Information About EEE
EEE
Energy Efficient Ethernet (EEE) is an IEEE 802.3az standard that is designed to reduce power consumption
in Ethernet networks during idle periods. EEE can be enabled on devices that support low power idle (LPI)
mode. Such devices can save power by entering LPI mode during periods of low utilization. In LPI mode,
systems on both ends of the link can save power by shutting down certain services. EEE provides the protocol
needed to transition into and out of LPI mode in a way that is transparent to upper layer protocols and
applications.
EEE LPI Sleep Threshold
The EEE LPI sleep threshold specifies how long an interface should wait to go to sleep after detecting an idle
state. You can configure the threshold to be aggressive or nonaggressive.
EEE Latency
The EEE latency specifies the EEE delay that is added to your traffic. The default value is a constant latency
of 6 microseconds.
Virtualization Support
By default, Cisco NX-OS places you in the default virtual device context (VDC) unless you specifically
configure another VDC. For more information about VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual
Device Context Configuration Guide.
