Smart Licensing Using Policy
|
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.
