• A Cisco® EnergyWise domain is a logical grouping of Cisco Devices • Cisco devices assigned to an EnergyWise domain self organize to form an EnergyWise cloud • Cisco EnergyWise members can propagate Cisco EnergyWise messages across the network • Cisco EnergyWise domain members share neighbor relationships with each other • The domain is a single unit of energy management for a customer Cisco EnergyWise Domain© 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 17

Begin by creating an EnergyWise domain. This activates EnergyWise on the switch: Switch# config t Switch(config)# energywise domain myDomain secret 0 mySecret protocol udp port 43440 ip 2.2.4.30 Switch(config)# exit Verify that EnergyWise is active, and report total available power Switch# show energywise Interface Role Name Usage Lvl Imp Type --------- ---- ---- ----- --- --- ---- PoE Switch C3750 86.0 (W) 10 1 parent Lvl = Level, power level, 0-10 Imp = Importance, a relative number used in power management Switch# show energywise domain Name : C3750-48P-149 Domain : myDomain Protocol : udp IP : 2.2.4.30 Port : 43440© 2010 Cisco and/or its affiliates.

A Query command can be used to set power levels in the Domain. In this example, the power level is set to 10 (on full) for all devices with any name that have a importance of 50 or lower. Individual devices with specific names or keywords can also be specified, including wildcards for part of the name or keyword. Switch# energywise query importance 50 name * set level 10 EnergyWise query, timeout is 3 seconds: !!!!!!!!!!!!!!!!!!!!!!! Success rate is (47/47) setting entities Queried: 47 Enacted: 47 Time: 0.16 seconds If importance 100 is specified and name *, all devices with any name will be set to power level 10.
