2.1.4. The CLI
is described below), or remotely via an Ethernet interface using the Secure Shell (SSH) protocol
from an SSH client.
The CLI provides a comprehensive set of commands that allow the display and modification of
configuration data as well as allowing runtime data to be displayed and allowing system
maintenance tasks to be performed.
This section only provides a summary for using the CLI. For a complete reference for all CLI
commands, see the separate D-Link CLI Reference Guide.
The most often used CLI commands are:
• add - Adds an object such as an IP address or a rule to a NetDefendOS configuration.
• set - Sets some property of an object to a value. For example, this might be used to set the source
interface on an IP rule.
• show - Displays the current categories or display the values of a particular object.
• delete - Deletes a specific object.
CLI Command Structure
CLI commands usually begin with the structure: <command> <object_type> <object_name>. For
example, to display an IP address object called my_address, the command would be:
gw-world:/> show Address IP4Address my_address
The second part of the command specifies the object type and is necessary to identify what category
of object the object name refers to (consider that the same name might exist in two different
categories).
A command like add can also include object properties. To add a new IP4Address object with an IP
address of 10.49.02.01, the command would be:
gw-world:/> add IP4Address my_address Address=10.49.02.01
The object type can be optionally preceded by the object category. A category groups together a set
of types and mainly used with tab completion which is described below.
The CLI Command History
Just like the console in many versions of Microsoft Windows, the up and down arrow keys allow the
user to move through the list of commands in the CLI command history. For example, pressing the
up arrow key once will make the last command executed appear at the current CLI prompt. After a
Note: Category and Context
The term category is sometimes referred to as the context of an object.
Tip: Getting help about help
Typing the CLI command:
gw-world:/> help help
will give information about the help command itself.
