Feature Information for Cisco EnergyWise Branch Routers

Configuring Cisco EnergyWise Feature for Branch Routers

---

OL-22157-01

First Published: March 12, 2010

Revised: May 16, 2011

Cisco EnergyWise is a technology that measures, monitors, and manages the power usage of powered devices, Cisco devices in a domain, and the end points connected to them. The end points communicate with the power management station through Cisco devices, such as the Cisco 800 series routers, Cisco 1900 series routers, Cisco 2900 series routers, and Cisco 3900 series routers. You can also configure policies to manage the power usage. For more information about how EnergyWise works, seee Cisco EnergyWise Configuration Guide, EnergyWise Phase 2 at Cisco.com.

Cisco EnergyWise is supported on the following Cisco branch routers and their modules:

•Cisco 3900 Series

•Cisco 2900 Series

•Cisco 1900 Series

•Cisco 890

•Cisco 880

•Cisco 860

•Cisco Service Module (SM)

•Cisco Internal Service Module (ISM)

•Cisco Next Generation of packet voice/data module (PVDM3)

Restrictions for Cisco EnergyWise Branch Routers

The following are the restrictions for Cisco EnergyWise Branch Routers:

•Time-out for Cisco EnergyWise Level Change

•EnergyWise Activity Check for PoE

•Power Stacking

•Cisco EnergyWise Version

Time-out for Cisco EnergyWise Level Change

Service Ready Engine (SRE) modules require time to power down or bring up modules to a stable state. If the SRE module is running an application, it requires a 2-minute time-out interval to reflect the actual change in Cisco EnergyWise level. Any Cisco EnergyWise level change in this 2-minute time-out does not take effect and you must retry after the specified time-out interval. If the SRE module is not running an application, the time-out interval is less than two minutes.

This restriction is specific to the following service modules only:

•ISM-SRE-300-K9

•SM-SRE-700-K9

•SM-SRE-900-K9

EnergyWise Activity Check for PoE

The following HWIC/Etherswitch PoE ports do not support EnergyWise activity check:

•HWIC-4ESW with ILPM4 daughter card

•HWIC-D-9ESW with ILPM8 daughter card

•HWIC-4ESG-P

•EHWIC-9ESG-P

When energywise level is set to 0, connected Cisco IP phones are powered off irrespective of call status.

When PoE ports are configured to "power inline never", it takes precedence over energywise level settings on the port.

Power Stacking

Cisco EnergyWise power stacking is not supported on the Etherswitch modules supported on Cisco ISR and Cisco ISR G2 platforms.

Cisco EnergyWise Version

Both the branch router and switch must use the same Cisco EnergyWise specification and version. To check the version, use the show energywise version command.

About Cisco EnergyWise Branch Routers

ISR G2 supports the following EnergyWise entities:

•Parent—Motherboard is the energywise parent entity. The parent entity is responsible for collection and report of all the child power and nanny power.

•Child—All Service Module (SM), Integrated Service Module (ISM), PVDM3 module, and HWIC Ether switch PoE ports act as child entities.

•Nanny—End-points that are connected to Fast/Gigabit interface, which need energywise events to be handled by parent.

•Neighbor—Entity where another energywise instance is running on it. Neighbor communicates with other neighbors in energywise domain with CDP and UDP protocol. For example, routers and switches which run energywise fall in this category.

•Child and Neighbor (Special relationship)—Special switch modules that are plugged into the Cisco ISR G2 run separate instances of energywise. These modules act as a child and neighbor based on the status of the energywise instance.

Figure 1 shows the total power consumed by a Cisco EnergyWise domain using a Cisco ISR G2 platform. The EnergyWise domain of a network is independent of the physical domain as long as there is connectivity between the physical domains. In the example below, Building B is outside the power domain; although it is connected to the distribution.

Table 5 Feature Information for Cisco EnergyWise Branch Routers

Feature Name	Releases	Feature Information
Report platform power (parent)	15.0(1)M2	For Cisco EnergyWise, every ISR G2 platform is an entity. The MCU device on the platform measures the total power consumed by the ISR G2 platforms. Platform power includes the following: •Various hardware parts on the motherboard: –Fan –CPU –ASICs) •HWICs •Legacy NM (plugged in via SM2NM port adaptor) The following are separately reported as child power, so these are not included in platform power: •Power consumed by PVDM3 •ISM •Service Module and Enhanced EtherSwitch Module •Power consumed by POE ports on modules On the Cisco 860, 880, and 890 platforms, the platform power consumption has a constant value.
Report SM power (child-neighbor)		SMs and Enhanced EtherSwitch Modules are the only two modules whose power is reported as separate child power. Also, SM does not have EnergyWise running (unlike Enhanced EtherSwitch, which may have EnergyWise running on the module). So, for Enhanced EtherSwitch the power consumed is reported as separate SM child power. EtherSwitch is a special kind of SM, which can never be the child of a platform. Its power is reported as part of platform power.
Report ISM power (child)		The power of ISMs is reported separately.
Report PVDM power (child)		Only Next Generation High Density PVDM3 Modules are supported as PVDM child. Its power is reported separately under the child's power, and is not included in the platform power. For other PVDMs, the power consumed is included in or as a part of platform power, and is not a separate child entity. The PVDM driver also supports activity-in-progress feature. If there are calls in the system and a query to shutdown is received, the driver reports back activity-in-progress and the module is not shutdown.
Report PoE power (child)	15.0(1)M2	The router can control the PoE power consumed by phone on HWIC. Only the Cisco HWIC-D-9ESW-POE and Cisco HWIC-4ESW-POE support PoE on the ISR G2 platforms. On the ISR G2 modules, the actual PoE power consumed cannot be measured. So power that is reported by phone or based on the class of the phone is reported. Like the Cisco ISR G2 modules, there is no capability to measure actual POE power on the 860, 880, and 890 platforms.
Nanny support (child)		All ethernet interfaces including front panel, as well as all the modules that have ethernet interfaces (like NM-16ESW) support Nanny negotiation. The ISRG2 platforms support Nanny Protocol on fast ethernet on the following: •POE interfaces. •Routed/L3 ports Enhanced Etherswitch Modules and 16 Port Ethernet Switch Module NM-16ESW. •Motherboard interfaces. The ISRG2 routers do not support Nanny Protocol on the remaining ethernet L2 interfaces, as well as other non-ethernet interfaces like DSL/E1/T1. The POE/L2 interfaces on Enhanced EtherSwitch Module and EtherSwitch support Nanny Protocol and the ISR G2 platforms do not directly control the POE ports on these modules. All Ethernet interfaces on Cisco 860, 880, and 890 platforms support Nanny negotiation.
Change SM power (child)		Based on the EnergyWise level supported, only Enhanced EtherSwitch and Service Module power can be changed. For both the modules, the supported power levels are 0 (shutdown) and 1 through 10 (full power).
Change ISM power (child)		Internal Service Modules (ISM) support a power level of 0 (shutdown) and 1 through 10 (full power).
Change PVDM power (child)	15.0(1)M2	The Next Generation High Density PVDM3 Modules support the following power levels: •0, 1: PVDM in reset mode (still consumes minimal power, approximately 2W) •2 through 10: Full (Normal operation).
Change POE power (child)		The ISR G2 platforms have the ability to shutdown POE ports on the modules that have POE ports. Levels supported are 0 (for shutdown) and 1 though 10 (all for full power). On the 860, 880, and 890 routers, the POE ports can be shut down or can be running full power.
MIB		All objects and traps in the CISCO-ENERGYWISE-MIB.my MIB are supported on the ISR G2 platforms and the 860, 880, and 890 platforms.
Etherswitch Network and Enhanced Etherswitch Module		Etherswitch Network and Enhanced Etherswitch Module is a special module which can run Cisco EnergyWise. The relationship between the router and the module is a child-neighbor relationship, that is, the module is the neighbor of the router, as well as a child of the router or platform. If Cisco EnergyWise is running on the module, it should be in the same domain as the router. Having the module and the router running in different domains is not supported. An IOS error message is displayed if this configuration is detected. EtherSwitch Module is not a child of the router. So, the power consumed by EtherSwitch Module is always reported or included in the platform power.
