ecofriendly lpi
Use this command to conserve power by enabling the eco-friendly LPI (Low Power Idle)
feature. This feature reduces the power supplied to the ports by the switch whenever the
ports are idle and are connected to IEEE 802.3az Energy Efficient Ethernet compliant host
devices. See the section
“Save Power With the Eco-Friendly Feature” on page 1.32 .
LPI is a feature of the IEEE 802.3az Energy Efficient Ethernet (EEE) standard. LPI lowers
power consumption of switch ports during periods of low link utilization when connected
to IEEE 802.3az compliant host devices. If no data is sent then the switch port can enter a
sleep state, called Low Power Idle (LPI), to conserve power used by the switch.
Use the no variant of this command to disable the eco-friendly LPI feature.
Syntax ecofriendly lpi
no ecofriendly lpi
Default The eco-friendly LPI feature is disabled by default.
Mode Interface Configuration for a switch port, or Interface Configuration for a range of switch
ports.
Usage For an example of how to configure a trigger to enable the eco-friendly LPI feature, see
“Reduce Power Supplied to Ports” on page 76.9 .
All ports configured for LPI must support LPI in hardware and must be configured to auto
negotiate by default or by using the
speed and duplex commands as needed.
Examples To enable the eco-friendly LPI feature on a switch port, port1.0.2, use the following
commands:
To enable the eco-friendly LPI feature on a range of switch ports, port1.0.2-
port1.0.4 , use the following commands:
To disable the eco-friendly feature on port1.0.2, use the following commands:
