Text structure and conventions
The text is broken down into chapters and subsections. Numbered subsections are shown in the table
of contents at the beginning. An index is included at the end of the document to aid with alphabetic-
al lookup of subjects.
Where a "See section" link (such as: see ) is provided in the main text this can be clicked to take the
reader directly to that reference.
Text that may appear in the user interface of the product is designated by being in Bold Case.
Where is term is being introduced for the first time or being stressed it may appear in a italics.
Where console interaction is shown in the main text outside of an example this will appear in a box
with a gray background:
gw-world:/>
Where a web address reference is shown in the text this will open the specified URL in a browser in
a new window when clicked (some systems may not allow this). For example: ht-
tp://www.dlink.com.

companying "CLI Reference Guide" documents all CLI commands).
