Description

“Enter” vs. “Type”

When the word “enter” is used in this guide, it means type

something, then press the Return or Enter key. Do not

press the Return or Enter key when an instruction simply

says “type.”

Conventions

11

“Syntax” vs. “Command”

When the word “syntax” is used in this guide, it indicates

that the general form of a command syntax is provided.

You must evaluate the syntax and supply the appropriate

port, path, value, address, or string. For example:

Enable RIPIP by using the following syntax:

SETDefault !<port> -RIPIP CONTrol =

Listen

In this example, you must supply a port number for

!<port>.

When the word “command” is used in this guide, it

indicates that all variables in the command have been

supplied and you can enter the command as shown in

text. For example:

Remove the IP address by entering the following

command:

SETDefault !0 -IP NETaddr = 0.0.0.0

For consistency and clarity, the full-form syntax (upper- and

lowercase letters) is provided. However, you can enter the

abbreviated form of a command by typing only the uppercase

portion and supplying the appropriate port, path, address,

value, and so on. You can enter the command in either upper-

or lowercase letters at the prompt.

Text represented as

This typeface

is used to represent commands that

you enter. For example:

SETDefault !0 -IP NETaddr = 0.0.0.0

Keys

When specific keys are referred

to in the text, they are

called out by their labels, such as “the Return key” or “the

Escape key,” or they may be shown as [Return] or [Esc].

If two or more keys are to be pressed simultaneously, the

keys are linked with a plus sign (+). For example:

Press [Ctrl]+[Alt]+[Del].
