Cisco Prime Network Registrar is comprised of these components:

• An Authoritative Domain Name System (DNS) protocol service

• A Caching DNS (CDNS) service

• A Dynamic Host Configuration Protocol (DHCP) service

Cisco offers these components as individually licensed applications or in a mix of suites.

Before you install Cisco Prime Network Registrar 8.3.7, review the system requirements and licensing information available in the Cisco Prime Network Registrar 8.3.7 Installation Guide.

Note	If you are migrating to Cisco Prime Network Registrar 8.3.7 from an earlier version of Cisco Prime Network Registrar, you must review the release notes for the releases that occurred in between, to fully understand all the changes.

Cisco Prime Network Registrar DHCP, Authoritative DNS, and Caching DNS components are licensed and managed from the Cisco Prime Network Registrar regional server. All services in the local clusters are licensed through the regional cluster. Only a regional install requires a license file and only the regional server accepts new license files. Then the regional server can authorize individual local clusters, based on available licenses.

Note	Licenses of Cisco Network Registrar 7.x or earlier are not valid for Cisco Prime Network Registrar 8.x.

For more details about Licensing, see the "License Files" section of the Cisco Prime Network Registrar 8.3.7 Installation Guide.

The Cisco Prime Network Registrar 8.3.7 kit contains the following files and directories:

• Solaris—Solaris 10 installation kit

  Note	The last date of support on Solaris for all 8.x PNR releases (that is, 8.1, 8.2, and 8.3) was July 2017. However, Solaris is supported in Cisco Prime Network Registrar 8.3.7 to meet the customer requirements.

• Linux—CentOS 6.5/Red Hat Linux ES 6.5 and later installation kit

  Note	Cisco Prime Network Registrar 8.3.7 supports 64-bit Linux installations only.

• Windows—Windows Server 2008 R2 installation kit.

• Docs—Pointer card, Bugs, and Enhancement List

The Cisco Prime Network Registrar also ships as a virtual appliance which includes all the functionality available in Cisco Prime Network Registrar along with the CentOS 7.6 operating system. The Cisco Prime Network Registrar virtual appliance is supported on VMware ESXi 5.5 or later platforms, and CentOS/RHEL 7.6 KVM Hypervisor. For more details, see the "Cisco Prime Network Registrar Virtual Appliance" section of the Cisco Prime Network Registrar 8.3.7 Installation Guide.

Cisco Prime Network Registrar introduced separate licenses for the components (System, DHCP, DNS, and CDNS) in release 8.0. For information on the Cisco Prime Network Registrar component-based license set, see the "License Files" section of the Cisco Prime Network Registrar 8.3.7 Installation Guide.

Cisco Prime Network Registrar license types are offered specific to market segments. Market-specific licensing generates license keys for use by market segments, that is, Service Provider, Smart Grid, and others. Cisco Prime Network Registrar features are enabled based on the market segment specific license you choose.

Cisco Prime Network Registrar currently offers the following sets of market segment based licenses:

• PNR

• PNR-SG

Note	If the licenses for both market segments are installed, then only the PNR license will be active.

The PNR license offers features designed for the Enterprise and Service Provider market segment, whereas the PNR-SG license offers features designed for the Smart Grid market segment.

The regional server which uses the PNR-SG license can be converted to PNR by installing the PNR license. Local cluster licenses will be converted automatically at the next compliance check, or can be manually updated by resynchronizing the local cluster.

For a given market segment license, only the counts from corresponding market segment license will apply.

For example, if the PNR count license is applied when the PNR-SG base license is active, the Right to Use count will not be updated. If the PNR-SG count license is applied when the PNR base license is active, the Right to Use count will not be updated.

Cisco Prime Network Registrar 8.3.7 requires 8.x licenses for DHCP and DNS authoritative services. These licenses are applied system-wide and support both 8.3.7 local clusters and existing 8.x local clusters. Cisco Prime Network Registrar 8.3.7 supports earlier versions of the DNS caching license for existing 8.x local clusters. 8.3.7 local clusters require 8.x licenses. If you are using the Cisco Prime Network Registrar 8.x platform, you can purchase upgrade licenses. Versions released prior to Cisco Prime Network Registrar 8.x are not eligible for upgrade licensing and are directed to the Cisco Prime Network Registrar 8.x full license.

Cisco Prime Network Registrar 8.3 uses individual component licenses. This allows users to purchase and install DHCP services, Authoritative DNS services, and Caching DNS services individually, or as a suite.

Customers ordering the DD bundle would obtain a quantity one of the Caching DNS when they acquire the DNS authoritative license. If they need additional DNS caching licenses they are ordered based on Server count since DNS caching is a server based license.

To install and manage DHCP, DNS, and Caching DNS licenses, you must establish a regional server. The regional server is used to install, count, and manage licensing for these components.

The synchronization between version 8.3 and pre-8.3 local clusters must be done from a 8.3 regional cluster. Cisco Prime Network Registrar 8.3 protocol servers interoperate with versions 7.2 or later except as noted below.

• Cisco Prime Network Registrar 8.2 and later DHCPv4 failover servers do not interoperate with versions prior to 8.2. Therefore, if you are upgrading from 8.1 and earlier to 8.2 and later, you must upgrade both failover partners. Also, any firewalls need to be updated to allow TCP traffic on the failover port (547). And, for 8.2 and later failover extends to DHCPv6.

• The HA protocol version has been updated in Cisco Prime Network Registrar 8.0 and communications with earlier versions is not supported.

• By the nature of the EDNS0 protocol, Cisco Prime Network Registrar 8.3 DNS servers interoperate with earlier versions of Cisco Prime Network Registrar DNS (and third party DNS vendors). EDNS0 defines the interoperability with DNS servers that do not support EDNS0. Cisco Prime Network Registrar 8.3 DNS adheres to the RFC and consequently interoperates with earlier versions of Cisco Prime Network Registrar.

• Cisco Prime Network Registrar 8.3 DDNSv6 interoperates with Cisco Network Registrar 7.0 and later DNS servers because of the use of the DHCID RRs (in place of TXT RRs for DDNSv6).
