Green Ethernet Interface Configuration

For platforms that include Green Energy features, the Green Ethernet Interface Configuration page is used to configure per-port Green Ethernet settings. Only interfaces that are capable of supporting Green Ethernet modes appear in the table. To configure the settings for one or more interfaces, select each interface to configure and click Edit. The same settings are applied to all selected interfaces.

To access this page, click System > Advanced Configuration > Green Ethernet > Interface in the navigation menu.

Green Ethernet Interface Configuration Fields

Field Description
Interface The interface associated with the rest of the data in the row. When configuring the settings for one or more interfaces, this field identifies the interfaces being configured.
Energy Detection The administrative status of Energy Detect mode on the interface. When the Energy Detect mode is enabled and a port link is down, the PHY (Physical Interface Transceiver) automatically goes down for short period of time and then wakes up to check link pulses. This mode reduces power consumption on the port when no link partner is present.
Energy Detection Status The current operational state of Energy Detect mode – either Active or Inactive.
EEE Low Power Idle The administrative mode of LPI (Low-Power Idle) on the interface. LPI can reduce power consumption on the interface during periods where no traffic is present on the interface. Enabling this mode does not affect link status and should not cause traffic loss. Note that LPI mode is available only if the interface Physical Mode is Auto Negotiate.
EEE Idle Time The amount of time allowed for the interface to move to an LPI state.
EEE Wake Time The system wake time that the interface transmits when it is enabled for EEE (Energy Efficient Ethernet). The wake time is the amount of time allowed to wake up from the low-power state that occurs when no data is transmitted.

If you change any of the parameters, click Submit to apply the changes to the system. If you want the switch to retain the new values across a power cycle, you must save the configuration.
