You do not need to select a port to configure the LPI sampling interval and maximum number
of samples to keep. These settings are global, and the values you specify are applied to all
ports. To configure the LPI settings for the switch:
Energy Detect Admin Mode Shows whether Energy Detect Mode is administratively enabled on the port.
Energy Detect Operational
S
tatus
Shows the current operational status of the Green Mode for the selected
port.
Short Reach Admin Mode Shows the administrative status of Short Reach Mode on the port. With short
reach mode enabled, PHY goes into low power mode when cable length is
less than a given limit.
Short Reach Operational
S
tatus
Indicates whether the port is in low-power mode due to the cable length.
EEE Admin Mode
Shows the administrative status of Energy Efficient Ethernet Mode on the
