Layer 2 Switching Commands 492
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 no form of the
command to disable energy-detect mode on the interface(s).
Syntax
green-mode energy-detect
no green-mode energy-detect
Default Configuration
On N1100-ON, N1500, N2000, N2100-ON, N3000-ON, and N3100-ON
switches, energy-detect is enabled by default on the 1G copper interfaces.
Command Mode
Interface Configuration mode
User Guidelines
Use the green-mode energy-detect command in Interface Configuration
mode to enable energy on an interface. Energy detect powers off interfaces
that are not connected to another device.
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.
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 N1100-ON/N1500/N2000/N2100-ON/N3000-ON/N3100-ON
1G copper ports. An error message (Unable to set energy-detect
mode) will be displayed if the user attempts to configure energy-detect on a
10G port on a N1100-ON/N1500/N2000/N2100-ON/N3000-ON/N3100-ON
series switch.
