Once you install and connect the hardware, the next step in the installation process is to turn the system on and run the First-Time Boot utility. The First-Time Boot utility defines the initial configuration settings required to install the BIG-IP into the network. You can run the First-Time Boot utility remotely from a web browser, or from an SSH or Telnet client, or you can run it directly from the console.
Before you connect to the unit, we recommend that you gather the list of information outlined in the following section. Note that the screens you see are tailored to the specific hardware and software configuration that you have. For example, if you have a stand-alone system, the First-Time Boot utility skips the redundant system screens.
Once you have gathered the information and are ready to run the utility, refer to Starting the First-Time Boot utility, on page 2-10.
The following sections provide detailed information about the settings that you define in the First-Time Boot utility.
Tip: A list is provided at the end of this section where you can fill in this information. See First-Time Boot utility configuration list, on page 2-8.
Select the type of keyboard you want use with the BIG-IP. The following options are available:
If you are configuring a BIG-IP Cache Controller, BIG-IP FireGuard, or BIG-IP LB Controller, you must now select one of these three as your product. When you have made your selection, the features supported by that product will be enabled.
Warning: Once you have configured your system based on one of the three product selections (BIG-IP Cache Controller, BIG-IP FireGuard, or BIG-IP LB Controller), changing the product selection will most likely invalidate that configuration. Therefore, you need to change and update your configuration after you have rebooted the system under the new product selection.
A root password allows you command line administrative access to the BIG-IP system. The password must contain a minimum of 6 characters, but no more than 32 characters. Passwords are case-sensitive, and we recommend that your password contain a combination of upper- and lower-case characters, as well as numbers and punctuation characters. Once you enter a password, the First-Time Boot utility prompts you to confirm your root password by typing it again. If the two passwords match, your password is immediately saved. If the two passwords do not match, the First-Time Boot utility provides an error message and prompts you to re-enter your password.
Warning: The root password and keyboard selection are the only settings that are saved immediately, rather than confirmed and committed at the end of the First-Time Boot utility process. You cannot change the root password until the First-Time Boot utility completes and you reboot the BIG-IP (see the BIG-IP Reference Guide, Monitoring and Administration). Note that you can change other system settings when the First-Time Boot utility prompts you to confirm your configuration settings.
The host name identifies the BIG-IP itself. Host names must be fully qualified domain names (FQDNs). The host portion of the name must start with a letter, and must be at least two characters.
If a BIG-IP does not have a predefined route for network traffic, the unit automatically sends traffic to the IP address that you define as the default route. Typically, a default route is set to a router's IP address.
There are two types of settings you need to define for redundant systems: unit IDs, and fail-over IP addresses.
The default unit ID number is 1. If this is the first unit in the redundant system, use the default. When you configure the second unit in the system, type 2. These unit IDs are used for active-active redundant configuration.
A fail-over IP address is the IP address of the unit which will take over if the current unit fails. Type in the IP address configured on the internal interface of the other BIG-IP in the redundant pair.
Configure media settings for each interface. The media type options depend on the network interface card included in your hardware configuration. The First-Time Boot utility prompts you with the settings that apply to the interface installed in the unit. The BIG-IP supports the following types:
Note: If you do not know the correct setting for your switch or hub, you can set the media type to auto and change it later when you know the correct setting. Check your switch or hub documentation for this information.
Warning: The configuration utility lists only the network interface devices that it detects during system boot. If the utility lists only one interface device, the network adapter may have come loose during shipping. Check the LED indicators on the network adapters to ensure that they are working and are connected.
You can create a new VLAN or use the default internal and external VLANs to create the BIG-IP configuration.
Determine whether you want to have security turned on for a VLAN, or off for the VLAN. Then, type the IP address settings for the VLAN. The IP address settings include:
We recommend that you set the floating self IP address as the default route for target devices, such as servers. The floating self IP address is owned by the active unit in an active/standby configuration.
Note: The IP address of the external VLAN is not the IP address of your site or sites. The IP addresses of the sites themselves are specified by the virtual IP addresses associated with each virtual server you configure.
After you configure the VLANs you want to use on the BIG-IP, you can assign interfaces to the VLANs. If you use the default internal and external VLANs, we recommend that you assign at least one interface to the external VLAN, and at least one interface to the internal VLAN. The external VLAN is the one on which the BIG-IP receives connection requests. The internal VLAN is typically the one that is connected to the network of servers, firewalls, or other equipment that the BIG-IP load balances.
After you assign interfaces to VLANs, you can choose one VLAN/IP address combination as the primary IP address to associate with the unit host name.
The BIG-IP web server provides the ability to set up remote web access on each VLAN. When you set up web access on a VLAN, you can connect to the web-based configuration utility through the VLAN. To enable web access, specify a fully qualified domain name (FQDN) for each VLAN. The BIG-IP web server configuration also requires that you define a user ID and password. If SSL is available, the configuration also generates authentication certificates.
The First-Time Boot utility guides you through a series of screens to set up remote web access.
Warning: If you ever change the IP addresses or host names on the BIG-IP interfaces, you must reconfigure the BIG-IP web server to reflect your new settings. You can run the re-configuration utility from the command line using the following command:
You can also add users to the existing password file, change a password for an existing user, or recreate the password file, without actually repeating the remote web server configuration process. For more information, see the BIG-IP Reference Guide, BIG-IP Base Configuration Tools.
Warning: If you have modified the remote web server configuration outside of the configuration utility, be aware that some changes may be lost when you run the reconfig_httpd utility. This utility overwrites the httpd.conf file and openssl.conf, but does not warn you before doing so.
Next, you need to specify your time zone. This ensures that the clock for the BIG-IP is set correctly, and that dates and times recorded in log files correspond to the time zone of the system administrator. Scroll through the list to find the time zone at your location. Note that one option may appear with multiple names. Select the time zone you want to use, and press the Enter key to continue.
You only need to complete this step if you want machines inside your BIG-IP managed network to use DNS servers outside of that network (for example, for reverse DNS lookup from a web server).
Specify the DNS name server and domain name for DNS proxy forwarding by the BIG-IP. For more information on DNS proxy forwarding see Configuring DNS on the BIG-IP, on page 3-8.
After you configure remote web access, the First-Time Boot utility prompts you to configure remote command line access. On most BIG-IP units, the first screen you see is the Configure SSH screen, which prompts you to type an IP address for SSH command line access. If SSH is not available, you are prompted to configure access through Telnet and FTP instead.
When you configure shell access, the First-Time Boot utility prompts you to create a support account for that method. You can use this support account to provide a support engineer access to the BIG-IP.
When the First-Time Boot utility prompts you to enter an IP address for administration, you can type a single IP address or a list of IP addresses, from which the BIG-IP will accept administrative connections (either remote shell connections, or connections to the web server on the BIG-IP). To specify a range of IP addresses, you can use the asterisk (*) as a wildcard character in the IP addresses.
The following example allows remote administration from all hosts on the 192.168.2.0/24 network:
Note: For administration purposes, you can connect to the BIG-IP floating self IP address, which always connects you to the active unit in an active/standby redundant system. To connect to a specific unit, connect directly to the IP address of that BIG-IP.
You can synchronize the time on the unit to a public time server by using Network Time Protocol (NTP). NTP is built on top of TCP/IP and assures accurate, local timekeeping with reference to clocks located on the Internet. This protocol is capable of synchronizing distributed clocks, within milliseconds, over long periods of time. If you choose to enable NTP, make sure UDP port 123 is open in both directions when the unit is behind a firewall.
If you have the 3-DNS module installed, you can configure NameSurfer to handle DNS zone file management for the unit. We strongly recommend that you configure NameSurfer to handle zone file management by selecting NameSurfer to be the master on the unit. If you select NameSurfer as the master, NameSurfer converts the DNS zone files on the unit and handles all changes and updates to these files. (You can access the NameSurfer application directly from the Configuration utility for the 3-DNS module).
The following list outlines the settings that the First-Time Boot utility prompts you to enter. For detailed information about these settings, see the previous section.
_____-_____-_____-_____ on VLAN __________________
Public clock server(s)_______________________________
User name _______________________________________
Set NameSurfer as master zone file_____________________
The First-Time Boot utility prompts you to enter the same information, whether you run the utility from a web browser, or from the command line. When the utility completes we recommend that you reboot the unit. This automatically removes the default IP address and root password provided specifically for the purposes of running the First-Time Boot utility remotely. The BIG-IP replaces the default IP address and root password with the password and IP addresses that you define while running the utility.
Before you can run the First-Time Boot utility from either the console or a serial terminal, you must first log in. Use the following default user name and password to log in.
After you log in, you can start the utility directly from the console or serial terminal by typing the command config. Once you complete the utility, we recommend that you reboot the BIG-IP.
Note: If you want to set up a terminal connection directly to the BIG-IP, see Using a serial terminal with the BIG-IP, on page 3-12.
You can run the First-Time Boot utility remotely only from a workstation that is on the same LAN as the unit. To allow remote connections for the First-Time Boot utility, the BIG-IP comes with two pre-defined IP addresses, and a pre-defined root password. The default root password is default, and the preferred default IP address is 192.168.1.245. If this IP address is unsuitable for your network, the BIG-IP uses an alternate IP address, 192.168.245.245. However, if you define an IP alias on an administrative workstation in the same IP network as the BIG-IP, the unit detects the network of the alias and uses the corresponding default IP address.
Once the utility finishes and the system reboots, these default IP addresses and root password are replaced by the information that you entered in the First-Time Boot utility.
You must set up an IP alias for your remote workstation before you turn on the unit and start the First-Time Boot utility. The remote workstation must be on the same IP network as the unit. If you add this alias prior to booting up the BIG-IP, the unit detects the alias and uses the corresponding address.
To set up an IP alias for the alternate IP address
The IP alias must be in the same network as the default IP address you want the BIG-IP to use. For example, on a UNIX workstation, you might create one of the following aliases:
ifconfig exp0 add 192.168.1.1
ifconfig exp0 add 192.168.245.1
Warning: On Microsoft Windows® or Windows NT® machines, you must use a static IP address, not DHCP. Within the network configuration, add an IP alias in the same network as the IP in use on the unit. For information about adding a static IP address to a Microsoft Windows operating system, please refer to your vendor's documentation.
After you configure an IP alias on the administrative workstation in the same IP network as the BIG-IP and you turn the system on, the BIG-IP sends ARPs on the internal VLAN to see if the preferred 192.168.1.245 IP address is in use. If the address is appropriate for your network and is currently available, the BIG-IP assigns it to the internal VLAN. You can immediately use it to connect to the unit and start the First-Time Boot utility.
If the alternate network is present on the LAN, 192.168.245.0/24, or if the node address 192.168.1.245 is in use, then the BIG-IP assigns the alternate IP address 192.168.245.245 to the internal VLAN instead.
When you start the utility from a web browser, you use the selected default IP address as the application URL.
To start the First-Time Boot utility in a web browser
You can run the command line version of the First-Time Boot utility from a remote SSH client or from a Telnet client.
