A configuration object has a well-defined type. The type defines the properties that are available for
the configuration object, as well as the constraints for those properties. For instance, the IP4Address
type is used for all configuration objects representing a named IPv4 address.
Object Organization
In the Web Interface the configuration objects are organized into a tree-like structure based on the
type of the object.
In the CLI, similar configuration object types are grouped together in a category. These categories
are different from the structure used in the Web Interface to allow quick access to the configuration
objects in the CLI. The IP4Address, IP4Group and EthernetAddress types are, for instance, grouped
in a category named Address, as they all represent different addresses. Consequently, Ethernet and
VLAN objects are all grouped in a category named Interface, as they are all interface objects. The
categories have actually no impact on the system configuration; they are merely provided as means
to simplify administration.
The following examples show how to manipulate objects.
Example 2.3. Listing Configuration Objects
To find out what configuration objects exist, you can retrieve a listing of the objects. This example shows how to
list all service objects.
Command-Line Interface
gw-world:/> show Service
A list of all services will be displayed, grouped by their respective type.
Web Interface
1. Go to Objects > Services
2. A web page listing all services will be presented.
A list contains the following basic elements:
• Add Button - Displays a dropdown menu when clicked. The menu will list all types of configuration items that
can be added to the list.
• Header - The header row displays the titles of the columns in the list. The tiny arrow images next to each title
can be used for sorting the list according to that column.
• Rows - Each row in the list corresponds to one configuration item. Most commonly, each row starts with the
name of the object (if the item has a name), followed by values for the columns in the list.
A single row in the list can be selected by clicking on the row on a spot where there is no hyperlink. The
background color of the row will turn dark blue. Right-clicking the row will display a menu where you can choose
to edit or delete the object as well as modify the order of the objects.
Example 2.4. Displaying a Configuration Object
The simplest operation on a configuration object is to show its contents, in other words the values of the object
properties. This example shows how to display the contents of a configuration object representing the telnet
service.
Command-Line Interface
gw-world:/> show Service ServiceTCPUDP telnet
