48.Power Saving Commands
The commands are used to configure the power saving mode.
If a port is not link up, the mode periodically repeats turning ON/OFF the
power feed to the port to save more power consumption than when the
power feed is always ON.
48.1. config power_saving

Description
This command is used to configure the power saving for the system. By default, the power
saving mode is enabled.
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.
