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 BIG-IP unit 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
You can perform configuration tasks such as displaying interface status and settings and setting the media type using
either the Traffic Management Shell (tmsh) or the bigpipe utility.
When using the bigpipe interface command or the tmsh interface command, you can either apply the command
to all interfaces or to a specific interface key.
Viewing the status of a specific interface
You can use bigpipe or tmsh to view the status of a specific interface on a platform.
From the command line interface, use the following syntax to display the current status of a specific interface:
