Peripheral hardware requirements

For each platform, you might need to provide additional peripheral hardware. If you plan to remotely administer the system, it would be helpful to have a workstation already connected to the same subnet as the management interface.

Type of hardware	Description
Network hubs, switches, or connectors to connect to the platform network interfaces	You must provide networking devices that are compatible with the network interface cards that are installed in the platform. You can use either 10/100/1000/10000-Gigabit or 40-Gigabit Ethernet switches.
External USB CD/DVD drive or USB flash drive	You can use any USB-certified CD/DVD mass storage device or a USB flash drive for installing upgrades and for system recovery. Note: External CD/DVD drives must be externally powered.
Serial console	You can remotely manage the platform by connecting to a serial console terminal server through the console port. Important: In the event that network access is impaired or not yet configured, the serial console might be the only way to access the unit. You should perform all installations and upgrades using the serial console, as these procedures require reboots, in which network connectivity is lost temporarily.
Management workstation on the same IP network as the platform	You can use the default platform configuration if you have a management workstation set up.

LCD panel

The LCD panel provides the ability to manage the unit without attaching a console or network cable.

Indicator LEDs

The behavior of each LED indicates the status of the system.

Status LED

The status LED indicate the operating state of the system.

State	Description
off/none	System is halted and powered down.
green solid	System is running in normal mode. Also indicates that the system is in an Active state of a device group.
yellow solid	System is running in an impaired mode. The condition is not considered to be significant enough to be considered an alarm condition. Also indicates that the system is the Standby member of a device group.
yellow blinking (with traffic)	The system is not under host computer control. This might be due to the host being halted or in EUD mode, or due to a software or hardware problem that interferes with the host's control of the LED.

Alarm LED

The alarm LED indicate system alarm conditions and the severity of the alarm condition.

There are five levels of messages.

Note: The alarm LED might continue to display until alerts are cleared using the LCD panel.

State	Description
off/none	Informational or no alarm conditions present. System is operating properly.
yellow solid	Warning (0). System may not be operating properly, but the condition is not severe or potentially damaging.
yellow blinking	Error (1). System is not operating properly, but the condition is not severe or potentially damaging.
red solid	Alert (2) or Critical (3). System is not operating properly, and the condition is potentially damaging.
red blinking	Emergency (4). System is not operating, and the condition is potentially damaging.

Power supply LEDs

The power supply LEDs indicate the operating state of the power supplies.

Power 1 state	Power 2 state	Description
green solid	green solid	Power supply is present and operating properly. Also indicates when the system in is power standby mode.
yellow solid	yellow solid	Power supply is present, but not operating properly.
off/none	off/none	No power supply present.

Indicator LED behavior

The indicator LEDs behave in a specific manner to indicate system or component status.

Behavior	Description
off (none)	LED is not lit and does not display any color.
solid	LED is lit and does not blink.
blinking	LED turns on and off at a regular frequency.
intermittent	LED turns on and off with an irregular frequency and might sometimes appear solid.

Defining custom alerts

The /etc/alertd/alert.conf and the /config/user_alert.conf files on the BIG-IP^® system define alerts that cause the indicators to change. The /etc/alertd/alert.conf file defines standard system alerts, and the /config/user_alert.conf file defines custom settings. You should edit only the /config/user_alert.conf file.

Open a command prompt on the system.
Change to the /config directory.
cd /config
Using a text editor, such as vi or Pico, open the /config/user_alert.conf file.

Edit the file, as needed.

For example, add these lines to the end of the file to create a custom alert in which the front panel LEDs indicate when a node is down:

alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_DOWN "Pool member (.*?):(.*?) monitor status down." 
{
  snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.10";
  lcdwarn description="Node down" priority="1"
}
alert BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_DOWN "Node (.*?) monitor status down." {
  snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.12";
  lcdwarn description="Node address down" priority="1"
}
alert BIGIP_MCPD_MCPDERR_POOL_MEMBER_MON_UP "Pool member (.*?):(.*?) monitor status up."
{
  snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.11"
}
alert BIGIP_MCPD_MCPDERR_NODE_ADDRESS_MON_UP "Node (.*?) monitor status up." 
{
  snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.13"
}

Save the file and exit the text editor.

Platform interfaces

Every platform includes multiple interfaces. The exact number of interfaces that are on the system depends on the platform type.

Each interface on the platform has a set of properties that you can configure, such as enabling or disabling the interface, setting the requested media type and duplex mode, and configuring flow control.

The Statistics screen for all interfaces opens.

About interface media type and duplex mode

All interfaces on the system default to auto-negotiate speed and full duplex settings. We recommend that you also configure any network equipment that you plan to use with the system to auto-negotiate speed and duplex settings. If you connect the system to network devices with forced speed and duplex settings, you must force the speed and duplex settings of the system to match the settings of the other network device.

Important: If the system is attempting to auto-negotiate interface settings with an interface that has the speed and duplex settings forced (that is, auto-negotiation is disabled), you will experience severe performance degradation. This applies to 10GbE and 40GbE interfaces.

By default, the media type on interfaces is set to automatically detect speed and duplex settings, but you can specify a media type as well. Use the following syntax to set the media type:

                     
tmsh modify net interface <interface_key> media <media_type> | auto

If the media type does not accept the duplex mode setting, a message appears. If media type is set to auto, or if the interface does not accept the duplex mode setting, the duplex setting is not saved to the /config/bigip_base.conf file.

Important: Auto-MDI/MDIX functionality is retained when you manually configure an interface to use specific speed and duplex settings. You can use either a straight-through cable or a crossover cable when media settings are forced, and you will be able to successfully link to either DTE or DCE devices.

Viewing valid media types for an interface

You can use tmsh to view the valid media types for an interface.

Note: This platform might not support all of the media type options that are available in tmsh.

Open the Traffic Management Shell (tmsh).
tmsh
Change to the network module.
net

The system prompt updates with the module name: user@bigip01(Active)(/Common)(tmos.net)#
Display the valid media types for a specific interface.
list interface <interface_key> media-capabilities

Important: In all Gigabit Ethernet modes, the only valid duplex mode is full duplex.

Always-On Management

The Always-On Management (AOM) subsystem enables you to manage the system remotely using serial console or SSH, even if the host is powered down. The AOM Command Menu operates independently of the Traffic Management Operating System^® (TMOS^®).

You can use the command menu to reset the unit if TMOS has locked up, or get access to TMOS directly, so that you can configure it from the command-line interface.

Note: The available functionality and options in AOM vary depending on the platform type.

AOM Command Menu options

The AOM Command Menu provides the AOM options for the platform. You can access the AOM Command Menu using either a serial console or SSH.

Note: The availability of menu options varies depending on the platform type.

Letter	Option	Description
B	Set console baud rate	Configures the baud speed for connecting to AOM using the serial console. Select from these options: 9600 19200 (default) 38400 57600 115200
I	Display platform information	Displays information about the AOM firmware and bootloader, chassis serial and part numbers, blade serial number, MAC address, and power status for the active console.
P	Power on/off host subsystem	Powers the host subsystem on or off.
R	Reset host subsystem	Resets the host subsystem with a hardware reset. Important: F5 Networks does not recommend using this option under typical circumstances. It does not allow for graceful shutdown of the system.
N	Configure AOM network	Runs the AOM network configuration utility. This utility enables you to reconfigure the IP address, netmask, and default gateway used by AOM. If you use this option while connected using SSH, your session will be disconnected as a part of the network configuration operation. Note: This option is not available when you are connected using SSH.
S	Configure SSH Server	Sets a session idle timeout (in seconds) for the AOM SSH server. Available values are 0 (no timeout; default value), or between 30 and 86400 (one day).
A	Reset AOM	Resets the AOM subsystem. In this case, the system is reset with a hardware reset. Important: We do not recommend using this option under normal circumstances. It does not allow for graceful shutdown of the system.
H	Host Console Capture Buffer	Buffers the last 4K bytes of console output from the host and saves it to a non-volatile storage location. Important: This option is hidden and disabled by default. It is intended to be used as a diagnostic tool by F5 technical support. When this option is enabled, then disabled, the buffer is cleared.
E	Display error report	Displays a list of latched events/errors or out-of-range sensors.
Q	Quit menu and return to console	Exits the AOM Command Menu and returns to terminal emulation mode.
