The Modem Registrar user interface provides a flexible method for customizing DOCSIS configuration files. This chapter discusses the user interface, and explains how to start a session with Modem Registrar and how to manage administrators.
Modem Registrar provides a Web-based user interface that consists of a collection of pages, designed to enable you to perform a specific management or configuration task. Using these pages, you can do the following:
Online Help pages provide information about the fields and buttons on a user interface page. To open a Help page, click Help in the page's Modem Registrar Toolbar, shown in Figure 3-1.
Table 3-1 lists the menu pages available in the Modem Registrar user interface. For more information about the user interface pages, see "Modem Registrar User Interface Pages."
| User Interface Page | Description |
|---|---|
Login | Starts a session with Modem Registrar. |
Selects the functional area that you want to manage. | |
Selects the services that you want to manage. | |
Configure Option Sets | Selects the option sets that you want to manage. |
Configure TFTP Server | Selects the TFTP functional area you want to control or manage. |
Lists and deletes the administrators currently defined, and accesses the pages used to add and modify administrators. |
The Modem Registrar Toolbar (see Figure 3-1) appears on each of the user interface pages in the upper right-hand corner. The toolbar consists of the following buttons, although not all buttons are available for each page as indicated in the descriptions below:
The Modem Registrar Navigation Bar (see Figure 3-2) enables you to quickly navigate from one user interface page to another. The Navigation Bar appears just below the page title on each of the interface pages, except the Login and Main Menu pages.
The Navigation Bar consists of one or two rows of buttons, depending on the page. The top row of buttons provides the same selections available on the Main Menu page and corresponds to the four functional areas you may manage or configure. The buttons in this row are:
The bottom row of buttons provides access to the pages available from the selections in the top row. Selections displayed in red indicate the choices you are currently accessing. Selections displayed in green indicate the choices you can access.
For example, Figure 3-2 displays the option sets Navigation Bar. The buttons in the bottom row provide access to the pages available from the Option Sets button.
In addition to managing the TFTP server using the Web user interface (see "Managing the Cisco TFTP Server"), you can also use the command line interface (CLI) to manage the TFTP server. For more information, see the Cisco Network Registrar CLI Reference Guide.
To reload the TFTP server's memory, do the following:
Step 1 On the Main Menu page, click Configure TFTP Server.
Step 2 On the Configure TFTP Server page, click Control.
Step 3 On the Control TFTP Server page, click Reload.
The TFTP server stops and then immediately restarts with the changed LDAP configuration installed in the server's memory.
You are not notified if the server's memory was successfully updated. However, a message does appear if the reload operation failed.
The Modem Registrar user interface provides a flexible method for doing the following:
To simplify the configuration process, Cisco recommends that you define options for the general to the more specific option set scopings. First define options for the default option set (the most general option set) and then define option sets for more specific option sets, such as the CMTS and vendor option sets.
At a minimum, you must assign options to the default option set and create option sets for the CMTS and subnet option scopings.
You can choose to define the following optional option sets:
When using Modem Registrar for the first time, Cisco recommends that you follow these steps:
Step 1 Disable all existing TFTP services on the host on which you installed Cisco Network Registrar (CNR) version 3.0 (1)T or higher Technology (T) version.
Step 2 Create administrators (see "Creating and Managing Administrators" section).
Step 3 Configure the Cisco TFTP server using the Modem Registrar user interface (see "Managing the Cisco TFTP Server").
Step 4 Define services (see "Managing Services").
Step 5 Assign options to the default option set (see "Configuring the Default Option Set").
Step 6 Define the optional CMTS group option set, if desired, and the required CMTS and subnet option sets (see the online CMTS group option set Help pages, "Configuring CMTS Option Sets" and "Configuring Subnet Option Sets").
Step 7 Define the optional vendor and cable modem option sets, if desired (see "Configuring Vendor Option Sets" and the online cable modem option set Help pages).
Typically, the optional option sets are sparsely populated since they pertain to very specific cases within the installation.
As you define option sets, you must determine whether to actually assign option values to those sets. You may choose not to define options for some option sets. For example, you can create subnet option sets that model your physical installation, but that do not have any options assigned to them.
For more information on option set scopings, see the "Option Set Scopings" section.
The Cisco TFTP server provides standard TFTP services and dynamically creates customized configuration files for each DOCSIS cable modem. This server replaces all existing TFTP services running on your Solaris or Windows NT system. To prevent overlapping of services, you must disable all existing TFTP services on the host on which the Cisco Network Registrar's TFTP server is installed.
You can use the Login page (see Figure 3-3) to establish a session with Modem Registrar. This page provides fields for you to enter your username and password. If you are logging in to Modem Registrar for the first time, you can use the default username and password shown below. Subsequently, however, Cisco recommends that administrators log in using the username and password you create.
