Cisco Prime IP Express 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 IP Express 8.3.7, review the system requirements and licensing information available in the Cisco Prime IP Express 8.3.7 Installation Guide.

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

Cisco Prime IP Express DHCP, Authoritative DNS, and Caching DNS components are licensed and managed from the Cisco Prime IP Express 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 IP Express 8.2 and later.

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

The Cisco Prime IP Express 8.3.7 kit contains the following files and directories:

• Windows—Windows Server 2008 R2 installation kit.

• Docs—Pointer card, Bugs, and Enhancement List

The Cisco Prime IP Express also ships as a virtual appliance which includes all the functionality available in Cisco Prime IP Express along with the CentOS 7.6 operating system. The Cisco Prime IP Express 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 IP Express Virtual Appliance" section of the Cisco Prime IP Express 8.3.7 Installation Guide.

Cisco Prime IP Express introduced separate licenses for the components (System, DHCP, DNS, and CDNS) in release 8.3. For information on the Cisco Prime IP Express component-based license set, see the "License Files" section of the Cisco Prime IP Express 8.3.7 Installation Guide.

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

Cisco Prime IP Express currently offers the following sets of market segment based licenses:

• PNR

• PNR-ENT

• 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 Service Provider market segment, PNR-ENT offers features designed for the Enterprise 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 IP Express 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 IP Express 8.3 protocol servers interoperate with versions Cisco Prime Network Registrar 7.2 or later and Cisco Prime IP Express 8.2 and later except as noted below.

• Cisco Prime IP Express 8.2 and later DHCPv4 failover servers do not interoperate with versions prior to 8.2.

• The HA protocol version in Cisco Prime IP Express 8.2 and later will not communicate with versions earlier to Cisco Prime Network Registrar 8.0.

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

• Cisco Prime IP Express 8.3 DDNSv6 interoperates with Cisco Network Registrar 7.0 or later and Cisco Prime IP Express 8.2 and later DNS servers because of the use of the DHCID RRs (in place of TXT RRs for DDNSv6).
