Chapter 2 Configuring EnergyWise Queries You can use these attributes to filter the results: • Importance—Rate your devices based on the business or deployment context. The range is from 1 (least important) to 100 (most important). The default is 1. For example, a desk phone has a lower importance than a business-critical emergency phone. • Keywords—Device descriptions (other than the name or role). • Name—Device identity. • Role—Device function based on the business or deployment context. • Usage—Specifies the energy usage type of the EnergyWise device. The default is consumer. – All—Devices of all usage types. – Consumer—A device that consumes power, such as a switch. – Meter—A device that measures the pass-through power, such as a power distribution unit (PDU) that sends power from a source to a connected device. – Producer—A device that generates power, such as a solar panel. The query results show domain members and endpoints with importance values less than or equal to the specified value in the query. Using Queries to Manage Power in the Domain Note If the timeout value in the energywise query importance privileged EXEC command is too short, the management station does not receive query results even if the domain members and endpoints respond to the query. For example, if you want to power off a specific phone but the timeout value in the energywise query importance command is too short, the phone is not powered off. When configuring the timeout, configure a minimum of 6 seconds to display correct output. Beginning in privileged EXEC mode: Step 1 Command energywise query analyze domain domain-name Purpose Runs a query to analyze and display information about the domain, including the domain size and the number of members and endpoints.

Queries<br />
• Using Queries to Manage Power in the Domain, page 2-19<br />
• Query Examples, page 2-22<br />
The management station sending a query receives all the power-usage responses from the <strong>EnergyWise</strong><br />
domain. The domain members use neighbor relationships to forward the query.<br />
For secure communication, the domain members use a shared secret and send only authenticated queries<br />
to the endpoints.<br />
