YumaPro Server Features

YumaPro Server Features


Logging output integrated with SYSLOGStructured logging output can be sent to the SYSLOG deamon independently of the normal logging options.
Vendor-configurable messagesLogging messages can be customized with vendor-specific callback functions.
Facility, Class, Severity supportSYSLOG formatted and filtered message output is supported.
External SYSLOG API supportThe default SYSLOG service can be replaced with vendor-specific callback functions.


YANG-driven interfaceThe commands available are automatically populated based on the YANG modules loaded into yp-shell. The command line syntax is derived from the YANG syntax.
Config ModeThe config command is used to enter configuration mode. The YANG data nodes become the keywords and familiar CLI syntax is used to create, modify and delete configuration data.
Command RecallSeveral familiar command line recall mechanisms are supported:
history and recall commands to show recent command lines and recall a command line.
control-P (previous line) and Control-N (next line) to scroll through the history buffer.
The ! (bang character) to recall commands by line number or by matching the specified command string.
Context Sensitive EditingThe command completion text and available help text is context-sensitive, based on the YANG definitions, the current command mode or sub-mode, and the cursor position in the command line.
Command AliasesAliases are user-created commands that can be used to customize the command set and reduce typing.
The '?' Help KeyThe ‘?’ (question mark) key can be used to get context-sensitive help for the keyword(s) or value that is expected next within the current command line. The ‘tab’ key is used for short help text and the ‘?’ key is used for long help.

Role Based Access Control

Bypass ProtectionThe access control enforcement is integrated into the engine so no operations can bypass it and allow unauthorized access to configuration data.
IETF NACM SupportThe (standard) IETF NETCONF Access Control Model is supported.
Yuma NACM SupportThe (pre-standard) Yuma NETCONF Access Control Model is supported.
External ACM SupportAn external (vendor-specific) access control model can be selected instead of Yuma NACM or IETF NACM, and easily integrated into the netconfd-pro server through a structured API.


All CRUDX database operationsThe built-in transaction engine automatically handles all Create, Retrieval, Update, Delete, and eXecution operations for all NETCONF standards and all YANG modules.
Smart XPath CachingThe built-in XPath handler automatically detects which database nodes are referenced in any YANG must or when XPath expressions, allowing XPath results to be cached safely with no development effort or doctored YANG files.
YANG Defaults HandlingThe built-in transaction engine automatically handles all CRUDX operations correctly, even if default leafs and/or default non-presence containers are involved.
YANG featuresStandard YANG feature statements can be used to easily manage optional data model sections across multiple product platforms and product versions. Separate feature sets can be specified for each platform and release.
YANG extensionsStandard YANG extension statements and structured APIs can be used automatically process vendor-specific custom language statements.
Full Database lockingAutomatic support for standard all NETCONF database locking features.
Backup and Restore ManagementIntegrated backup and restore operations to simplify configuration management changes. Delete named backups with the delete-backup operation and view backup information in the YumaWorks monitoring extension to the standard ietf-netconf-monitoring module.
Transaction auditingConfigurable server transaction auditing with separate audit log.
Optimized Transaction Validation HandlingThe built-in transaction engine automatically detects which commit validation tests can safely be skipped because the database nodes involved in the test have not changed value. This includes all YANG XPath expressions (must, when), all instance tests (min-elements, max-elements, mandatory, unique, key), and all edit operations.
XPath Expression PruningThe built-in XPath handler automatically prunes false AND expressions and true OR expressions, which can greatly improve XPath validation speed.
YANG deviationsStandard YANG deviation statements can be used to easily manage data model diversity across multiple product platforms and product versions. Separate deviation files are automatically patched into the main module.
YANG user-defined typesStandard YANG typedef statements can be used to add any user-defined data types for reuse across multiple YANG modules.
YANG insert operationsAutomatic order-list insertion management through full support for the YANG insert operation extensions to NETCONF.
Partial Database lockingAutomatic support for standard all NETCONF partial-lock data sub-tree locking features.
Transaction managementAutomatic support for fully recoverable database edits, using a 3 phase transaction model, providing separate Validate, Apply, Commit and Rollback callback interfaces.
Confirmed-Commit HandlingFull automated support for the latest standard NETCONF confirmed-commit operations.

Data Retrieval Automation

Streamed or Bulk OutputThe netconfd-pro server is configurable so protocol messages can be streamed from data structures directly or buffered and sent in bulk transfer mode.
Subtree FilteringOptimized NETCONF sub-tree filtering with streamed output.
Time-stamp FilteringThe if-modified-since parameter is provided all NETCONF retrieval operations to minimize polling overhead. The will be empty if the running configuration has not changed since the specified date and time.
XPath FilteringFull XML Path Language (version 1.0) filtering with streamed output.
Event-type FilteringConfigurable event type filtering for notification delivery; only send notifications for desired event-types.
