corresponding product instance for these licenses as well. Cisco may pre-install export-controlled licenses
when ordered with hardware purchase.
An example of an export-controlled license is the High Speed Encryption (HSECK9) license, which is
available on certain Cisco Routers.
License Duration
This refers to the duration or term for which a purchased license is valid. A given license may belong to any
one of the enforcement types mentioned above and be valid for the following durations:
• Perpetual: There is no expiration date for such a license.
Network Essentials and Network Advantage licenses are examples of perpetual licenses that are available
on Cisco Catalyst Access, Core, and Aggregation Switches.
• Subscription: The license is valid only until a certain date.
Digital Network Architecture (DNA) Essentials and DNA Advantage licenses are examples of subscription
licenses that are available on Cisco Catalyst Access, Core, and Aggregation Switches.
Authorization Code
The Smart Licensing Authorization Code (SLAC) allows activation and continued use of a license that is
export-controlled or enforced.
A SLAC is not required for any of the licenses available on Cisco Catalyst Access, Core, and Aggregation
Switches, but if you are upgrading from an earlier licensing model to Smart Licensing Using Policy, you may
have a Specific License Reservation (SLR) with its own authorization code. An SLR authorization code is
supported after upgrade to Smart Licensing Using Policy.
While existing SLRs are carried over after upgrade, you cannot request a new SLR in the Smart Licensing
Using Policy environment, because the notion of “reservation” does not apply. If you are in an air-gapped
network, the No Connectivity to CSSM and No CSLU topology applies instead.
Note
For more information about how the SLR authorization code is handled, see Upgrades, on page 105. If you
want to return an SLR authorization code, see Removing and Returning an Authorization Code, on page 154.
Policy
A policy provides the product instance with these reporting instructions:
• License usage report acknowledgement requirement (Reporting ACK required): The license usage report
is known as a RUM Report and the acknowledgement is referred to as an ACK (See RUM Report and
Report Acknowledgement). This is a yes or no value which specifies if the report for this product instance
requires CSSM acknowledgement or not. The default policy is always set to “yes”.
• First report requirement (days): The first report must be sent within the duration specified here.
If the value here is zero, no first report is required.
• Reporting frequency (days): The subsequent report must be sent within the duration specified here.
If the value here is zero, it means no further reporting is required unless there is a usage change.
