9Step Command Remarks1. Enter system view. system-view N/A2. Enter Ethernet interface view. interface interface-typeinterface-number N/A3. Enable auto power-down. port auto-power-down By default, auto power-down isdisabled.Enabling EEE energy saving for Ethernet interfaces in up stateIMPORTANT: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 notreceived any packet for a certain period of time. The time period depends on the chip specifications andis not configurable. When a packet arrives later, the device automatically restores power supply to theinterface and the port enters the normal state.For the 10-GE copper ports of S5820V2-52Q switches, this feature is available only when the portsoperate at 10 Gbps.To enable EEE energy saving:Step Command Remarks1. Enter system view. system-view N/A2. Enter Ethernet interfaceview. interface interface-type interface-number N/A3. Enable EEE energy saving. eee enable By default, EEE energy savingis disabled.Setting the statistics polling intervalTo set the statistics polling interval in Ethernet interface view:Step Command Remarks1. Enter system view. system-view N/A2. Enter Ethernet interfaceview.interface interface-typeinterface-number N/A3. Set the statistics pollinginterval. flow-interval interval By default, the statistics polling intervalis 300 seconds.To display the interface statistics collected in the last polling interval, use the display interface command.To clear interface statistics, use the reset counters interface command.
