Licensing
Cisco Prime Network Registrar 11.3.1 supports both Smart Licensing and traditional licensing. However, it does not support the hybrid model, that is, you can use only one of the license types at a time. Cisco Prime Network Registrar 11.3.1 uses individual component licenses.
This allows you to purchase and install the following services individually or as a suite:
● DHCP services
● Authoritative DNS services
● Caching DNS services
If you need additional DNS Caching licenses, you should order them based on Server count since DNS Caching is a server-based license.
To install and manage DHCP, DNS, and Caching DNS licenses, you must deploy a regional server. The regional server, among other things, is used to install, count, and manage licensing for these components.
It licenses all services in the local clusters. Only the regional installation requires a license and can accept new licenses. Afterward, the regional server authorizes individual local clusters according to the available licenses.

Note:
● Licenses for Cisco Prime Network Registrar 10.x or earlier are not valid for Cisco Prime Network Registrar 11.x. You should have a new license for Cisco Prime Network Registrar 11.x.

● Smart Licensing is enabled by default in Cisco Prime Network Registrar 11.3. Cisco Prime Network Registrar 11.x regional, working in Smart License mode, does not support pre-11.0 local clusters. For more details, see the Using Smart Licensing section in Cisco Prime Network Registrar 11.3 Installation Guide

● Do not delete any individual licenses loaded from the file. If necessary, you may remove older versions of DNS and DHCP licenses after upgrading. However, retain older versions of CDNS licenses if the servers have not been upgraded.
