Document conventions
The document conventions describe text formatting conventions, command syntax conventions, and important notice formats used in
Brocade technical documentation.
Notes, cautions, and warnings
Notes, cautions, and warning statements may be used in this document. They are listed in the order of increasing severity of potential
hazards.
NOTE
A Note provides a tip, guidance, or advice, emphasizes important information, or provides a reference to related information.
ATTENTION
An Attention statement indicates a stronger note, for example, to alert you when trac might be interrupted or the device might
reboot.
CAUTION
A Caution statement alerts you to situations that can be potentially hazardous to you or cause damage to hardware,
rmware, software, or data.
DANGER
A Danger statement indicates conditions or situations that can be potentially lethal or extremely hazardous to you. Safety
labels are also attached directly to products to warn of these conditions or situations.
Text formatting conventions
Text formatting conventions such as boldface, italic, or Courier font may be used to highlight specic words or phrases.
Format Description
bold text Identies command names.
Identies keywords and operands.
Identies the names of GUI elements.
Identies text to enter in the GUI.
italic text Identies emphasis.
Identies variables.
Identies document titles.
Courier font
Identies CLI output.
Brocade Fabric OS Administration Guide, 7.4.x
53-1003939-06 19
Format Description
Identies command syntax examples.
Command syntax conventions
Bold and italic text identify command syntax components. Delimiters and operators
dene groupings of parameters and their logical
relationships.
Convention Description
bold text Identies command names, keywords, and command options.
italic text Identies a variable.
value In Fibre Channel products, a xed value provided as input to a command option is printed in plain text, for
example, --show WWN.
[ ] Syntax components displayed within square brackets are optional.
Default responses to system prompts are enclosed in square brackets.
{ x | y | z } A choice of required parameters is enclosed in curly brackets separated by vertical bars. You must select
one of the options.
In Fibre Channel products, square brackets may be used instead for this purpose.
x | y A vertical bar separates mutually exclusive elements.
< > Nonprinting characters, for example, passwords, are enclosed in angle brackets.
... Repeat the previous element, for example, member[member...].
\ Indicates a “soft” line break in command examples. If a backslash separates two lines of a command
input, enter the entire command at the prompt without the backslash.
