Smart Licensing using Policy introduces a new paradigm for tracking license usage across your business. In earlier releases,
license authorization was forward- looking, binding licenses to a device until the next authorization request. Actual license
use during the proceeding reporting period is now sent to CSSM, allowing you to plan ongoing license requirements based on
historical usage data.
Each time a change in license usage is detected, the account policy defines how soon this should be reported to CSSM. Typically,
this means that CUBE must send a report at least every 90 days, although it is recommended that reports are sent more frequently.
CSSM acknowledges each submitted Resource Utilization Monitoring (RUM) report to ensure that the use is recorded reliably.
If the router does not receive an acknowledgment within the minimum reporting period, call processing may be disabled. Call
processing is resumed when a valid acknowledgment is received.
Submit the reports to CSSM directly or through a Smart Software Manager On-Prem server. The Cisco Smart Licensing Utility
(CSLU) application can also collect usage reports, providing more flexibility in managing your license usage. When a device
is not able to communicate directly with a licensing server, a signed usage report can be generated and manually uploaded
to CSSM. The CSSM generated acknowledgment must be uploaded to the device within the license reporting policy period to ensure
continued use.
Note
|
Cisco routers configured to process calls between voice ports and IP destinations will report the use of these sessions to
CSSM, where they are listed as a "CUBE v14 Voice Gateway Session". This usage is reported using the CUBE_T_VGW Smart entitlement tag, which may also be viewed using the show license all command and is provided for your information only. This reporting feature does not enforce voice port or IP sessions and
there would be no service interruption if the router is not registered to CSSM.
A quantity of purchased licenses equal to the number of reported sessions is automatically displayed in CSSM to avoid compliance
warnings. There is no requirement or option to purchase CUBE v14 Voice Gateway Session licenses.

Warning
|
When using any of the following Smart Licensing using Policy releases, CUBE shuts down if the router does not receive a report acknowledgment from CSSM before the acknowledgment deadline set by the
account policy: 17.3.2, 17.3.3, 17.3.4a, 17.6.1a, or any 17.4 or 17.5 release. CUBE does not shut down in this way with later releases.

License usage is calculated dynamically in the same way as earlier releases, with measurements recorded periodically based
on the periodicity timer. Measurements are stored locally until they are submitted to CSSM. This historical usage reporting
allows for more accurate aggregation of use across multiple devices over time. The minimum value for the periodicity timer
is increased to 8 hours.
The system records the changes every eight hours. It reports these changes to CSSM as soon as it detects any variations from
the previous value. However, note that this report is limited to a maximum frequency of once per 24 hours.
If the peak license usage for the current period is different by more or less than 25% of the previously reported value, it
is reported and periodicity interval is reset. Use of CUBE Standard Trunk and CUBE Enhanced Trunk licenses are monitored separately.
Note
|
Smart License Reservation (SLR) for CUBE licenses is not compatible with SLP. Even if a reservation is in place when upgrading, license use reporting will still be
required in accordance with the device policy. Reservations should therefore be returned immediately before or after upgrading
to a release that uses SLP.

Note

From Cisco IOS XE Bengaluru 17.6.1a onwards, calls that are forked using WebSockets are marked as consuming an Enhanced session license.
