ON 1G copper ports. Energy-detect mode is always enabled on N4000 series
10G ports and cannot be disabled. An error message (Unable to set
energy-detect mode) will be displayed if the user attempts to configure

green-mode eee
Use the green-mode eee command in Interface Configuration mode to
enable EEE low power idle mode on an interface. The command enables both
send and receive sides of a link to disable some functionality for power savings
when lightly loaded. The transition to Low Power Idle mode does not change
the link status. Frames in transit are not dropped or corrupted in transition to
and from Low Power Idle mode.
On combo ports, eee mode can be enabled even if the port is using the fiber
interface. If enabled, eee mode is only active when the copper interface is
active.
Use the no form of the command to disable the feature.
