ECOFRIENDLY
LPI
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.
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 the
Triggers Feature Overview and Configuration Guide
.
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:
awplus#
configure terminal
awplus(config)#
interface port1.0.2
awplus(config-if)#
ecofriendly lpi
To enable the eco-friendly LPI feature on a range of switch ports, port1.0.2-
port1.0.4, use the following commands:
awplus#
configure terminal
awplus(config)#
interface port1.0.2-port1.0.4
awplus(config-if)#
ecofriendly lpi
To disable the eco-friendly feature on port1.0.2, use the following commands:
awplus#
configure terminal
awplus(config)#
