Layer 2 Switching Commands 448
green-mode energy-detect
This command enables a Dell 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 disabled 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 commands) 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
Series 10G ports and on N1500/N2000/N3000 1G copper ports. Energy-detect
