Specific License Reservation (SLR) is a functionality that enables you to deploy a software license on a device without communicating usage information to Cisco. This functionality is especially used in highly secure networks, and it is supported on platforms that have Smart Licensing enabled.
SLR lets you reserve a license for your product instance from the CSSM. These reserved licenses need not be renewed or reauthorized unless there is a license usage change on the device.
License enforcement is a mechanism that prevents a feature from being used without first obtaining a license.The following enforcement mechanisms are available:
Hard enforcement: Hard enforcement is applicable only for enforced licenses . If you do not authorize the required licenses by installing the authorization code, the license cannot be used, and the feature is disabled.
Soft enforcement: When you do not authorize the required licenses by installing the authorization code, you can continue to use the license. The system displays an appropriate syslog message and the license status is “Not Authorized”.
 Note |
SLR is not enabled by default, and you must specifically request for this functionality. See How to Reserve Licenses |
For ASR1000 Series Routers with two Route Processors (RPs), do not change the state of the licenses on switching over to a new active RP.
The SLR authorization code file is valid only till you install the code. If there is an installation fialure, you must contact GLO to generate a new authorization code.
