Introduction


Getting started

Before you start configuring the BIG-IP Link Controller, we recommend that you browse this guide to find the solution that most closely addresses your needs. Briefly review the basic configuration tasks and the few pieces of information, such as IP addresses and host names, that you should gather in preparation for completing the tasks.

Once you find your solution and gather the necessary network information, turn to the Configuration Worksheet and Platform Guide for hardware installation instructions, and then return to this guide to follow the steps for setting up your chosen solution.

Choosing a configuration tool

The Link Controller offers both web-based and command line configuration tools, so that users can work in the environment with which they are most comfortable.

The Setup utility

All users need to use the Setup utility (formerly known as First-Time Boot utility). This utility walks you through the initial system set up. You can run the Setup utility from the command line, or from a web browser. The Setup utility prompts you to enter basic system information including a root password, and the IP addresses that will be assigned to the network interfaces. For more information, see Chapter 2, Using the Setup Utility, in the BIG-IP Reference Guide.

The Configuration utility

The Configuration utility is a web-based application that you use to configure and monitor the setup on the Link Controller. Once you complete the installation instructions described in this guide, you can use the Configuration utility to perform the configuration steps necessary for your chosen load balancing solution. In the Configuration utility, you can also monitor current system performance, and download administrative tools such as the SNMP MIB or the SSH client. The Configuration utility is best viewed with the following browsers: Netscape® Navigator version 4.7x, or Microsoft® Internet Explorer version 5.0, 5.5, or 6.0.

The bigpipe and bigtop command line utilities

The bigpipeTM utility is the command line counterpart to the Configuration utility. Using bigpipe commands, you can configure virtual servers, open ports to network traffic, and configure a wide variety of features. To monitor the Link Controller, you can use certain bigpipe commands, or you can use the bigtopTM utility, which provides real-time system monitoring. You can use the command line utilities directly on the Link Controller console, or you can run commands using a remote shell, such as the SSH client (encrypted communications only), or a Telnet client (if you are restricted by cryptography export laws). For detailed information about the command line syntax, see Appendix A in the BIG-IP Reference Guide.

Using the Administrator Kit

The Link Controller Administrator Kit provides all of the documentation you need to work with the BIG-IP Link Controller. The Link Controller includes the following printed documentation:

  • Configuration Worksheet
    This worksheet provides you with a place to plan the basic configuration for the BIG-IP system.

    The following guides are available in PDF format from the CD-ROM provided with the BIG-IP system. These guides are also available from the home screen when you first log in to the Configuration utility on the BIG-IP system.

  • Platform Guide
    This guide includes information about the BIG-IP unit. It also contains important environmental warnings.
  • BIG-IP Link Controller Solutions Guide
    This guide provides examples of common link load balancing solutions using the Link Controller. Before you begin configuring the Link Controller, we recommend that you browse this guide to find the load balancing solution that works best for you.
  • BIG-IP Reference Guide
    This guide provides detailed configuration information for all BIG-IP systems, including the Link Controller. It also provides syntax information for bigpipe commands, other command line utilities, configuration files, system utilities, and monitoring and administration information.

Stylistic conventions

To help you easily identify and understand important information, this section describes the stylistic conventions used in our documentation.

Using the solution examples

All examples in this documentation use only non-routable 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 addresses.

Identifying new terms

To help you identify sections where a term is defined, we show the term itself in bold italic text. For example, a virtual server is a specific combination of a virtual address and virtual port, associated with a content site that is managed by a Link Controller or other type of host server.

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, and portions of commands, such as variables and keywords. For example, with the bigpipe pool <pool_name> show command, you can specify a specific pool to show by specifying a pool name for the <pool_name> variable.

Identifying references to other documents

We use italic text to denote a reference to another document. In references where we provide the name of a book as well as a specific chapter or section in the book, we show the book name in bold, italic text, and the chapter/section name in italic text to help quickly differentiate the two. For example, you can find information about bigpipe commands in the BIG-IP Reference Guide, Appendix A, bigpipe Command Reference.

Identifying command syntax

We show 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. For example, the following commands show the configuration of the specified pool name:

bigpipe pool <pool_name> show

or

b pool <pool_name> show

Table Intro.1 explains additional special conventions used in command line syntax.
