Stylistic conventions in this guide

To help you easily identify and understand certain types of information, this documentation uses the following stylistic conventions.

Using the solution examples

All examples in this documentation use only private IP addresses. When you set up the solutions we describe, you must use IP addresses suitable to your own network in place of our sample IP addresses.

Identifying new terms

When we first define a new term, the term is shown in bold italic text.

After you have completed the hardware configuration, using either the LCD panel or a console connected to the F5 appliance's serial port, you can configure the WANJet appliance using the browser-based utility, called the Web UI.

Identifying references to objects, names, and commands

We apply bold text to a variety of items to help you easily pick them out of a block of text. These items include web addresses, IP addresses, utility names, most controls in the Web UI, and portions of commands, such as variables and keywords.

For example, if the IP address of the appliance is, type in the web browser to login to the WANJet appliance.

Identifying references to other documents

We use italic text to denote a reference to another document.

For example, see the Quick Start Card for the F5 WANJet 200 or WANJet 400 appliance for information about installing F5 appliances.

Identifying command syntax

We show actual, complete commands in bold Courier text. Note that we do not include the corresponding screen prompt, unless the command is shown in a figure that depicts an entire command line screen. Table 1.1 explains additional special conventions used in command line syntax.
