Enabling EEE energy saving for Ethernet interfaces in up state
IMPORTANT:
Fiber ports do not support this feature.
With Energy Efficient Ethernet (EEE) energy saving, a link-up port enters the low power state if it has not
received any packet for a certain period of time. The time period depends on the chip specifications and
is not configurable. When a packet arrives later, the device automatically restores power supply to the
interface and the port enters the normal state.
For the 10-GE copper ports of S5820V2-52Q switches, this feature is available only when the ports
operate at 10 Gbps.
