This section describes the LED behavior of the BIG-IP software, version 9.0
and later, on BIG-IP 1000, 2400, and 5100 platforms and the BIG-IP 1500, 3400, 6400, and 6800 platforms
Alerts that cause the indicators to change are defined in the /etc/alertd/alert.conf
and the /config/user_alert.conf
files on the BIG-IP system. You should only edit the /config/user_alert.conf
file to add new alerts. The /etc/alertd/alert.conf
file defines standard system alerts.
This section includes some specific conditions that are not covered in the
definition tables in the /etc/alertd/alert.conf
. These conditions include:
A yellow intermittent Activity LED indicates that host traffic is present.
Also, while the kernel is loading, the Activity LED indicator flashes yellow intermittently when the disk is accessed. This condition is normal and occurs only during boot up.
When the Activity LED indicator flashes green intermittently, it indicates
Ethernet traffic leaving the switch subsystem and going to the CPU subsystem. Because internal traffic may cause this indicator to be active, you may see the Activity indicator flicker green even though there is no external client/server traffic.
You can perform configuration tasks such as displaying interface status and
settings, setting the media type, and setting the duplex mode using the bigpipe
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:
shows an example of the output you see when you issue this command on an active/standby unit in active mode.
All interfaces on the BIG-IP system default to auto-negotiate speed and
duplex settings. We recommend that you configure any network equipment that you plan to use with the BIG-IP system to auto-negotiate speed and duplex settings. If you connect the BIG-IP system to network devices with forced speed and duplex settings, you must force the speed and duplex settings of the BIG-IP system to match the settings of the other network device.
You can set duplex mode to full or half duplex. If the media type does not
accept the duplex mode setting, an unscrewing 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
The Packet Velocity ASIC®
2 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).
