<get-data>

The <get-data> operation can be used to retrieve all or specified configuration or status data sets from the NMDA data set.

• source: specifies a configuration database from which data is being retrieved. If the database name is <ietf-datastores:running/>, <ietf-datastores:candidate/> or <ietf-datastores:startup/>, the configuration data is returned. If the database name is <ietf-datastore:operational/>, the configuration and status data of the current device is returned.
• xpath-filter: specifies a range to be queried in the configuration database in the form of an XPath. If this parameter is not specified, all configurations on the device are returned.
• subtree-filter: specifies a range to be queried in the configuration database in the form of a subtree. If this parameter is not specified, all configurations on the device are returned.

The following example shows how to query the task group configuration of the AAA feature in the <ietf-datastores:running/> configuration database. The queried group information is returned in an RPC reply message.
