Change Setup Parameters provides access to all terminal configuration parameters. It is especially useful for setting configuration parameters when you have a few easily accessible terminals or when users set some or all configuration parameters themselves.

Procedures for configuring terminals using Change Setup Parameters are described in the System Administrator's Guide.

By default, you access Change Setup Parameters through the Console, after the NCD terminal has booted (Setup -> Change Setup Parameters). For other ways of starting and displaying local clients and information about disabling local clients, see the System Administrator's Guide.

Components of the Change Setup Parameters Window

Change Setup Parameters is composed of a series of hide boxes, which provide access to fields that correspond to remote configuration parameters.

Change Setup Parameters has a menu bar with a File menu and a Sections menu, a messages area, and several buttons.

• The File menu provides commands for writing values to and reading values from files and NVRAM:
  

  • Save to File-Specifies the name of a file to which all current parameter settings should be written. A popup dialog box presents the default filename or the last filename entered during this session.

  • Save to NVRAM-Saves settings to NVRAM as appropriate.

  • Read from File-Specifies a file from which all parameter settings should be read for display in the Change Setup Parameters window. Presents the default filename or the last filename entered during this session.

  • Read from NVRAM-Reads all NVRAM settings and displays them in the Change Setup Parameters window.

  • Restore Defaults-Loads parameter settings from the file defined in the config-default-file parameter. By default, the value in this parameter is the initial configuration file loaded at boot time.

  • Connect to New Unit-Presents a popup box requesting a terminal name and the config-read-only-password or config-read-write-password required for configuration data access. Displays the remote terminal's Change Setup Parameters window.

  • Close-Closes the Change Setup Parameters client.

• The Sections menu contains a listing of the Change Setup Parameters hide boxes, allowing you an alternative way to select one to open. You can also select to open or hide all hide boxes.
  

• The Messages area below the hide boxes displays Configuration daemon messages.
  

• The Auto Save File toggle below the Messages area enables or disables the Auto Save feature, described in the System Administrator's Guide and in Chapter 6, Terminal Configuration Methods.
  

• The four buttons along the bottom of the window allow you to commit changes to the current X session, to NVRAM, or to the configuration database:
  

  • Apply-Applies current changes to the current X session. Applies changes to NVRAM and to configuration files according to specifications set for the Auto Save feature. Parameters may take effect immediately after you click on Apply, at boot time, at session startup, or when a client is initialized. When you click on Apply, a message in the Messages area indicates when the change takes effect.

  • Restart-Removes changes that have not been applied.

  • Defaults-Loads parameter settings from the file defined in the config-default-file parameter. By default, the value in this parameter is the initial configuration file loaded at boot time.

  • Cancel-Removes changes that have not been applied and quits Change Setup Parameters (closes the window).

The following sections describe the contents of the Change Setup Parameters hide boxes.

The tables describing the hide box contents include a description of each field and the name of the corresponding remote configuration parameter. For the following information about parameters, see the alphabetical configuration parameter descriptions in the Remote Configuration Quick Reference:

• Permitted values
  

• SNMP variable names and paths
  

• When the parameter takes effect
  

• Whether the parameter is saved in NVRAM
  

The parameters in the Access Control hide box control access to the terminal configuration database and other terminal functions.
