Cisco Prime IP Express 8.3.4 Release Notes
 
Interoperability
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.
Cisco Prime IP Express 8.2 and later DHCPv4 failover servers do not interoperate with the 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).
Cisco Prime IP Express 8.3 does not interoperate with Cisco Prime Network Registrar IPAM 8.1.1 or 8.1.2. An 
updated version of Cisco Prime Network Registrar IPAM is required to interoperate with Cisco Prime IP Express 8.3.

Resolved Bugs
In Cisco Prime IP Express release 8.3.4, several significant failover bugs related to DHCPv6 are fixed (see CSCuz89629, 
CSCuz93524, and CSCuz92787 in the cpnr_ipx_8_3_4_buglist.pdf file). We recommend that all customers using Cisco 
Prime IP Express releases 8.2 to 8.3.3 with failover (and especially those using DHCPv6), upgrade to release 8.3.4 as 
soon as possible.
