The Cisco Subscriber Registration Center (CSRC) software packages operate with the following software components:
You must precisely install and configure each software package to ensure the proper operation of CSRC. If you already have the required version of a component installed, you do not need to re-install it.
This chapter provides an installation worksheet to help you enter consistent values as you install the software packages, including the CSRC packages. This chapter also provides information to help you design your data center and it provides an overview of the installation process.
To install CSRC and the independent software packages that CSRC requires, you will need the following:
During the installation of CSRC and the various software packages CSRC requires, the installation utilities sometimes require you to enter values that pertain to the installation of a previously installed component (for example, the LDAP administrative password entered during the directory server installation). The "CSRC Installation Worksheet" (see Figure 2-1) is designed to help you remember the values you enter and to provide consistent parameter information.
Before you begin installing CSRC, review the parameters listed on the "CSRC Installation Worksheet" in the Parameter column. These are the parameters for which multiple installer programs ask you to enter values. If you know a parameter value, enter it in the corresponding numbered box in the Value column.
Default values, if available, are listed in brackets following the prompt. For example:
Enter the directory server administrator ID [admin]:
As you install each software package, refer to the appropriate box on the "CSRC Installation Worksheet" when the installer prompts you for a specific parameter value. If a value is not specified explicitly on the "CSRC Installation Worksheet" (see Figure 2-1), then enter that value at the installer's prompt and in the appropriate box on the "CSRC Installation Worksheet" to help you remember it.
 | Tips
Make a photocopy of the "CSRC Installation Worksheet" and enter the parameter values on the photocopy.

The architecture of CSRC provides for flexibility in designing your data center. CSRC requires that you install the following software packages:
You can install the software packages on multiple hosts with different operating systems. Table 2-1 lists the major server components of CSRC and the software components that you must install for each server component.
| Server Component | Required Software |
|---|---|
Directory Server | Directory Server CSCOcsrcd |
Cisco Network Registrar Server (CSRC DNS services) | Cisco Network Registrar |
Cisco Network Registrar Server (Standard DNS) | Cisco Network Registrar |
Cisco Network Registrar Server (DHCP services) | Cisco Network Registrar |
Cisco Network Registrar Server (Time-of-day and TFTP services) | Cisco Network Registrar CSCOcsrcn |
CSRC Web Interface (Modem Registrar and User Registrar) | CSCOcsrcw CNR user interface |
CSRC Command Line Utilities | CSCOcsrcu CNR user interface |
Table 2-2 lists the major components of CSRC and provides three example configurations.
| Server Function | Example 1: Four Hosts | Example 2: Five Hosts | Example 3: One Host |
|---|---|---|---|
| Directory Server
Provides directory services. | Host 1 | Host 1 | Host 1 |
| Cisco Network Registrar Server (CSRC DNS services)
Provides DNS services for the User Registrar component of CSRC. Provides a "dummy" root zone that resolves all names to the CSRC User Registrar server. | Host 2 | Host 2 | Host 1 |
| Standard DNS Services
A place holder for "standard" DNS services, which are not part of the CSRC installation. If you use CNR to provide DNS, Cisco recommends a three-server configuration in the RDC: two primary servers (forward and reverse) and one secondary server that accepts resolver requests. | |||
| Cisco Network Registrar Server (DHCP services) | Host 3 | Host 2 | Host 1 |
| Cisco Network Registrar Server (TOD and TFTP services)
CNR time-of-day (TOD) and trivial file transfer protocol (TFTP) servers typically share a single host. | Host 3 | Host 3 | Host 1 |
| CSRC Web user interface
Provides the core CSRC services, such as User Registrar. You must install the software components required for this server on one host. | Host 2 | Host 4 | Host 1 |
| CSRC command line utilities
Cisco recommends that you install these utilities on the same host as the CSRC Web user interface. | Host 2 | Host 4 | Host 1 |
| Access Registrar (AR) RADIUS Server
Required for installations in a telco-return cable modem environment. You cannot install AR on the same host as CNR. This guide does not discuss the installation and use of AR. | Host 4 | Host 5 | Not Applicable |
CSRC is not a standalone, off-the-shelf product, but instead depends heavily on the proper installation and configuration of other applications and utilities. For this reason, Cisco recommends that you first review the installation process summary to familiarize yourself with the overall installation process.
For more detailed information, see "Installing the Software Packages."
The CSRC installation process consists of the following steps:
Step 1 Install Cisco Network Registrar version 3.0(1)T or higher version.
Step 2 Install an LDAP version 3 compliant directory server.
Step 3 Install the CSRC software packages for Solaris.
Step 4 Start the CSRC servers and the TFTP server.
Step 5 Verify the installation.
Step 6 Configure CSRC into your cable network.
