Introduction
Cisco Prime IP Express is comprised of these components:
■
■
Cisco offers these components as individually licensed applications or in a mix of suites.
In addition, for IP address management, you can deploy Cisco Prime Network Registrar IPAM, or you can integrate it with the DHCP and DNS components of Cisco Prime IP Express.
Before you Begin
Before you install Cisco Prime IP Express 8.3, review the system requirements and licensing information available in the Cisco Prime IP Express 8.3 Installation Guide .
Note: If you are migrating to Cisco Prime IP Express 8.3 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. Enterprise customers already using Cisco Prime Network Registrar can easily migrate to Cisco Prime IP Express using upgrade procedure. For more information, see the Installing and upgrading Cisco Prime IP Express section in Cisco Prime IP Express 8.3 Installation Guide .
Note: Licenses for Cisco Network Registrar 7.x or earlier are not valid for Cisco Prime IP Express 8.2 and later.
Cisco Prime Network Register IPAM is licensed separately from Cisco Prime IP Express DHCP, DNS, and Caching DNS. When installing IPAM, you will be asked to install as a separate process using a separate license key. To receive the IPAM license, you must purchase Cisco Prime Network Registrar IPAM, either individually, or as part of a Cisco Prime IP Express suite.
For more details about Licensing, see the License Files section in the Overview chapter of the Cisco Prime IP Express 8.3 Installation Guide.
The Cisco Prime IP Express 8.3 kit contains the following files and directories:

Market Segment Specific Licensing
Cisco Prime IP Express offers 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 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 three sets of market segment based licenses:
Note: If the licenses for both the 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.
PNR Licenses
The PNR license provides all the features available for the Cisco Prime Network Registrar release you install.
PNR-ENT Licenses
The Cisco Prime IP Express (PNR-ENT) license offers the following PNR features with the exception of (identified as not necessary for Enterprise market):

Note: Before you install Cisco Prime IP Express 8.3, review the system requirements and licensing in the Cisco Prime IP Express 8.3 Installation Guide.
PNR-SG Licenses
The PNR-SG license offers the following PNR features with the exception of (identified as not necessary for Smart Grid Implementations):
■

Interoperability
Cisco Prime IP Express 8.3 uses individual component licenses. This allows users to purchase and install DHCP services, Authoritative DNS and Caching DNS services, and IPAM services individually, or as a suite.
When you purchase the full set of Cisco Prime IP Express components, you receive a license package for IPAM, and a separate license for Cisco Prime IP Express DHCP and DNS components (Authoritative and Caching DNS).
Customers ordering the DDI 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 Cisco Prime Network Registrar IPAM license is installed separately and does not use the regional server.
The synchronization between version 8.3 and pre-8.3 local clusters must be done from an 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.

New Features and Enhancements
This section describes the features added in Cisco Prime IP Express 8.3.
■
■
■
■
■
■
Client-based DNS64 Prefixes
Cisco Prime IP Express DNS caching server supports DNS64, synthesizing AAAA (IPv6) records from A (IPv4) records, when an IPv6 client queries for AAAA records. DNS64 also handles reverse queries for the NAT64 prefixes. DNS64 with NAT64 provides access to the IPv4 internet and servers for hosts that have only IPv6 addresses. Cisco Prime IP Express 8.3, now supports up to 30 IPv6 prefixes in synthesis of IPv6 address for IPv4-only server instead of single prefix. The requests are matched to DNS64 prefixes using ACLs.
However, while configuring DNS64 on multiple Caching DNS servers, ensure that the same version of Cisco Prime Network Registrar is installed on all the servers.
Internationalized Domain Names
Cisco Prime IP Express 8.3 supports the full set of unicode characters to name DNS domains in the web UI, web-services (REST), and Java SDK with limited sort and search capabilities. The web UI displays domain names both in unicode and ASCII Compatibility Encoding format. The search and sort of unicode Domain names is possible only using the ASCII representation. The Cisco Prime IP Express CLI does not support unicode characters in this release.
Caching DNS and Authoritative DNS Server on the Same Operating System (DNS Hybrid)
In Cisco Prime IP Express 8.3, for small-sized DNS configurations, you can install the Caching DNS and Authoritative DNS servers on the same operating system, without the need for two separate virtual or physical machines.
The configuration is only recommended for smaller DNS configurations where the incoming traffic is low and a separate Caching DNS would not be required. When the Hybrid-mode configuration is enabled, the Caching DNS server detects the Authoritative DNS server on the same operating system and configures the in-memory exceptions to match the Authoritative DNS server zones. Caching DNS and Authoritative DNS needs different interfaces on the same operating system or have Authoritative DNS hidden on a separate port. Most management can be done via the Authoritative DNS configuration and reloads to Authoritative DNS causes Caching DNS to also reload automatically. For more information, see the Setting up Caching DNS and Authoritative DNS Server on Same Operating System section in Cisco Prime IP Express 8.3 DNS User Guide.
DNS Response Policy Zone (RPZ)
Cisco Prime IP Express 8.3 supports Response Policy Zones (RPZ). The DNS firewall rules can be set up for specially designated zones on the Authoritative DNS server. The RPZ and RR data combined with DNS Caching server resolver effectively creates a DNS firewall to prevent the misuse of the DNS server.
The RPZ firewall rules utilize both the Authoritative DNS and the Caching DNS servers to provide the RPZ functionality. The Authoritative DNS server stores the data for RPZ and the RPZ rules in the form of resource records (RRs). The Caching DNS server uses DNS Firewall configurations to access the rules and apply them to client queries and responses. For more information, see the DNS Response Policy Zone (RPZ) Firewall Rules section in Cisco Prime IP Express 8.3 DNS User Guide.
Cisco Prime IP Express REST APIs
The Representation State Transfer APIs (REST APIs) provide an alternative method to the Cisco Prime IP Express for provisioning selected functions. You can use the REST APIs to service a set of standard requests for all persisted (non-transient) classes in the service definition.
Either XML or JSON formatted objects, are specified as input or output parameters, as applicable. Request parameters are used to further qualify the client requests formed by URLs that identify the requested resource.
Miscellaneous Licensing Enhancements
In Cisco Prime IP Express 8.3, you can register a local cluster that is behind a NAT instance by initiating the registration from the local cluster. To register a local cluster that is spanned by a NAT instance, you must ensure that Cisco Prime IP Express 8.3 or later is installed on both the regional and local clusters. For more information, see the Registering a Local Cluster that is Behind a NAT section in the Cisco Prime IP Express 8.3 Administration Guide.
Resource Limit Alarms
Resource limit alarms enable you to monitor the Cisco Prime IP Express system resources and provides an indication when one or more product resources have entered potentially dangerous levels and requires attention.
Resource limit alarms are designed to convey the resource limit information in an organized and consolidated way. You can reset the predefined threshold levels for both critical and warning levels for each monitored resource. Cisco Prime IP Express reports the current status, the current value, and the peak value of the resources monitored in the web UI and CLI. The peak value is compared to the configured warning or critical limit for the resource limit alarm and the status of the resource limit alarm is displayed as OK, Warning or Critical.
The resource limit alarms are updated at regular intervals based on the polling interval configured. If SNMP traps are enabled for the resource limit alarms, Cisco Prime IP Express generates SNMP traps when the monitored resources exceed the critical or warning levels.
Cisco Prime IP Express displays the alarm in the web UI and CLI until the resulting condition no longer occurs and the peak value is reset.
Installing Protocol Servers without Super User Privilege
In Cisco Prime IP Express 8.3, you can now run Cisco Prime IP Express Local Server Agent as a non-root nradmin user on Linux. If you choose to run Cisco Prime IP Express for a non-root user, a user nradmin is created with the requisite privileges to run the Cisco Prime IP Express services. For more information, see the Installing Cisco Prime IP Express section in Cisco Prime IP Express 8.3 Installation Guide.
Supports CentOS 6.5
The operating system in Cisco Prime IP Express 8.3 Regional and Local virtual appliance is updated from CentOS 6.0 to CentOS 6.5. The Cisco Prime IP Express 8.3 OVAs are built using a new Packer process, unlike the previous versions built using VMWare Studio. Packer process is transparent and enables the resulting build process to adapt easily to other OS versions and to future products. The new packaging includes a change from an OVF contained in a.zip file, to a single.ova file. This simplifies deployment, since unpacking the.zip containing multiple files to get at the.ovf file, is avoided.
The process of configuring network in Cisco Prime IP Express 8.3 is script based where the user needs to run 'configurenetwork' command on completion of deployment. After booting up, if the system identifies the database and the code versions to be dissimilar, it directs to run a script to upgrade the database. At every login, the version of Cisco Prime IP Express running is displayed. For more information, see the System Requirements section in Cisco Prime IP Express 8.3 Installation Guide.
Note: To avoid the leap second issue in the existing installation, you need to apply the CentOS patch to your system.
