Cisco SLR (Specific License Reservation)

Cisco SLR License (Specific License Reservation) applies in extremely secure networks to use smart licenses with no chance for connection to Cisco Smart Software Manager service (SSM). The Customer Smart Account must be entitled for License Reservation and the product instance is able to consume the reserved licenses without communicating usage information to SSM.

Registered devices with smart licenses share their data at regular intervals with Cisco Smart Software Manager (SSM) while devices that are deployed in an extremely secure network must not share the device information externally in any circumstances. License reservation is offered here as an on-request configuration for these devices.

License reservation contains partial or no functionality to certain Smart licensing features such as moving licenses between products, license usage, asset management and etc.

Cisco License Reservation

Specific License Reservation (SLR) allows reservation of specific licenses, including add-on licenses. First license reservation should be requested for the Smart Account. After response is received from the licensing support team, proceed with the next steps.

To reserve specific licenses for a device, first enter the generated request code from device in Cisco SSM along with the required licenses and their quantity and finally generate an authorization code. Enter the authorization code on the device to map the license to the Unique Device Identifier (UDI).

To reserve specific licenses for a stack configuration first generate a request code for each member in the stack then Generate individual authorization codes for each of the request codes and after that Register each member of the stack with the generated authorization code.

To reserve specific licenses for modular switches first generate request codes for the supervisor module and chassis module separately then Enter the request code in Cisco SSM and select the required licenses (Network license for the supervisor module and Cisco DNA license for the chassis module) and generate authorization codes. Eventually, register the supervisor module and the chassis module with the respective authorization codes.

For a Quad-Supervisor with RPR setup, generate authorization codes separately for the two chassis. Chassis 1 needs an authorization code with 2 Network licenses (for the two supervisor modules in Chassis 1) and 1 DNA license (for Chassis 1), and Chassis 2 needs another authorization code with 2 Network licenses (for the two supervisor modules in Chassis 2) and 1 DNA license (for Chassis 2)

To reserve specific licenses for a device, you need to first generate a request code from the device.  

Generating a Request Code from a Device 

First, license reservation should be enabled through the CLI with the following Command: 

Device(config)#license smart reservation enable 

After SLR is enabled, you must generate a request code from the device. 

Device# license smart reservation request [all |local]

Device Registration 

Finally, copy the generated authorization code into the device within the CLI command. 

Device# license smart reservation install file {flash:filename | tftp://filepath

After this procedure, all specific features that are included in your license would be activated on the device. 

Verifying the License Reservation 

To verify the license status after registration, use the show license reservation command: 

Device# show license reservation 

In the end, specified License Reservations can be used by any customer and on any smart account once Cisco approves them. Although, to avoid this, customers can use Permanent Licenses Reservation or Cisco PLR licenses which requires no approval from Cisco. Plus, it can register all product instances permanently and with full capabilities. 

Note: License reservation contains partial or no functionality to certain Smart licensing features such as moving licenses between products, license usage, asset management and etc.

Note: From IOS XE 17.3.2, SLR licenses would not be supported anymore, although applied licenses in earlier versions still would be honored.
