Green Ethernet Commands

Dell EMC Networking N1100-ON/N1500/N2000/N2100-
ON/N3000/N3100-ON/N4000 Series Switches
Dell EMC Networking switches support various Green Ethernet modes, i.e.,
power saving modes, namely:
Energy-Detect Mode
Energy Efficient Ethernet
These modes can enable significant operational cost reductions through
direct power savings and reducing cooling costs. Green mode commands are
only valid for copper physical interfaces.
Energy-Detect Mode
With this mode enabled, when the port link is down the PHY automatically
goes down for short periods of time and then wakes up periodically to check
for link pulses. This reduces power consumption when no link partner is
present. This feature is currently available only on GE copper ports.
Energy Efficient Ethernet
Energy Efficient Ethernet (EEE) combines the MAC with a family of PHYs
that support operation in a Low Power Mode as defined by the IEEE 802.3az
Energy Efficient Ethernet Task Force. Lower Power Mode enables both the
send and receive sides of the link to disable some functionality for power
savings when lightly loaded. Transition to Low Power Mode does not change
the link status. Frames in transit are not dropped or corrupted in transition to
and from Low Power Mode. Transition time is transparent to upper layer
protocols and applications. LLDP must be enabled in order to EEE to operate
on a link. This feature is currently available only on copper ports.
