Cisco IOS Release Notes for Cisco EnergyWise, EnergyWise Phase 2.5

---

October 21, 2011

If your switch is stacking-capable (for example, a Catalyst 3750-X, 3750-E, or 3750), the term switch refers to both a standalone switch and a switch stack unless otherwise noted.

These release notes include important information about Cisco EnergyWise Phase 2.5 and any limitations, restrictions, and documentation updates that apply to Cisco devices running EnergyWise. To verify that these release notes are correct for your switch, see the "Supported Devices" section.

For information about a specific Cisco device running Cisco EnergyWise Phase 2.5, see the release notes for the Cisco IOS software running on your device. To verify that these release notes are correct for your switch, use the show version privileged EXEC command.

For the list of EnergyWise Phase 2.5 documentation, see the "Related Documentation" section.

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 the "Importance Notice" appendix in the Cisco EnergyWise IOS Configuration Guide, EnergyWise Phase 2.5 on Cisco.com.

Compatibility Matrixes

Verify that the EnergyWise specification of the domain member is compatible with the other domain members, the management station, and the connected endpoints.

Use the show energywise version privileged EXEC command to display the Cisco IOS release, the Cisco EnergyWise specification, and the toolkit version:

DomainMember# show energywise version

EnergyWise is Enabled

IOS Version: 12.2(58)SE

EnergyWise Specification: (rel2_7)1.2

In this example

•Cisco IOS release is Cisco IOS Release 12.2(58)SE.

•Cisco EnergyWise specification is rel2_7.

•Toolkit version is 1.2.

New Features

•An EnergyWise query to analyze and display domain information.

•Wake on LAN (WoL) to remotely power on and off a WoL-capable PC.

•The clear energywise endpoints [all | cached] privileged EXEC command to remove either operational or nonoperational (cached) EnergyWise endpoints.

•EnergyWise plug and play to enable endpoint discovery without domain configuration.

•EnergyWise return-to-caller to let domain members forward responses directly to the management station without the responses passing through another domain member.

•When you use the EnergyWise endpoint software development kit (SDK) version 1.2 or the management application programming interface (API) version 1.2, we recommend that Catalyst 3750-X, 3750-E, 3750v2, 3750, 3560-X, 3560-E, 3560, 2960-S, and 2960 switches run Cisco IOS Release 12.2(58)SE.

•Cisco Unified IP Phone 6900, 7900, 8900, and 9900 series support the Cisco EnergyWise Power Save Plus mode. You can use this feature to configure the phone to sleep (power down) and wake (power up). To use this feature, your system should include an EnergyWise controller, such as a Cisco switch with the EnergyWise feature enabled. The following switches support this feature:

–Catalyst 6500 series switches running Cisco IOS Release 12.2(33)SXJ.

–Catalyst 4500 series switches running Cisco IOS Releases 3.2.0 SG and 15.0(2)SG.

–Catalyst 2960, 2960-S, 3560, 3560-E, 3560-X, 3750, 3750-E, and 3750-X series switches running Cisco IOS Release 12.2(58)SE1.

Limitations and Restrictions

You should review this section before you begin working with EnergyWise. These are known limitations that will not be fixed, and there is not always a workaround.

•EnergyWise Phase 2.5 is not backward-compatible EnergyWise Phase 1.

•EnergyWise Phase 2 is not backward-compatible with EnergyWise Phase 1.

•EnergyWise Phase 2 does not support IPv6.

•The Cisco EnergyWise software development kit (SDK) or the management application programming interface (MAPI) Version 1.2, also referred to as the EnergyWise toolkit Version 1.2, is compatible with Cisco EnergyWise Specification rel2_7. We recommend that you use the SDK or MAPI Specification rel2_7 with domain members running Cisco IOS Release 12.2(58)SE. The toolkit Version 1.2 is not backward-compatible with Cisco EnergyWise Specification rel2_5 or Cisco EnergyWise Specification rel2_6 (CSCtn68547).

Open Caveats

•CSCti19539

If you use the energywise interface configuration command, not all EnergyWise interface configurations revert to the default values.

Use one of these workarounds:

– Set each one of the interface configuration parameters to the default value.

– Use the no energywise domain global configuration command to remove the EnergyWise configuration. When you configure a new EnergyWise domain, default values are assigned to all parameters.

Obtaining Documentation and Support on the Cisco Developer Network

Cisco EnergyWise development partners can access the EnergyWise documents, API and SDK software code, and Cisco IOS software by joining the Cisco Developer Network:
http://developer.cisco.com/web/esdk/home.

You need a support contract and license to access EnergyWise resources on the Cisco Developer Network and on TAC. The business development manager who registered your licence must set up your Cisco.com account with the appropriate access privileges.

The forum, wiki, and other resources on the Cisco Developer Network provide a self-help knowledge base and community for EnergyWise application developers and programmers. You can get additional support by opening a case in the TAC Service Request Tool:
http://tools.cisco.com/ServiceRequestTool/create/launch.do.
