Chapter 5 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.
For more information, see the “Additional Information” section on page 5-18.
EnergyWise Network
An EnergyWise network has EnergyWise entities in a domain.
