Cisco Smart License
From Release 12.1 onwards, Unified SRST supports Smart Licensing, apart from the existing CSL licensing model. Smart Licensing is supported only on Cisco 4000 Series Integrated Services Router. Depending on the technology package available on the router, licenses such as UCK9 and Security are supported using Smart Licensing.
Smart Software Licensing is Cisco's new licensing model that gives you visibility into license ownership and consumption. Smart licenses can be managed by a cloud-based deployment model, namely Cisco Smart Software Manager (CSSM) or an on-prem software, Smart Software Manager satellite. Unified SRST is supported by both CSSM and satellite. Your access to the customer Smart Account residing on CSSM is authenticated using valid Cisco credentials. With the Smart Licensing support for Unified SRST, your device can register with CSSM or Cisco Smart Software Manager satellite. You can access your Licenses at the Cisco Software Central.
Unified SRST needs to register with CSSM or Cisco Smart Software Manager satellite to report license consumption. You can register Unified SRST to a Virtual Account within a Smart Account by generating a token ID from it, and pasting it to the underlying platform, Cisco 4000 Series Integrated Services Router. Once the token is generated, it can be used to register many other product instances in your network.
On the Unified SRST router, you need to ensure that the call home feature is not disabled. Also, Smart Licensing should be enabled at the router using the CLI command license smart enable. Use the no form of the command to disable Smart Licensing.
For more information on configuring Smart Licensing in your router, see Cisco 4000 Series ISRs Software Configuration Guide. For more information on configuring Call Home for your devices, see Configure Call Home. Once Smart Licensing is enabled, the router enters a 90-day evaluation period that persist until it registers to CSSM or the Cisco Smart Software Manager satellite.
You can register the router to CSSM or Cisco Smart Software Manager satellite with the token ID. To register the device (Unified SRST router) with CSSM or Cisco Smart Software Manager satellite, use the CLI command license smart register idtoken. For information on registering the device with CSSM, see Device Registration, Software Activation Configuration Guide, Cisco IOS Release 15M&T.
Upon successful registration, Unified SRST is in Registered status. As part of the registration process, the router sends an authorization request, indicating the number of phone endpoints defined by the max-pool, for SIP SRST, and max-ephone, for SCCP SRST. Based on the licenses in the Smart Account, CSSM or Cisco Smart Software Manager satellite responds with one of the defined statuses such as Authorized (using less than or equal to the number of licenses provisioned in CSSM or Cisco Smart Software Manager satellite) or Out-of-Compliance (using more than it has licenses for).
The license limit on Unified SRST is restricted by the maximum platform limit defined for the Unified SRST router (a cumulative sum of phones configured under max-pool and max-ephone). Hence, the license usage count cannot exceed the platform limit set for the Unified SRST router even when the cumulative sum of phones configured under max-pool and max-ephone exceeds the defined platform limit. For more details on the platform limits defined for Unified SRST, see Cisco Unified SRST/E-SRST 12.1 Supported Firmware, Platforms, Memory, and Voice Products.
CSSM or Smart Software Manager satellite reports license consumption submitted by the platform in its User Interface (UI), and subtracts it from the available licenses in the Virtual Account within the Smart Account. Unified SRST supports only one license entitlement to validate phones configured on Unified SRST.
SRST_EP —This license type supports all phones configured on Unified SRST.
Note The SRST_EP license count reflects the total phone count of both the ephones and pools that are configured in the Unified SRST irrespective of whether the phones are registered or not.
Unified SRST sends an authorization request when a license consumption changes or every 30 days to let CSSM or Cisco Smart Software Manager satellite know it's still available and communicating. The ID certificate issued to identify Unified SRST at time of registration is valid for one year, and is automatically renewed every six months.
Note If the router does not communicate with CSSM or Cisco Smart Software Manager satellite for a period of 90 days, the license authorization expires. When the license authorization expires, the devices registered on Unified SRST change status to Out of Compliance.
The license count is evaluated for the number of phones configured across the routers. The CSSM Licenses page reflects the total license count usage, the total number of licenses available for a type of license (Quantity), number of licenses currently used (In Use), and the number of unused or over-used licenses (Surplus/Shortage). If you do not have enough Cisco Smart licenses, you are in Out-of-Compliance state.
For example, consider a smart account in CSSM with 50 SRST_EP licenses. If the user has a registered Unified SRST with 20 phones configured, the CSSM licenses page reflects Quantity as 50, In Use as 20, and Surplus as 30.
