Introducing the IP Application Switch Platform


Working with the IP Application Switch platform

The IP Application SwitchTM platforms are powerful systems capable of managing traffic for any size of enterprise.

Externally, the IP Application Switch platforms look similar. However, there are internal differences and some external differences.

  • 1000 series
    This is the switch designed for the best performance at the price. This switch can manage all the capabilities of F5 Networks traffic management software. The 1000 series (Figure 1.1 ) provides the power of a 1 (Fiber Gigabit Ethernet) X 8 (10/100) switch, with SSL processing available as an additional add-on through the software license. For details, see Reviewing hardware specifications .
  • 2000 series
    The 2000 series switch has 2 (Fiber Gigabit Ethernet) X 16 (10/100) ports (Figure 1.2 ). The 2400 version of this switch incorporates the F5 Networks Packet Velocity ASICTM for accelerating Layer 4 (IP address and port) requests. All BIG-IP 2000 series switches include integrated SSL processing. For details, see Reviewing hardware specifications .
  • 5000 series
    The 5000 series switches are available with 4 (Fiber Gigabit Ethernet) X 24 (10/100) ports (Figure 1.3 ). The 5110 version of the switch includes 4 Copper Gigabit Ethernet interfaces instead of 4 Fiber Gigabit Ethernet interfaces. While all versions of the IP Application Switch accelerate Layer 7 traffic, the 5100 version of the switch is optimized to accelerate Layer 7 traffic. All 5000 series switches include dual processors and integrated SSL processing. For details, see Reviewing hardware specifications .

Getting started

There are several basic tasks you must complete to get the IP Application Switch platform installed and set up.

  • Review the hardware requirements.
  • Familiarize yourself with the IP Application Switch hardware.
  • Review the environmental requirements.
  • Connect the IP Application Switch to the network, and optionally connect the peripheral hardware.
  • Activate the license.

The IP Application Switch comes with the hardware that you need for installation and maintenance. However, you must also provide standard peripheral hardware, such as a keyboard or serial terminal, if you want to administer the IP Application Switch directly.

Components provided with the IP Application Switch

When you unpack the IP Application Switch, you should make sure that the following components, shown in Figure 1.4 , are included:

  • One power cable
  • Four rack-mounting screws
  • Documentation and Software CD


If you purchased a hardware-based redundant system, you also received one fail-over cable to connect the two IP Application Switch units together (network-based redundant systems do not require a fail-over cable).

Figure 1.4 Components included with the IP Application Switch

Peripheral hardware that you provide

For each IP Application Switch in the system, you need to provide the following peripheral hardware:

  • If you plan to use direct administrative access to the IP Application Switch, you need standard input/output hardware. This requires a serial terminal and a null modem cable. For serial terminal configuration information, refer to the BIG-IP Reference Guide, Chapter 3, Post-Setup Tasks in the section Using a serial terminal with the BIG-IP system.
  • If you want to use the default IP Application Switch configuration, you must have an administrative workstation on the same IP network as the IP Application Switch.
  • You also need network hubs, switches, or concentrators to connect to the IP Application Switch network interfaces. The devices you select must be compatible with the network interface cards installed in the IP Application Switch. The devices can support 10/100 Ethernet or Gigabit Ethernet.

    • Ethernet requires either a 10 Mbps or 100 Mbps hub or switch.
    • Gigabit Ethernet requires a compatible Gigabit Ethernet switch.

      If you plan on doing remote administration from your own PC workstation as most users do, we recommend that you have your workstation already in place. Keep in mind that the Setup utility prompts you to enter your workstation's IP address when you set up remote administrative access.

Familiarizing yourself with the IP Application Switch

The IP Application Switch is offered in several different hardware configurations. Before you begin to install the IP Application Switch, you may want to quickly review the following figures that illustrate the controls and ports on both the front and the back of an IP Application Switch.

Using the IP Application Switch hardware

This section describes the front and back layout of a IP Application Switch. Figure 1.5 illustrates the front of a IP Application Switch. On the front of the unit, you can turn the unit off and on, or you can reset the unit. You can also view the indicator lights for hard disk access.

Note


The interfaces on every IP Application Switch are labeled, so it should be clear what each port is, no matter which hardware configuration you have purchased.

Environmental requirements

Before you install the IP Application Switch, review the following guidelines to make sure that you are installing and using the IP Application Switch in the appropriate environment.

General guidelines

An IP Application Switch is an industrial network appliance, designed to be mounted in a standard 19-inch rack. To ensure safe installation and operation of the unit:

  • Install the rack according to the manufacturer's instructions, and check the rack for stability before placing equipment in it.
  • Build and position the rack so that once you install the IP Application Switch, the power supply and the vents on both the front and back of the unit remain unobstructed. The IP Application Switch must have adequate ventilation around the unit at all times.
  • Do not allow the air temperature in the room to exceed 40° C.
  • Do not plug the unit into a branch circuit shared by more electronic equipment than the circuit is designed to manage safely at one time.
  • Verify that the voltage selector is set appropriately before connecting the power cable to the unit.

Guidelines for DC-powered equipment

A DC-powered installation must meet the following requirements:

  • Install the unit using a 20 Amp external branch circuit protection device.
  • For permanently connected equipment, incorporate a readily accessible disconnect in the fixed wiring.
  • Use only copper conductors.

Installing and connecting the hardware

There are two basic tasks required to install the hardware. You simply need to install the IP Application Switch in a rack, and then connect the peripheral hardware and the interfaces.

Warning


Do not turn on an IP Application Switch until all peripheral hardware is connected to the unit.

To install the hardware in a rack

  1. Lift the unit into place. This requires more than one person.
  2. Secure the unit using the four rack-mounting screws that are provided.
    Figure 1.7 shows the orientation of the IP Application Switch and the mounting screws for installation in a standard 19" rack. Figure 1.8 shows the IP Application Switch installed in the rack.

    Figure 1.7 Platform orientation for rack mounting

    Figure 1.8 Platform installed in a 19" rack

To connect the cables and hardware for input/output

  1. Connect the hardware that you have chosen to use for input/output:

    If you are using a serial terminal as the console, connect the serial cable to the terminal serial port (number 1 in Figure 1.5 ).

  2. Connect the interfaces to the network from which the IP Application Switch processes connection requests. For more information about interfaces, see Interfaces .
  3. If you have a hardware-based redundant system, connect the fail-over cable to the fail-over port on each unit (number 2 in Figure 1.5 ).
  4. Connect the power cable to the IP Application Switch power in (number 2 in Figure 1.6 ), and then connect it to the power source.

Interfaces

This platform can have as few as one network interface. It is helpful to understand interface naming conventions before you perform configuration tasks such as displaying interface status and settings, setting the media type, and setting the duplex mode.

Interface naming conventions

By convention, the Ethernet interfaces on the platform take the name <s>.<p>, where s is the slot number of the NIC, and p is the port number on the NIC. As shown in Figure 1.9 , for the Application Switch, slot numbering is left-to-right and port numbering is top-to-bottom, as shown in Figure 1.9 . Note that slot 2 is used for the gigabit ports, and slot 3 for a dedicated administrative port.

Figure 1.9 IP Application Switch platform slot and port numbering

When a bigpipe command calls for a list of interfaces, the list may consist of one or more interfaces, with multiple interfaces separated by spaces. For example:

1.1 1.2 2.1 2.2

Displaying status and settings for interfaces

From the command line interface, use the following syntax to display the current status and the settings for all installed interfaces:

b interface show

Figure 1.10 shows an example of the output you see when you issue this command on an active/standby unit in active mode.

Figure 1.10 The bigpipe interface show command output


interface speed pkts pkts pkts pkts bits bits errors trunk STP
Mb/s in out drop coll in out

1.2 UP 100 HD 20 25 0 0 28.6K 33.9K 0
 

Use the following syntax to display the current status and the setting for a specific interface:

b interface <if_name> show

Media type and duplex mode

Properties that are configurable on the interfaces include media type and duplex mode, as shown in Table 1.2 .


 

Interface Properties

Description

media

You may specify a media type or use auto for automatic detection.

duplex

You may specify a full or half duplex mode, or use auto for automatic selection.

 

Setting the media type

You can set the media type to that of the interface, or to auto for auto-detection. If the media type is set to auto and the card does not support auto-detection, the default type for that interface is used, for example 100BaseTX.

Use the following syntax to set the media type:

b interface <if_name> media <media_type> | auto

(Default media type is auto.)

To view the valid media types for an interface, type the following command:

b interface <if_name> media show

Note


If the platform is inter-operating with an external switch, the media setting should match that of the switch.

Setting the duplex mode

You can set duplex mode to full or half duplex. If the media type does not allow duplex mode to be set, this is indicated by an onscreen message. If media type is set to auto, or if setting duplex mode is not supported for the interface, the duplex setting is not saved to bigip_base.conf.

Use the following syntax to set the duplex mode:

b interface <if_name> duplex full | half | auto

(Default mode is auto.)

Activating the license

Once the platform is installed in the rack and connected to the network, you need a valid license certificate to activate the software. To gain a license certificate, you need to provide two items to the license server: a registration key and a dossier.

The registration key is a 25-character string. In some cases, you may have received the key by email. If you received a CD, the number is on the back of the CD case. The registration key lets the license server know which F5 products you are entitled to license.

The dossier is obtained from the software, and is an encrypted list of key characteristics used to identify the platform

You can obtain a license certificate using one of the following methods:

  • Automatic license activation
    You perform automatic license activation from the command line, the License utility on an unlicensed unit, or from the web-based Configuration utility of an upgraded unit. The automatic method automatically retrieves and submits the dossier to the F5 license server, as well as installing the signed license certificate. In order for you to use this method, the unit must be installed on a network with Internet access.
  • Manual license activation
    You perform manual license activation from the License utility on an unlicensed unit, or from the web-based Configuration utility of an upgraded unit. With the manual method, you submit the dossier to, and retrieve the signed license file from, the F5 license server manually. In order for you to use this method, the administrative workstation must have Internet access.

    Note


    You can open the Configuration utility with Netscape® Navigator version 4.7x, or Microsoft® Internet Explorer version 5.0, 5.5 or 6.0.

Automatically activating a license

    See the BIG-IP Reference Guide, Chapter 2, Using the Setup Utility for full details and instructions. You can download the guide from the CD.

    Hardware acceleration

    The Packet Velocity ASIC optimizes application performance, and reduces application wait times. An ASIC is an Application Specific Integrated Circuit. The Packet Velocity ASIC is designed to accelerate Layer 4 decisions. Off-loading the Layer 4 decisions enables the BIG-IP system to increase performance and throughput for basic routing functions (Layer 4) and application switching (Layer 7). Figure 1.11 is an example of the Packet Velocity ASIC.

    Figure 1.11 The Packet Velocity ASIC

    Optional redundant power supply

    Several switch platforms are available with a redundant power supply. With this option, the standard power supply is replaced with a new unit which occupies the same space, but includes two independent power supply modules with separate connections to the power mains.

    The redundant power supply has no user controls. If one unit fails or is disconnected, the other unit takes over transparently.

    To report the status of the redundant power supply modules from the command line

    Type the following command to report the status of the redundant power supply modules:
