address book entries, service definitions, IP rules and so on. Each configuration object has a
number of properties that constitute the values of the object.
Object Types
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 2.11. 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 which gives the option to edit or delete the object as well as modify the order of the
objects.
