See EnergyWise partner information on the Cisco Developer Network: http://developer.cisco.com/web/esdk/home. Warning Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the emergency calling service. In the USA, this emergency number is 911. You need to be aware of the emergency number in your country. For information about this warning, see Appendix A, “Important Notice.” EnergyWise Network In a Cisco EnergyWise network, EnergyWise monitors and manages the power usage of powered devices: Cisco devices in a domain and all the connected end points. An end point can be a device connected to the network, such as an IP phone, access point, or PC. You can configure policies, referred to as recurring events or recurrences, to use time-of-day settings to automatically manage power usage. Cisco EnergyWise IOS Deployment Guide OL-19803-01 1-1

CH A P T E R 2 Configuring EnergyWise EnergyWise Domains, page 2-1 Power Levels, page 2-3 EnergyWise Attributes, page 2-5 Using the Call In-Progress Feature, page 2-10 EnergyWise Domains An EnergyWise domain is treated as one unit of power management and is similar to a network-management community (for example, a VLAN Trunking Protocol [VTP] domain). A domain consists of switches, other network devices, and end points. The domain members forward messages to other members and to end points. Domain members and end points can receive power from an AC power source, a DC power source, or a power supply. A domain member or end point belongs to only one domain. When you enable EnergyWise on the domain members, the domain configures itself. Neighbor relationships are set among the domain members. Domain members use CDP when it is enabled or EnergyWise UDP messages to automatically discover neighbors. You can manually configure static neighbors, A domain should be the same as a metered or submetered area in your organization. A domain can be the same as a Layer 2 subnet. We recommend that a domain has no more than 50 domain members. For information about domains, see the Cisco EnergyWise Partner Development Guide on the Cisco Developer Network or the Cisco EnergyWise Configuration Guide on Cisco.com. Examples In the sample network in the “Overview” chapter, the routers and switches are domain members, and the connected power over Ethernet (PoE) devices, IP phones and access points, are end points. For information about domain members and end points, see the “Overview” chapter. Cisco EnergyWise IOS Deployment Guide OL-19803-01 2-1
Chapter 2 Configuring EnergyWise EnergyWise Domains Guidelines An EnergyWise domain usually has a set of devices that belong to one unit of power management. This could be a metered or submetered area of an organization. By default, EnergyWise is disabled. All domain members must run either Energy Phase 1 or EnergyWise Phase 2 or later. To verify the EnergyWise release from the command-line interface (CLI), use the show energywise version privileged EXEC command. Note The EnergyWise release is referred to as the EnergyWise specification in the show command output. On Switch A SwitchA# show energywise version EnergyWise is Enabled IOS Version: 12.2(53)SE2 EnergyWise Specification:1.0.n When you enable EnergyWise on a domain member, EnergyWise assigns the device to a domain, sets the domain security mode, and sets the domain password to authenticate communication in the domain. All domain members have the same EnergyWise major release (1.n.n). Enter the energywise domain domain-name security {ntp-shared-secret shared-secret} [0 7] domain-password [protocol udp port udp-port-number [interface interface-id ip ip-address]] global configuration command on the domain members. Use the same domain name, security mode, and password. – When naming the domain name, use a character string that describes the domain members. – We recommend that a domain have up to 50 Cisco network devices in a metered or submetered area in a facilities deployment, for example, a building or one floor of the building. Table 2-1 Domain Configuration in the Sample Network Domain name Bldg1 Security mode shared secret (use a strong password without NTP) Domain password Test4%doMain Management station communication with the domain UDP IP address Depends on the domain member port 43440 On Switch A SwitchA(config)# energywise domain bldg1 security shared-secret 0 Test4%doMain protocol udp port 43440 IP 192.168.1.10 Enter the energywise domain global configuration command on the other domain members to enable EnergyWise. Cisco EnergyWise IOS Deployment Guide 2-2 OL-19803-01
Chapter 2 Configuring EnergyWise Power Levels To verify the EnergyWise configuration, use the show energywise domain privileged EXEC command. On Switch A SwitchA# show energywise domain Name : SwitchA Domain : bldg1 Protocol : udp IP : 192.168.1.10 Port : 43440 To see discovered or static neighbors, use the show energywise neighbors privileged EXEC command. Switch A discovers Switch B.

Configure Switch C as a static neighbor of Switch A. SwitchA(config)# energywise neighbor 192.168.2.10 The default is 1. SwitchA# show energywise neighbors Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone Id Neighbor Name Ip:Port Prot Capability -------------------------------4 SwitchB 192.168.1.20:43440 udp S I 5 SwitchC 192.168.2.10:43440 static S I For configuration guidelines, see the Cisco EnergyWise Configuration Guide on Cisco.com. Power Levels To manage power on Cisco and non-Cisco devices, EnergyWise uses a set of power levels. The range is from 0 to 10. The default is 10. Cisco EnergyWise IOS Deployment Guide OL-19803-01 2-3
Chapter 2 Configuring EnergyWise Power Levels Examples Mapping the EnergyWise power levels to the Advanced Configuration and Power Interface (ACPI) states: Table 2-2 EnergyWise to ACPI Mapping Mode EnergyWise Level PC Power State EnergyWise Label Operational 10 G0 Full 9 G0 High 8 G0 Reduced 7 G0 Medium 6 G0 Frugal 5 G0 Low 4 G1, S1 Ready 3 G1, S2 Standby 2 G1, S3 Sleep 1 G1, S4 Hibernate 0 G2, G3 Shut Standby Nonoperational Guidelines The power usage in watts (W) for an EnergyWise power level depends on your EnergyWise-enabled device. See the device documentation for information. A Cisco switch does not support level 0. You cannot turn off the power on a switch. A PoE end point, such as IP phone, receives power from a PoE switch port. The power level is for the port. The port supports levels 0 to 10. If the port power level is 0, the port is powered off. If the power level is from 1 to 10, the port is on. If the power level is 0, enter a value to power on the PoE port to which the end point is connected. For a switch with PoE ports, such as a PoE-capable switch: When you add the switch to a domain, EnergyWise is enabled on the switch and all the PoE switch ports. Use the energywise level 0 interface configuration command to power off a PoE port. You cannot use the energywise level 0 global configuration command to power off the switch. Cisco EnergyWise IOS Deployment Guide 2-4 OL-19803-01
Chapter 2 Configuring EnergyWise EnergyWise Attributes EnergyWise Attributes EnergyWise attributes are user-specified values on domain members and end points that provide context about how the device is used in your organization. You can set keywords for devices and rate them based on the importance in the organization. Use attributes to search for and control devices. Importance, page 2-6 Keywords, page 2-7 Role, page 2-8 Configuration Example, page 2-9 Cisco EnergyWise IOS Deployment Guide OL-19803-01 2-5
Chapter 2 Configuring EnergyWise EnergyWise Attributes Importance Use this attribute to 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. Example A typical office environment has several types of phones. When using EnergyWise, you can rate the phones based on the business context. A public desk phone has a lower importance (for example, 10) than a business-critical emergency phone (for example, 100). Guidelines Set the importance based on Device user and device importance For example, a PC and a phone for a customer-service engineer is more important than a PC and a phone for lobby use. Device function Assign a higher importance according to the business context. For example, a business-critical emergency phone is more important than a guest phone. For example, a PoE switch provides power to an end-point IP phone and to other connected devices. The switch is more important than the connected devices. Table 2-3 Example of Importance Based on the Context Type Range Emergency response devices 90–100 Executive or business-critical employees 80–89 Regular employees 70–79 Staff or support personnel (PCs and IP phones) 60–69 Public or guest devices 40–59 Decorative or hospitality devices such as microwave ovens 0–39 Cisco EnergyWise IOS Deployment Guide 2-6 OL-19803-01
Chapter 2 Configuring EnergyWise EnergyWise Attributes Keywords Use keywords to tag devices or interfaces, which you can specify in queries. You can then group devices in a domain based on context to manage and control them. This optional attribute is a device description (other than the name or role) for which query results are filtered. By default, no keywords are defined. Examples IT, lobby, HumanResources, Accounting, StoreRoom, CustomerSpace, router, phone, floor2, or SoftwareLab. Guidelines You can assign multiple keywords to a device. Separate the keywords with commas. Do not use spaces between keywords. You can enter alphanumeric characters and symbols such as #, (, , !, and &. Do not enter an asterisk (*) or a blank space between the characters and symbols. Cisco EnergyWise IOS Deployment Guide OL-19803-01 2-7
Chapter 2 Configuring EnergyWise EnergyWise Attributes Role This attribute is the device function based on the business or deployment context. The role is a single value to group devices based on a specific use. Defaults: For a PoE port, the default is interface. For a domain member, the default is the model number. For an end point, see the end-point documentation. Examples For interfaces, TellerAccess or PublicAccess. For phones, SalesPhone or PrivatePhone. Guidelines Device type For example, phone, PC, switch, or router. Business role based on the connected user to the end point. For example – Lobby, Teller, HelpDesk, or GuardDesk. – KioskPC, CashierPC, or OperatorPC. Cisco EnergyWise IOS Deployment Guide 2-8 OL-19803-01
Chapter 2 Configuring EnergyWise EnergyWise Attributes Configuration Example In the sample EnergyWise network in the “Overview” chapter, use the energywise {importance importance keywords word,word,. name name role role} interface configuration command to set these attributes. Table 2-4 IP Phone and Access Point Attributes Attribute IP Phone Access Point Importance 60 75 Level 10 10 Keywords HR, Bldg1, Private HR, Bldg1, Zone3 On Switch A SwitchA(config-if)# energywise importance 60 SwitchA(config-if)# energywise level 10 SwitchA(config-if)# energywise keywords HR,Bldg1,Private Enter the energywise {importance importance keywords word,word,. name name role role} interface configuration command on the other domain members, IP phones, and access points. To verify the EnergyWise configuration, use the show energywise children provisioned privileged EXEC command.

Chapter 2 Configuring EnergyWise Using the Call In-Progress Feature Using the Call In-Progress Feature Use this feature, also referred to as activity check, to configure the switch port to wait until a Cisco IP phone connected to a PoE port is not sending or receiving traffic before the switch powers off the port. Note Catalyst 6500 switches use interface statistics to determine when a Cisco IP phone connected to the PoE port is not sending or receiving traffic. Use the energywise activitycheck interface configuration command on these Cisco devices: Note Catalyst 4500 switches Before powering off a PoE port, Catalyst 4500 switches use interface statistics to determine when a Cisco IP phone connected to the PoE port is not sending or receiving traffic. Catalyst 3750-X, 3750-E, 3750, 3560-X, 3650-E, 3560, 2975, and 2960 switches Before enabling this feature on devices other than Catalyst 4500 switches, you must Verify that automatic quality of service (auto-QoS) is enabled on the PoE port and on the connected IP phones. If the switch is connected to IP phones through multiple Cisco devices, verify that they trust the class of service (CoS) value in incoming packets. To enable a domain member to verify that the connected PoE IP phone is not sending or receiving traffic before the member powers off the PoE port, use the energywise activitycheck interface configuration command. For information about the energywise activitycheck interface configuration command, see the “Using the Call In-Progress Feature” section in the “Managing Single Entities” chapter in the Cisco EnergyWise Configuration Guide on Cisco.com: ywise/phase2/ios/configuration/guide/ one ent.html Cisco EnergyWise IOS Deployment Guide 2-10 OL-19803-01
CH A P T E R 3 Running Queries You can use queries to Receive power-usage information in watts (W) from the domain members and end points. Change the power level of a domain member or end point in the running configuration. Summarize the information from domain members and end points. The management station (a domain member in the sample network in the “Overview” chapter) or the switch sending a query through the command-line interface (CLI) receives all the power-usage responses from the EnergyWise domain. The domain members use neighbor relationships to forward the query. For secure communication, the domain members use a shared secret, or password, and send only authenticated queries to the end points. Figure 3-1 Query Requests and Replies 3 1 4 3 3 3 4 2 3 4 276241 4 1 Sends queries and messages to the domain 3 Sends queries and messages from domain members and end points 2 Replies to queries and messages from the domain 4 Replies to queries and messages from domain members and end points Cisco EnergyWise IOS Deployment Guide OL-19803-01 3-1
Chapter 3 Running Queries Examples: Powering On and Power Off Devices Note Examples: Powering On and Power Off Devices, page 3-2 Examples: Summarizing Power Usage, page 3-4 Examples: Collecting Power Usage, page 3-4 The examples are Cisco IOS queries in the sample EnergyWise network configured in the “Overview” and “Configuring EnergyWise” chapters. Examples: Powering On and Power Off Devices Use the energywise query importance importance {keywords word,word,. name name} set level level [timeout timeout] privileged EXEC to power devices on or off. Only devices with importance levels less than or equal to the importance value respond to the query. Powering Off IP Phones Enter this command on any domain member in Building 1 to power off any interface that has the public keyword. On Switch B SwitchB# energywise query importance 60 keywords public set level 0 The management station filters the results based on the importance value. The domain members power off the connected IP phones, which have importance values less than or equal to 60. Powering Off the End Points Enter this command on any domain member in Building 1. On Router B RouterB# energywise query importance 100 name * set level 0 Powering Off Devices Based on the Importance Value Enter this command on any domain member in Building 1 to power off every interface and end point. On Switch B SwitchB# energywise query importance 60 keywords * set level 0 The domain members power off only the IP phones with an importance value of 60. The access points have an importance value of 75. Cisco EnergyWise IOS Deployment Guide 3-2 OL-19803-01
Chapter 3 Running Queries Examples: Powering On and Power Off Devices Powering Devices Based on Keywords When running queries to power devices on or off, we recommend that you use manually configured device names. Note When you use the default device name in a query and you power off the device, you might not be able to find it to power it on again if the name has change. These are the attributes for the sample EnergyWise network in the “Overview” chapter.
