Green Ethernet Commands Dell Networking N1108EP-ON/N1500/N2200-ON/N3200-ON Series Switches Dell 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 Ethernet 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. It is not available on the N2200 Series switches. 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. It is not available on the N2200 Series switches. Layer 2 Switching Commands 516
