Using Additional Management Appliance Functionality


Understanding LED behavior

This section describes the LED behavior of the Enterprise Manager software, version 1.0 and later, on the Enterprise Manager 500 platform.

LED indicator functions

There are four types of LED indicators on the faceplate of each unit. Each LED indicator serves a specific function. The LED indicator functions are defined in Table 4.1 .

Table 4.1 LED indicator functions
Function
Description
Power
Reports the power status: on (green) or off (none). Note that units with the capacity for additional power supplies have a Power LED for each power supply bay.
Status
Reports the state of the system: Active, Standby, or undetermined
Activity
Reports storage device and network device activity
Alarm
Reports specific syslog alerts

LED indicator actions

The behavior, or action, of each of LED indicates the status of the system. The LED indicator actions are defined in Table 4.2 .

Table 4.2 LED indicator actions
Action
Description
off (none)
The LED is not lit and does not display any color.
solid
The LED is lit and does not blink.
blinking
The LED turns on and off at a regular frequency.
intermittent
The LED turns on and off with an irregular frequency and may sometimes appear solid.

Standard operating states

When the unit is in a standard operating state, the LEDs behave in a defined manner. The standard operating states are defined in Table 4.3 .

Alert conditions indicated by the LEDs

When there is an alert condition on the unit, the LEDs behave in a specific manner. The alert conditions are defined in Table 4.4 .

Note

Alerts that cause the indicators to change are defined in the /etc/alertd/alert.conf file on the Enterprise Manager system.

Specific alert conditions indicated by the LEDs

This section includes some specific conditions that not covered in the definition tables in the /etc/alertd/alert.conf. These conditions include:

  • Yellow intermittent Activity LED indicator
  • Green intermittent Activity LED indicator
  • Green solid Activity LED indicator

Yellow intermittent Activity LED indicator

While the kernel is loading, the Activity LED indicator will flash yellow intermittently when the disk is accessed. This condition is normal and occurs only during start up.

Green intermittent Activity LED indicator

When the Activity LED indicator flashes green intermittently, it indicates Ethernet interface activity, which includes, but is not limited to, inbound or outbound network traffic.

Yellow or green solid Status LED indicator

When the Status LED indicator is solid yellow or green, it indicates that the Enterprise Manager unit is in a Standby state (yellow) or an Active state (green).

Working with interfaces

You can perform configuration tasks such as displaying interface status and settings, setting the media type, and setting the duplex mode using the bigpipe command.

When using bigpipe, and a 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 4.1 shows an example of the output you see when you issue this command on an active/standby unit in active mode.

Figure 4.1 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
  1.1 UP  100 HD      0    213      0      0      0  74.2K      0       
  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 you can configure on the interfaces include media type and duplex mode, as shown in Table 4.5 .

Table 4.5 Attributes you can configure for an interface
Interface Properties
Description
Default
media
You may specify a media type or use auto for automatic detection.
auto
duplex
Use auto for automatic selection.
auto

Setting the media type

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

Warning

If the Enterprise Manager system is attempting to auto-negotiate interface settings with an interface that has the speed and duplex settings forced, you will experience severe performance degradation.

Use the following syntax to set the media type:

b interface <if name list> media <media type> | auto

The valid media types for this command are:

  • 10baseT <duplex>
  • 100baseTX <duplex>
  • 1000baseFX full
  • 1000baseT <duplex>
  • 1000baseSX full
  • 1000baseLX full |
  • 10GbaseSR full
  • 10GbaseLR full |
  • 10GbaseER full | auto

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

b interface <if name list> media show

Important

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

Setting the duplex mode

You can set duplex mode to full or half duplex. If the media type does not accept the duplex mode setting, an on-screen message indicates this. 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 /config/bigip_base.conf.

Use the following syntax to set the duplex mode:

b interface <if_name> duplex full | half
