Cisco NX-OS gives you a 120-day grace period. This grace period starts or continues when you are evaluating a feature for which you have not installed a license.
The grace period stops if you disable a feature you are evaluating, but if you enable that feature again without a valid license, the grace period countdown continues from when it had stopped.
The grace period operates across all features in a license package. License packages can contain several features. If you disable a feature during the grace period and there are other features in that license package that are still enabled, the countdown does not stop for that license package. To suspend the grace period countdown for a license package, you must disable every feature in that license package. Use the show license usage license-name command to determine which applications to disable.

Application
-----------
PFM
-----------
The Cisco NX-OS license counter keeps track of all licenses on a switch. If you are evaluating a feature and the grace period has started, you will receive console messages, SNMP traps, system messages, and Call Home messages on a daily basis.
The frequency of these messages become hourly during the last seven days of the grace period.
Note |
You cannot modify the frequency of the grace period messages.
|
Caution |
After the final seven days of the grace period, the feature is turned off and your network traffic may be disrupted. Any future upgrade will enforce license requirements and the 120-day grace period.

Use the show license usage command to display grace period information for a switch.
