Energy Efficient Ethernet (EEE)
Energy Efficient Ethernet (EEE) combines MAC with ports that support operation in a
Low-Power Mode. This feature is defined by the IEEE 802.3az Energy Efficient Ethernet
Task Force. Lower Power Mode enables both send and receive sides of a link to disable
some port functionality to save power when the port is lightly loaded. Transition to Low-Power
Mode does not change the link status. Frames in transit are not dropped or corrupted during
transition to and from Low-Power Mode. This transition time is transparent to upper layer
protocols and applications.

EEE operation is subject to the following conditions:
•
Autonegotiation must be enabled to use any of the EEE modes. EEE mode is disabled
automatically when autonegotiation is disabled.
•
Enabling or Disabling EEE mode causes the port link to flap once as EEE capability
needs to be advertised. This restarts autonegotiation.
needs to be advertised. This restarts autonegotiation.
•
EEE must be disabled while running hardware or software cable diagnostics.
•
Combo (Combination) ports: Combo ports support both copper and fiber media. EEE
mode only applies to copper media. If Energy Detect mode is configured on a
combination port, it will only function when a copper media is active. EEE LPI statistics
are only collected if a copper media is used on the port. If the media on a port changes
from copper to fiber while EEE is enabled, LPI statistics collection stops until the media
changes back to copper. The outputs of the show green-mode <slot/port> and
show green-mode eee-lpi-history interface
mode only applies to copper media. If Energy Detect mode is configured on a
combination port, it will only function when a copper media is active. EEE LPI statistics
are only collected if a copper media is used on the port. If the media on a port changes
from copper to fiber while EEE is enabled, LPI statistics collection stops until the media
changes back to copper. The outputs of the show green-mode <slot/port> and
show green-mode eee-lpi-history interface
<slot/port> commands
display updated LPI statistics only if the medium is copper.
