Each command is listed, in detail, in the following sections.
config power_saving
Purpose
This command is used to configure the power saving for the system.
Syntax config power_saving {state [enable | disable] | length_detection [enable | disable]}
Description
By default, the power saving mode is enabled and the length detection mode is enabled. The
power saving length detection function applies to the ports with copper media.
The power is saved by the following mechanisms. When the port has no link partner, the port
automatically turns off and wakes up once a second to send a single link pulse. When the
port is turned off, a simple receive energy-detect circuit is continuously monitoring energy on
the cable. At the moment when energy is detected, the port turns on fully per IEEE
specification requirements. The power saving function is performed while no link is detected
and it will not affect the port capabilities while it is link up.
When the port is link up, for shorter cable, the power consumption can be reduced by
lowering the signal amplitude since the signal attenuation is proportional to the cable length.
The port will adjust the power based on cable length and still maintain error free applications
from both sides of the link. This mechanism will only be supported when the hardware
supports the cable diagnostics function.
Parameters state - (Optional) Configure the power saving state to enable or disable. The default value is
enable.
enable - Enable the power saving feature.
disable - Disable the power saving feature.
length_detection - Configure the length detection state to enable or disable. The default
value is enable.
enable - Enable the length detection feature.
disable - Disable the length detection feature.
Restrictions
Only Administrator and Operator-level users can issue this command.
