Programmability

• YANG Data Models

• Pubd Restartability

The following programmability features are introduced in this release:

• YANG Data Models: For the list of Cisco IOS XE YANG models available with this release, navigate to: https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/1791.

  Revision statements embedded in the YANG files indicate if there has been a model revision. The README.md file in the same GitHub location highlights changes that have been made in the release.

  (Network Advantage)

• Pubd Restartability: The pubd process is restartable on all platforms in this release. Prior to this release, pubd was restartable only on certain platforms. On other platforms, to restart the pubd process, the whole device had to be restarted.

Smart Licensing Using Policy

• New mechanism to send data privacy related information

• Hostname support

The following Smart Licensing Using Policy features are introduced in this release:

• New mechanism to send data privacy related information: This information is no longer included in a RUM report.

  If data privacy is disabled (no license smart privacy { all | hostname | version} global configuration command), data privacy related information is sent in a separate sync message or offline file.

  Depending on the topology you have implemented, the product instance initiates the sending of this information in a separate message, or CSLU and SSM On-Prem initiates the retrieval of this information from the product instance, or this information is saved in the offline file that is generated when you enter the license smart save usage privileged EXEC command.

• Hostname support: Support for sending hostname information was introduced.

  If you configure a hostname on the product instance and disable the corresponding privacy setting (no license smart privacy hostname global configuration command), hostname information is sent from the product instance, in a separate sync message or offline file.

  Depending on the topology you have implemented, the hostname information is received by CSSM, and CSLU or SSM On-Prem. It is then displayed on the corresponding user interface.
