Layer 2 Switching Commands 450
green-mode energy-detect
This command enables a Dell EMC proprietary mode of power reduction on
ports that are not connected to another interface. Use the green-mode
energy-detect command in Interface Configuration mode to enable energy-
detect mode on an interface or all the interfaces. Energy-detect mode is
enabled by default on 1G copper interfaces and enabled by default on 10G
copper interfaces.
On combo ports, it is possible to configure energy-detect mode even if the
fiber port is enabled. If enabled, energy-detect mode will become active when
the copper port is used.
Use the no form of the command to disable energy-detect mode on the
interface(s).

User Guidelines
This command is available in Ethernet interface configuration mode. Cable
diagnostics (show copper-ports tdr command) may give misleading results if
green mode is enabled on the port. Disable green mode prior to running any
cable diagnostics. EEE and energy-detect modes are only supported on N4000
