1.2 User Interface
This chapter provides a general overview of the ONS 15200 Command Line Interface.
The following list describes the features of the ONS 15200 Command Line Interface:
The ONS 15200 Command Line Interface uses a UNIX-style, character-based user interface that allows users to communicate directly with the NCB module. The Command Line Interface provides commands that allows users to add, delete, and configure objects, alarms, and parameters.
The UNIX-style command line interpreter uses features specific to the ONS 15200 Command Line Interface. Table 1-1 lists the command line editing features.
Table 1-1: Command Line Editing Features
Many commands available in the ONS 15200 Command Line Interface have parameters that allow the user to configure specific aspects of a given command. These parameters are often required, but some are optional and can be omitted. Command parameter syntax follows rules that help the user identify which parameters are optional, which are required, which need to be repeated, and so on. These rules follow:
The ONS 15200 Command Line Interface has three operating modes. One mode grants read-and-write access to the parameters; the second mode grants read-only access; and the third grants access to the system commands. The command line prompt indicates the current mode.
Some commands, such as the configure command, automatically enter read-and-write mode. The prompt indicates the current mode, regardless of how the modes were entered or exited. The access privileges of the current user may prevent the user from entering read-and-write mode.
The network database has a structure similar to a file system. The data is structured hierarchically, with nodes and leaves. A leaf is a container for a value, and a node is a means to group related leaves (i.e., values) together in a tree structure. When many values on a certain level should be manipulated or monitored, it is necessary to set the current focus to a local top-node rather than the database top-node. Some commands, such as the create and configure commands, may also change the focus. A new focus also changes the command line prompt.
