Chapter 4 Configuring Cisco EnergyWise

Managing Single Entities

EnergyWise uses a distributed model to manage energy usage.

Switches are grouped in an EnergyWise domain and become domain entities. They receive messages
from and send them to other domain entities.

An entity in the EnergyWise domain responds to queries.

An entity participating in EnergyWise controls the power usage of connected PoE devices, such as
an IP phone, an IP camera, or a PoE-enabled device. For example, a Catalyst switch sends a
power-off message to an IP phone.

On an EnergyWise-enabled entity

The entity always participates in EnergyWise.

PoE ports participate in EnergyWise.

Non-PoE ports do not participate in EnergyWise.

EnergyWise Domain

An EnergyWise domain can be an EnergyWise network.

The domain is treated as one unit of power management.

Entities have neighbor-to-neighbor relationships with other domain entities.
