Software Compatibility
Network Registrar 3.0(1)T is compatible with the following:
• DHCP clients—All RFC 1954, 2132, and 2133 compliant DHCP and BOOTP clients
• DNS servers—Any DNS server compliant with RFC 2136 Dynamic DNS Updates and RFC
1995 and 1996 (IXFR and NOTIFY)
• LDAP servers—Any LDAP v2 or v3 server, including servers from Netscape, Sun
Microsystems, and Lucent Technologies
There is a known problem on Solaris that may cause the DHCP server to hang during initialization.
The problem is described by Sun RFE 4071167. You can encounter the deadlock in the Solaris name
resolver client by installing a linked set of patches from Sun, including 103663-08, and disabling
host name caching in nscd (to improve name resolver client performance), which is recommended
by Sun in RFE 1243174.
To avoid this problem, do one of the following:
• Do not install the linked patch set.
• Do not disable “nscd” host name caching.
• Install patch 103663-11 (Solaris 2.5.1) or 105755-01 (Solaris 2.6).

What’s New in This Release
The following sections describe the new features in Cisco Network Registrar Release 3.0(1)T and
Cisco Network Registrar Release 3.0T.
Cisco Network Registrar Release 3.0(1)T
Cisco Network Registrar Release 3.0(1)T offers these new features:
• DHCP lease query—A method for a uBR to discover the mapping between IP and MAC
addresses. This is necessary in some customer environments to prevent theft of service on the
cable network.
• Read-only user interface—A feature that allows a site to have one user interface in use with full
read/write privileges and a several interfaces in use with just read privileges.
• DNS force transfer—A method for a site to manually force an update on a secondary server when
the primary server has newer information.
• LDAP log and error messages—Messages that indicate progress in accessing an LDAP server.
This feature makes it easier to diagnose problems interfacing to LDAP.
• Improved server, GUI and CLI performance—A data structure enhancement that increases
processing speed and new lease generation when a large number of scopes are configured.
Cisco Network Registrar Release 3.0T
Cisco Network Registrar Release 3.0T offers these new features:
• Integration of the TFTP server into the CNR server framework
• Enhancements to the CNR user interfaces to support the TFTP server
• Enhancements to the CNR DHCP server in support of the TFTP server dynamic DOCSIS file
creation
• Enhancements and customizations to the CNR DHCP server in support of data-over-cable
deployments
• Improved performance
• Unique error code numbers on NT
• Support for Solaris 7

Upgrading From Previous Releases
Upgrading From Previous Releases
When you upgrade from a previous release of Network Registrar, you can choose to save your
database or overwrite it. If you overwrite your database, you lose all information about your zones,
scopes and leases.
Upgrading From CNR Release 1.x
To upgrade from any Network Registrar release numbered 1.x, you must first upgrade to release 2.0
before upgrading to release 3.0T or 3.0(1)T. Contact the Technical Assistance Center if you need
additional information.
Upgrading from CNR Release 2.x or 3.x Solaris
Warning The upgrade procedures for Solaris have changed from earlier revisions. Do not run the
Solaris pkgrm command before reviewing these instructions. The pkgrm command will delete
your data if you use it to remove or upgrade Network Registrar release 2.5.
To upgrade from Network Registrar release 2.x or 3.x, you must run the program upgrade_cnr in
the solaris subdirectory of the CD-ROM. If you use the standard configuration of the Solaris
automounter, this program will be located in the directory /cdrom/cnr_3_0_1_t/solaris/upgrade_cnr.
The upgrade program does the following:
• Backs up your existing database
• Uninstalls your current version of Network Registrar
• Installs the latest version of Network Registrar at the location where the previous version was
installed
Note You cannot use the upgrade program to install a new version of Network Registrar in a new
location. You cannot use the upgrade program to select options, such as Complete, Server, and GUI.
The upgrade program only upgrades the options that were previously installed.
To upgrade from Network Registrar 2.x or 3.x to Network Registrar 3.0(1)T on a Solaris server and
to preserve your database, do the following:
Step 1
Step 2
Login as root.
Run the /cdrom/cnr_3_0_1_t/solaris/upgrade_cnr program.
# /cdrom/cnr_3_0_1_t/solaris/upgrade_cnr
If you mount the CD-ROM manually, or have a non-standard automounter configuration,
or are using an unpacked electronic distribution of Network Registrar, replace
/cdrom/cnr_3_0_1_t with the directory on which the CD-ROM is mounted, or the
directory containing the unpacked electronic distribution.
Note You must run the script with an absolute path, as shown above. If you run it with
a relative path (for example, by typing cd /cdrom/cnr_3_0_1_t/solaris and then
./upgrade_cnr), it will not work.

Step 3
Follow the instructions on the screen.
This completes the procedure for upgrading from Network Registrar 2.x or 3.x to Network Registrar

Upgrading from CNR Release 2.x Windows NT Server
To upgrade from Network Registrar 2.x or 3.x to Network Registrar 3.0(1)T on a Windows NT
server and to preserve your database, do the following:
Step 1
Step 2
Run setup.exe.
Follow the instructions that appear on your screen.
Answer Yes to the question about upgrading your existing installation. This preserves the
data in your database.
To upgrade from Network Registrar 2.x or 3.x to Network Registrar 3.0(1)T on a Windows NT
server without preserving your database, do the following:
Step 1
Step 2
Run the uninstall program.
Perform an initial installation as described in the “Installing Network Registrar on
Windows” section on page 1-8 of the Network Registrar Getting Started Guide.
Note To non-interactively upgrade a previous release of Network Registrar, see the instructions in
the text file \i386\UPGRADE2.ISS on the Network Registrar CD.
