Indicator LEDs

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

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.

Status LED

When the unit is in a standard operating state, the Status LED behaves in a defined manner.

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	The system is not under host computer control. This might be due to the host being halted or due to a software or hardware problem that interferes with the host's control of the LED.

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.

LED alert conditions

When there is an alert condition on the unit, the Alarm LED behaves in a specific manner.

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

Action	Description
System situation	Alarm LED behavior
Emergency	Red blinking
Alert or Critical	Red solid
Error	Yellow blinking

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.

Note: 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.
Add the following lines to the end of the file: 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. The front panel LEDs now indicate when a node is down.

Additional indicator LED status conditions

A few LED status conditions are not covered in the definition tables in the /etc/alertd/alert.conf file.

Yellow intermittent Status LED indicator

A yellow intermittent Status LED indicates that the unit is not under host computer control. This might be due to the host being halted or due to a software or hardware problem that interferes with the host’s control of the LED.

Green/Yellow solid Status LED indicator

When the Status LED indicator is solid yellow or green, it indicates that the system is in a Standby state (yellow) or an Active state (green). It displays solid green if the unit is Standalone or if it is the Active unit of a redundant system configuration. It displays yellow if the unit is the Standby member of a redundant system configuration.

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.

About managing interfaces

You can use tmsh or the Configuration utility to configure platform interfaces.

Viewing the status of a specific interface using tmsh

You can use tmsh to view the status of a specific interface on a platform.

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 current status of a specific interface. show interface <interface_key> The following is an example of the output you might see when you issue this command on interface 1.2: --------------------------------------------------------- Net::Interface Name Status Bits Bits Errs Errs Drops Drops Colli In Out In Out In Out sions --------------------------------------------------------- 1.2 up 191.4K 0 0 0 374 0 0

Viewing the status of all interfaces using tmsh

You can use tmsh to view the status of all interfaces on the platform.

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 current status of all interfaces. show interface The following is an example of the output you might see when you issue this command: ------------------------------------------------------------ Net::Interface Name Status Bits Bits Errs Errs Drops Drops Colli In Out In Out In Out sions ------------------------------------------------------------ 1.1 down 0 0 0 0 0 0 0 1.2 up 191.4K 0 0 0 374 0 0 1.3 down 0 0 0 0 0 0 0 1.4 up 22.5K 0 0 0 44 0 0 2.1 miss 0 0 0 0 0 0 0 2.2 miss 0 0 0 0 0 0 0 mgmt up 43.2G 160.0G 0 0 0 0 0

Viewing the status of all interfaces using the Configuration utility

You can use the Configuration utility to view the status of all interfaces on the platform.

On the Main tab, expand Network, and click Interfaces. This displays the list of available interfaces.
Click Statistics. 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 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 duplexsettings, 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: If you manually configure the platform to use specific speed and duplex settings on interfaces, Auto-MDI/MDIX functionality is disabled by default. When an interface is set manually, it functions as a data terminal equipment (DTE) port. This means that crossover cables are required to connect to other DTE devices (such as servers), and straight-through cables are required for connecting to data communications equipment (DCE) devices (for example, switches or routers). Be sure to use the correct cable type (straight-through or crossover) if you manually set interface speed and duplex settings.

Important: Starting with BIG-IP software versions 9.4.8 and 10.1.0, Auto-MDI/MDIX functionality is retained when you manually configure an interface to use specific speed and duplex settings. With these versions of the BIG-IP system, 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 using tmsh

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. show running-config interface <interface_key> media-capabilities
Important: In all Gigabit Ethernet modes, the only valid duplex mode is full duplex.
The following is an example of the output you might see when you issue this command on interface 1.3: net interface 1.3 { media-capabilities { none auto 10T-FD 10T-HD 100TX-FD 100TX-HD 1000T-FD 1000T-HD } }

Always-On Management

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

AOM consists of the host console shell (hostconsh) and the AOM Command Menu, which contains the options for AOM.

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

AOM Command Menu options

The AOM Command Menu provides Always-On Management options for the BIG-IP system.

Number/Letter	Option	Description
1	Connect to Host subsystem console	Exits the AOM Command Menu and returns to terminal emulation mode.
2	Reboot Host subsystem (sends reboot command)	Reboots the host subsystem. In this case, the Traffic Management Operating System (TMOS) is rebooted.
3	Reset Host subsystem (issues hardware reset--USE WITH CARE!)	Resets the host subsystem. In this case, TMOS is halted. Important: We do not recommend using this option under normal circumstances. It does not allow for graceful shutdown of the system.
4	Reset AOM subsystem (issues hardware reset--USE WITH CARE!)	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.
5	Power off/on Host subsystem (issues hardware shutdown--USE WITH CARE!)	Powers off the Host subsystem. In this case, TMOS is powered off. If the Host subsystem is already powered off, this option powers on the Host subsystem.
B	AOM baud rate configurator	Configures the baud speed for connecting to AOM using the serial console.
L	AOM subsystem login	Presents a logon prompt for the AOM subsystem. This subsystem cannot be configured by end users.
N	AOM network configurator	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.
P	AOM platform information	Displays information about the platform, including serial number and MAC address.
