YANG-library

The YANG-library capability indicates that a device can provide the YANG capabilities that the device supports. Basic information about YANG modules that a server supports can be viewed on a NETCONF client. The information includes the module name, YANG model version, namespace, and list of submodules and is saved in the local buffer.

Field description:

revision: revision date. It is the same as the module revision date.
module-set-id: module set ID. It indicates a set of YANG modules that the server supports. If a YANG module changes, the ID changes.

XML example: Query the module-set-id value of the YANG module whose name is ietf-yang-library and conformance-type is implement and query basic YANG module information of the YANG module huawei-aaa.

Information contained in the reply includes the module-set-id value, YANG module version used, namespace, list of submodules, and revision date. If the reply does not contain the YANG module version information, YANG1.0 is used by default.
