Not all server implementations treat this    default data the same way.  This document defines a capability-based    extension to the NETCONF protocol that allows the NETCONF client to    identify how defaults are processed by the server, and also defines    new mechanisms for client control of server processing of default    data.
