Components Used

The information in this document is based on Cisco Catalyst 3750 Series Switches.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Background Information

Cisco EnergyWise is a power management feature that provides the ability to monitor and control power across the IT infrastructure. Cisco EnergyWise provides a framework by which the network itself can be used to open power management to all device types.

A Cisco EnergyWise domain is an administrative grouping of devices for the purpose of power monitoring and control. Cisco EnergyWise endpoints that support the EnergyWise SDK client respond to EnergyWise queries initiated from management applications or other domain members using the Cisco EnergyWise protocol.

Configure

In this section, you are presented with the information needed to configure the Cisco EnergyWise features described in this document.

Note: Use the Command Lookup Tool (registered customers only) in order to obtain more information on the commands used in this section.

Verify

Use this section to confirm that your configuration works properly.

The Output Interpreter Tool (registered customers only) (OIT) supports certain show commands. Use the OIT to view an analysis of show command output.

Use the show energywise command in order to display the EnergyWise settings and status.

For example:

Switch#show energywise
Module/
Interface   Role              Name                  Usage      Lvl   Imp  Type
---------   ----              ----                  -----      ---   ---  ----
            access4lab1       Switch                45.0  (W)  10    80   parent

Use the show energywise children command in order to display the status of the connected end point.

For example:

Switch#show energywise children
Module/
Interface   Role              Name                  Usage      Lvl   Imp  Type
---------   ----              ----                  -----      ---   ---  ----
            access4lab1       Switch                45.0  (W)  10    80   parent
Fa1/0/3     IP Phone 7975     SEP0022905B90D4       12.0  (W)  10    1    PoE

Total Displayed: 2      Usage: 143.3

Use the show energywise children provisioned command in order to display a summary of the EnergyWise information for the switch and the connected end points.

For example:

Switch#show energywise children provisioned
Module/
Interface   Role              Name                  Usage      Lvl   Imp  Type
---------   ----              ----                  -----      ---   ---  ----
            access4lab1       Switch                45.0  (W)  10    80   parent

Use the show energywise level current command in order to display the actual power levels for the domain member. When you use the energywise level level recurrence importance importance time-range time-range-name global configuration command, the output of show energywise level current is shown in the next example.

For example:

Switch#show energywise level current
Interface   Name                     Level  Value
---------   ----                     -----  -----
