Explanation:
Cisco EnergyWise Neighbor Discovery Process
The Cisco EnergyWise neighbor discovery process is the mechanism by which domain members
discover each other and populate their Cisco EnergyWise neighbor tables. Cisco EnergyWise
queries can subsequently be distributed to all domain members using the neighbor relationships to
monitor and control the power usage of devices within a domain. Cisco EnergyWise domain
members automatically discover their neighbors through one of two mechanisms:
UDP broadcast packets are automatically sent out switch ports which support Cisco EnergyWise,
regardless of whether the interfaces are configured with the no energywise interface-level
command. CDP packets are sent when CDP is configured for the switch ports.http://www.cisco.com/en/US/docs/solutions/Enterprise/Borderless_Networks/Energy_Management
