Preface

Audience
The target audience for this reference guide is:
• Administrators that are responsible for configuring and managing the D-Link Firewall.
• Administrators that are responsible for troubleshooting the D-Link Firewall.

knowledge in network security.
Notation
The following notation is used throughout this reference guide when specifying the options of a
command:
Angle brackets <name> or
-option=<description>
Square brackets [option] or
-option[=value]
Curly brackets {value1 | value2 |
value3}
Ellipsis ...
Example 1. Command option notation
One of the usages for the help command looks like this:
help -category={COMMANDS | TYPES} [<Topic>]
This means that help has an option called category which has two possible values which are COMMANDS and
TYPES. There is also an optional option called Topic which in this case is a search string used to specify what
help topic to display. Since the topic is optional, it is possible to exclude it when running the command.
Both of the following examples are valid for the usage described above:
gw-world:/> help -category=COMMANDS
gw-world:/> help -category=COMMANDS activate
The usage for the routes command is:
routes [-all] [-switched] [-flushl3cache[=<percent>]] [-num=<n>]
[-nonhost] [-tables] [-lookup=<ip address>] [-verbose]
[-setmtu=<mtu>] [-cacheinfo] [<table name>]...
None of the options of this command are mandatory. The flushl3cache option also has an optional value. This
is because that option has a default value, 100, which will be used if no value is specified.
The following two examples will yield the same result:
gw-world:/> routes -flushl3cache=100
gw-world:/> routes -flushl3cache
Used for specifying the name of an option or a description of
a value.
Used for specifying that an option or a value for an option is
optional and can be omitted.
Used for specifying the available values for an option.
Used for specifying that more than one value can be specified
for the option.
