Cisco offers Smart
Licensing, which enables you to monitor ISE software licenses and endpoint
license consumption easily and efficiently with a single token registration,
rather than invidiually importing separate licenses. Details of all Cisco
products and licenses that you have purchased are maintained in a centralized
database, called the Cisco Smart Software Manager (CSSM), where you can easily
track which endpoint licenses are available to you, and consumption statistics.
When a smart license
token is activated and registered from ISE, it monitors consumption of licenses
by each endpoint session per product license. Smart Licensing notifies the
administrator about license consumption by endpoint sessions from a simple
table layout in ISE. Smart Licensing reports the peak usage of each enabled
license to the centralized database daily. When licenses are available and not
consumed, the administrator is notified of available licenses and can continue
to monitor usage. When consumption exceeds the amount of licenses available, an
alarm is activated and the administrator is notified through alarms and
With Smart Licensing, you can also manage the
different license entitlements included through your Cisco Smart Account, such as Base,
Plus, Apex, or TACACS. From ISE, you can monitor basic consumption statistics per
license entitlement. From your CSSM account, you can also view additional information,
statistics and notifications, as well as make changes to your account and entitlements.

ISE takes internal samples of license consumption every 30 minutes, and compliancy and consumption is updated accordingly. To view this information in the Licenses table in ISE, you need only click Refresh. At 1:00 AM every day, ISE reports peak counts daily to the CSSM server (the centralized database) based on the Yesterday's Peak Count data that is also displayed in the Licenses table, for each enabled license. ISE communicates with the CSSM server by storing a local copy of the CSSM certificate, which is automatically re-authorized during the daily synchronization, and also when the user manually refreshes the Licenses table. Typically, certificates are valid for six months. If compliancy changes when synchronized with the CSSM server, the Last Authorization column of the Licenses table updates accordingly. In addition, when entitlements are no longer compliant, the number of days for which they are out of compliancy appears in the Days Out of Compliancy column. Non-compliancy is also indicated in Notifications at the top of the Licensing area, and on the ISE toolbar at the License Warning link. In addition to notifications, you can view Alarms. For more information, see Cisco ISE Alarms.

TACACS licenses are authorized when ISE communicates with the CSSM server, but they are not session-based and therefore no consumption count is associated with them in the Licenses table.
