Warning

Overview

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 “Important Notice” appendix.

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.

An entity refers to a domain member or an end point.

You can configure policies, referred to as recurring events or recurrences, to use time-of-day settings to automatically manage power usage.

• Management stations—Control applications and devices that use EnergyWise to monitor and

manage the power usage of domain members and end points. Management stations also send queries.

Use the management application programming interface (API) to write a power management application.

• Domain members—Cisco switches, routers, and network devices that use power. They forward

messages across an EnergyWise domain consisting of other Cisco devices and end points. They also forward and reply to queries from the management station and other domain members and aggregate power-usage information from the end points.

A domain is treated as one unit of power management and is similar to a network-management community.

• End points—Devices that use power. They only respond to queries.

Use the end-point software development kit (SDK) to implement an agent or client that participates as an EnergyWise end point.

Domain members and end points can receive power from an AC power source, a DC power source, or a power supply.

OL-19806-03

Cisco EnergyWise Configuration Guide

Creating an EnergyWise Domain

Power over Ethernet (PoE) domain members and end points can also receive power from PoE switches or Cisco EtherSwitch service modules. For example, IP phones and access points connected to a PoE switch receive power from the switch.

Creating an EnergyWise Domain

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). An EnergyWise domain consists of Cisco domain members and end points. The domain members forward messages to other members and to end points.

For example, if you have a building with a core router, 10 access switches, and 400 end points, such as phones, access points, and PCs running the end point SDK, you can create an EnergyWise domain called MyBuilding with the router and switches as domain members.

Note If you want to implement power management applications on a management station and EnergyWise

agents on the end points, the domain members must all run EnergyWise Phase 2 or later.

Chapter 1 Managing Single Entities

After you enable and configure EnergyWise on the core router and access switches, the MyBuilding 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,

Each domain member sets up a parent-child relationship with an attached end point. The child is one of the 400 end points, and the parent is the domain member. For example, an IP phone (child) is connected to a PoE switch (parent), or a PC is connected to a router.

The EnergyWise domain can also have end points running custom SDK agents.

After the domain is set, a domain member can forward queries and control messages to other domain members and endpoints.

You ca n

• Use SNMP or a management station to query every entity (domain member or end point).

• Run an EnergyWise query to receive or set power usage information.

• Use a management application, server, or CLI of a domain member to define power usage policies

or receive power usage information.

Chapter 1 Managing Single Entities

Power Levels

The devices in an EnergyWise network are from different manufacturers. To manage power usage consistently, EnergyWise uses a set of power levels.

If a domain member sends an end point a request to change the power level, the end point determines the appropriate action.

Ta b l e 1-1 Power Levels

Category Level Description

Operational 10 Full

Standby 7 Medium

Nonoperational 2 Sleep

Power Levels

9 High

8 Reduced

6 Frugal

5 Low

4 Ready

3 Standby

1 Hibernate

0 Shut off

The range is from 0 to 10.

The default is 10.

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.

For a switch, the hostname.

For an end point, see the documentation for the end point and the agent or client running on it. We recommend that you use the hostname.

For a PoE port, the default is interface.

For a switch, the default can be the model number or the supervisor model number.

For an end point, see the documentation for the end point and the agent or client running on it.

0/2.

Recurring Event

You can configure the switch to power an end point or interface on and off based on the time or date.

A recurring event, also referred to as a recurrence, uses the switch time.

The settings are only in the running configuration.

If the switch fails and then restarts, it uses the power level in the saved configuration.

Secure Domain Communication

Configure the security mode and password, referred to as the shared secret, to prevent replay attacks. You set either a strong password with Network Time Protocol (NTP) or a strong password without NTP.

When you use NTP to synchronize the time among domain members and you set a shared secret with NTP, EnergyWise uses the current time with the shared secret to enhance prevention of replay attacks.

Configuration Guidelines

By default, EnergyWise is disabled on the switch.

If you enter the no energywise level command, the switch does not immediately change the power level to the default. The power level changes when the switch restarts or when you enter the energywise level level command.

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.

If a port is in the error-disabled state:

• It appears as an EnergyWise entity in the show command output and in the collect query results. The

query results show that the port uses 0 W.

• It does not respond to a set query.

Chapter 1 Managing Single Entities

For recurring events:

• Specify time in the 24-hour format. For example, to set 0634

–

As a specific time, enter the energywise level level recurrence importance importance at 34 6 * * * interface configuration command.

–

In a time range, enter the absolute start 06:34 * * 2009 and the periodic daily 06:34 time-range configuration commands.

• The time zone is based on the end point.

–

If EnergyWise is not running on the end point (for example, a PoE end point), the specified time is based on the switch time zone.

–

If an agent or client is running on the end point, the specified time is based on the end-point time zone.

• If you configure the switch to power on an end point or a PoE port at a specific time, it powers on

within 1 minute, for example, between 0700 and 0701.

• If you configure the same recurring event for multiple end points, they all power on within 1 minute.

Note See the Release Notes for Cisco EnergyWise, EnergyWise Phase 2 on Cisco.com for software

releases with Cisco EnergyWise Phase 2.

• When you use the day_of_month and the day_of_week in the energywise level level recurrence

importance importance at minute hour day_of_month month day_of_week interface configuration

command in an EnergyWise Phase 2 software release:

1-10

–

The recurring event occurs when either the day_of_month or the day_of_week occurs first in releases earlier than the EnergyWise Phase 2 releases.

If you specify both the day_of_month and the day_of_week, the event occurs when either the day_of_month or the day_of_week is first.

If you specify the day_of_month and use a wildcard (*) for the day_of_week, the event occurs on the day_of_month.

Cisco EnergyWise Configuration Guide

OL-19806-03

Chapter 1 Managing Single Entities

–

• If you use the energywise level level recurrence importance importance at minute hour 29 2 *

interface configuration command to configure an event on February 29 in an EnergyWise Phase 2 software release:

–

When configuring domains:

• Use a strong password for the domain shared secret.

• You must configure the same security mode, either an Network Time Protocol (NTP) or a non-NTP

shared secret, for all the domain members.

You must use a strong password:

• Contains both upper and lower case characters (for example, a–z and A–Z).

Configuration Guidelines

If you use a wildcard for the day_of_month and specify the day_of_week, the event occurs on the day_of_week.

If you use wildcards for both the day_of_month and the day_of_week, the event occurs on any day.

After you upgrade the software to an EnergyWise Phase 2 release or later, a configured recurring event might occur less frequently than before the upgrade. Reconfigure the event.

Before you upgrade the software to an EnergyWise Phase 2 release or later, the event occurs every day in February.

After you upgrade the software, the event might not occur.

• Contains letters, numerals, and punctuation (for example, 0-9 and !@#$%^&*()_+|~

=\`{}[]:";'<>?,/).

• Is at least five alphanumeric characters long.

• Is not a word in any language and is not slang, dialect, or jargon.

• Is not based on personal information, such as the names of family members.

Do not use a weak password:

• Contains fewer than eight characters.

• Is a word found in a dictionary (English or foreign)

• Is any other term that is easily guessed or found in common usage, such as

The name of family, pet, friend, coworker, or fantasy character.

A computing term or name, such as a command, site, company, model, or application.

Is a birthday or another kind of personal information, such as an address or telephone number.

Is a predictable letter pattern or number pattern, such as aaabbb, qwerty, zyxwvuts, or 123321.

Any of the previous spelled backwards.

Any of the previous preceded or followed by a digit, such as secret1 or 1secret.

Using the Call In-Progress Feature

Use this feature, also referred to as activity check, to configure the switch to wait until a Cisco IP phone connected to a PoE port is not sending or receiving traffic before powering off the port.

Use the energywise activitycheck interface configuration command on these Cisco devices:

• Catalyst 6500 switches (see the Cisco IOS Release Notes for Cisco EnergyWise, EnergyWise

Phase

2 for the specific devices)

• Catalyst 4500 switches

Note Before powering off a PoE port, Catalyst 6500 and 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, and 2960 switches

• Cisco EtherSwitch service modules (NME-16ES-1G, NME-16ES-1G-P, NME-X-23ES-1G,

NME-X-23ES-1G-P, NME-XD-24ES-1S-P, NME-XD-48ES-2S-P)

• Cisco enhanced EtherSwitch service modules (SM-D-ES2-48, SM-D-ES3-48-P, SM-D-ES3G-48-P,

SM-ES2-16-P, SM-ES2-24, SM-ES2-24-P, SM-ES3-16-P, SM-ES3-24-P, SM-ES3G-16-P, SM-ES3G-24-P)

Before entering the energywise activitycheck command on devices other than Catalyst 6500 and 4500 switches, you must enable automatic quality of service (auto-QoS) for VoIP on the port with this configuration:

Chapter 1 Managing Single Entities

• All packets from the IP phone have the class of service (CoS) value 5.

To verify this, use the show mls qos maps cos-output-q privileged EXEC command to display the CoS output queue threshold map.

This example shows that CoS value 5 is mapped to queue 1 and threshold 3 on the Gigabit Ethernet

Cos-outputq-threshold map:

cos: 0 1 2 3 4 5 6 7

------------------------------------

queue-threshold: 4-3 4-2 3-3 2-3 3-3 1-3 2-3 2-3

0/1:

This is the configuration for the PoE port:

<output truncated> interface GigabitEthernet0/1 srr-queue bandwidth share 10 10 60 20 queue-set 2 priority-queue out mls qos trust device cisco-phone mls qos trust cos auto qos voip cisco-phone service-policy input AutoQoS-Police-CiscoPhone <output truncated>

• Auto-QoS for VoIP is enabled on the PoE port.

• Auto-QoS is enabled on the IP phone. The switch does not change the CoS value in the packet from

the IP phone.

1-12

Cisco EnergyWise Configuration Guide

OL-19806-03

Chapter 1 Managing Single Entities

• If the switch is connected to the IP phone through multiple Cisco devices, verify that they trust the

CoS value in incoming packets and do not change it.

• After entering the energywise activitycheck interface configuration command, verify that the

switch powers off the port when a Cisco IP phone connected to it is not sending or receiving traffic. While making a phone call

–

Run a query to set the port power level to 0. The switch should not power off the IP phone.

–

Use the show mls qos interface statistics privileged EXEC command to display the port QoS statistics, including the number of packets in queue 1.

For example, in this network, to receive an IP address from the DHCP server, the PC sends a broadcast message to the switches, which forward the message to the Internet. The DHCP server receives the message and assigns an IP address to the PC.

When the PC sends an EnergyWise message to the Layer 2 switch, it forwards the message to the Layer 3 switch instead of responding to it. The Layer 2 switch and the connected PC are in different VLANs. The Layer 3 switch also forwards the message.

If the message is forwarded to the router, the router adds the PC to the router MAC address table as a directly connected device. To prevent this, you can configure a switched virtual interface (SVI) on the Layer 2 switch so that the PC and switch are now in the same VLAN.

The PC now has access to the connected IP network and to the Internet.

• When the PC sends messages to the switch, the switch now responds to the messages instead of

forwarding them.

• The PC can also send messages to and receive messages from the IP network.

To prevent the PC from accessing the IP network, create and apply an ACL to the ingress interface on the Layer 2 switch. This ACL permits only traffic sent to an IP address of 255.255.255.255 or 20.0.0.1 and to a UDP port of 43440.

Switch(config)# access-list 102 permit udp any any eq 43440 Switch(config)# access-list 102 permit udp any 20.0.0.1 0.0.0.0 eq 43440 Switch(config)# end Switch# show access-lists Extended IP access list 102 10 permit udp any any eq 43440 20 permit udp any 20.0.0.1 0.0.0.0 eq 43440

Note When you are creating an ACL, remember that, by default, the end of the access list contains an implicit

deny statement for all packets if it did not find a match before reaching the end.

CLI Compatibility Issues

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

Note Catalyst 6500 switches do not support EnergyWise Phase 1.

To display the EnergyWise version running on your switch, use the show energywise version privileged EXEC command.

To display the software version running on your switch, use the show version privileged EXEC command.

Note To verify the EnergyWise release, use the show energywise version privileged EXEC

command. The EnergyWise release is referred to as the EnergyWise specification in the command output.

–

All domain members must have the same domain name and security mode.

–

If your switch is stacking-capable (for example, a Catalyst 3750-X, 3750-E, or 2960-S switch) and is a member of a switch stack, all the stack members must run the same EnergyWise version.

These commands in EnergyWise Phase 1 were modified:

• energywise domain domain-name secret [0 | 7] password global configuration command

We recommend that you reconfigure the EnergyWise domain with the energywise domain domain-name security {ntp-shared-secret | shared-secret} [0 | 7] shared-secret global configuration command.

If you do not reconfigure the domain, the switch synchronizes the management password with the the domain password.

• energywise management tcp-port-number global configuration command

We recommend that you reconfigure the management password for the domain with the energywise management security shared-secret [0 | 7] shared-secret port tcp-port-number global

configuration command.

Running Queries

Chapter 2 Managing Multiple Entities

EnergyWise supports these query types:

• Collect—Receive power-usage information in W from the domain members and end points.

• Save—Save the running configuration of a domain member. Use the energywise allow query save

global configuration command.

• Set—Change the power level of a domain member or end point in the running configuration.

• Sum—Summarize the information from domain members and end points.

You can filter the results with these attributes:

• 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.

• Role—Device function based on the business or deployment context.

• Name—Device identity.

• Keywords—Device descriptions (other than the name or role).

The query results show entities with importance values less than or equal to the specified value in a query.

Using Queries to Manage Power in the Domain

Beginning in privileged EXEC mode:

Command Purpose

Step 1

energywise query importance importance {keywords word,word,... | name name} collect {delta | usage} [timeout timeout]

energywise query importance importance {keywords word,word,... | name name} sum {delta | usage} [timeout timeout]

(Optional) Runs a query to display power information for the domain entities.

• importance importance—Only entities with importance

values less than or equal to the specified value respond to the query. The importance range is from 1 to 100.

• (Optional) keywords word,word—Filters the results based

on one or more keywords.

• (Optional) name name—Filters the results based on the

name. For the wildcard, use * or name* with the asterisk at the end of the name phrase.

• collect {delta | usage}—Displays power-usage information

in watts (W) from the domain members and end points.

–

delta—Displays the delta vector with the difference between the actual power usage and the maximum power usage for each power level for what-if calculations.

Chapter 2 Managing Multiple Entities

–

usage—Displays the actual power usage.

• sum {delta | usage}—Displays the summary of the

power-usage information from domain members and end points.

–

delta—Displays the delta vector.

–

usage—Displays the actual power usage.

Note In the results with the sum keyword, the Responded total

is not accurate. The Queried total is accurate and is the number of entities that respond to the query.

• (Optional) timeout timeout—Sets the time in seconds that

the management station waits for query results.

The default is 6 seconds. The range is from 1 to 180.

Repeat this step to run another query.

Command Purpose

Step 2

energywise query importance importance {keywords word,word,... | name name} set level level [timeout timeout]

Examples

(Optional) Runs a query to power on or off the domain members, PoE ports, or end points.

Caution Use this query with care. It affects both the entity on

which you enter the command and other domain entities that match the query criteria.

• importance importance—Filters the results based on the

importance value. Only entities with values less than or equal to the specified value appear. The importance range is from 1 to 100.

• (Optional) keywords word,word,...—Filters the results based

on one or more keywords.

• (Optional) name name—Filters the results based on the

name. For the wildcard, use * or name* with the asterisk at the end of the name phrase.

• set level level—Sets the power level of the entities or PoE

ports. The range is from 0 to 10.

Examples

• (Optional) timeout timeout—Sets the time in seconds that

the management station waits for query results.

The default is 6 seconds. The range is from 1 to 180.

Repeat this step to run another query.

Examples

Querying with the Name Attribute

To show the power usage of the domain entities with names beginning with shipping and with importance values less than or equal to 80, run this query on Switch

Switch# energywise query importance 80 name shipping.* collect usage EnergyWise query, timeout is 3 seconds:

Host Name Usage Level Imp

---- ---- ----- ----- ---

192.168.20.1 shipping.1 6.3 (W) 10 1

192.168.20.2 shipping.2 8.5 (W) 10 1

Queried: 2 Responded: 2 Time: 0.4 seconds

The first row (shipping.1) is from Switch 1. The second row (shipping.2) is from Switch 2, a neighbor of Switch 1.

Querying with Keywords

Chapter 2 Managing Multiple Entities

To show the power usage of IP phones with different names, different roles, and importance values less than or equal to 80, but all that have the Admin keyword, run this query on Switch 1:

Switch# energywise query importance 80 keyword Admin collect usage EnergyWise query, timeout is 3 seconds:

Host Name Usage Level Imp

---- ---- ----- ----- ---

192.168.40.2 shipping.1 6.3 (W) 10 1

192.168.50.2 orders.1 10.3 (W) 10 1

192.168.60.3 pc.1 200.0 (W) 8 75

Queried: 3 Responded: 3 Time: 0.5 seconds

Switch 1 reports two phones connected to Switch 2, a neighbor of Switch 1.

Querying to Set Power Levels

Run these queries on Switch 1 to

• Set the power level of the shipping.2 entity to 0:

Switch# energywise query importance 80 name shipping.2 set level 0

• Manually set the power level of the shipping.1 entity and the shipping.2 entity to 0:

Switch# energywise query importance 90 name shipping.* set level 0

2-6

• Set the power level of devices that have the keyword Admin to 10:

Switch# energywise query importance 60 keyword Admin set level 10 EnergyWise query, timeout is 3 seconds: !!!! Success rate is (2/2) setting entities

Queried: 2 Responded: 2 Time: 0.15 seconds

Cisco EnergyWise Configuration Guide

OL-19806-03

Chapter 2 Managing Multiple Entities

Verify the power levels:

Switch# energywise query importance 85 keyword Admin collect usage EnergyWise query, timeout is 3 seconds:

Host Name Usage Level Imp

---- ---- ----- ----- ---

192.168.40.2 shipping.1 6.3 (W) 10 1

192.168.50.2 orders.1 10.3 (W) 10 1

192.168.60.3 pc.1 200.0 (W) 8 85

Queried: 3 Responded: 3 Time: 0.9 seconds

You can also use the show energywise usage privileged EXEC command on Switch 1 and Switch 2 to verify the power levels.

Setting the Time-Out Value

When you use the default timeout value with the energywise query importance importance {keywords word,word, ... | name name} set level level timeout timeout command and you wait more than 6 seconds

to receive query results, you should increase the timeout value.

For example, if you set a timeout value of 60 seconds and you wait less than 60 seconds to receive query results, the actual query time appears.

Switch# energywise query importance 90 name * set level 0 EnergyWise query, timeout is 60 seconds: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!! Success rate is (48/48) setting entities

Examples

Switch# energywise query importance 90 name * collect usage EnergyWise query, timeout is 60 seconds:

section in the “Managing Single Entities” chapter.

For a recurring event, to configure multiple dates and times using the cron format (minute hour day_of_month month day_of_week)

• Use a comma (,) to specify a list of values without spaces between the values, for example, 1,3,4,7,8.

• Use a dash (-) to specify a range of values, for example, 1-6 (same as 1,2,3,4,5,6).

• Use an asterisk (*) for a wildcard.

• Use a slash (/) to skip a specific number of values. For example

–

Enter */15 * * * * for the event occurs every 15 minutes.

–

Enter 0-59/3 * * * * or 0,20,40 for the event to occur every 20 minutes.

–

Enter */61 * * * * for the event to occur every hour.

–

Enter * */3 * * * or 0,3,6,9,12,15,18,21 for the event to occur every three hours.

For Catalyst 4500 switches running EnergyWise Phase 2 and later:

• For high availability

–

To perform an ISSU downgrade from a Cisco IOS release supporting EnergyWise Phase 2 to an earlier software release that does not support EnergyWise, disable EnergyWise on the switch first.

–

To perform an ISSU downgrade from a software release supporting EnergyWise Phase 2 to a release supporting EnergyWise Phase 1, disable EnergyWise on the switch first because of CLI compatibility issues between EnergyWise Phase 1 and EnergyWise Phase 2.

–

To perform an ISSU downgrade from a Cisco IOS release supporting EnergyWise Phase 2 to an earlier release that does not support EnergyWise, you must remove the snmp-server enable traps energywise global configuration command from the switch configuration.

–

During an ISSU upgrade from a software release supporting EnergyWise Phase 1 to a release supporting EnergyWise Phase 2, the EnergyWise settings in the running configuration are updated. The switch sets the management password to the same domain password as in the energywise domain command. You must enter the copy running-config startup-config privileged EXEC command to save the EnergyWise settings in the configuration file.

OL-19806-03

• For stateful switchover (SSO) mode

–

On a redundant chassis operating in SSO mode, the energywise neighbor hostname udp-port-number global configuration command does not work. Use the energywise neighbor ip-address udp-port-number global configuration command to specify the IP address of the

host.

Note If your switch is running EnergyWise Phase 2, enter the no energywise domain global configuration

command to disable EnergyWise before downgrading your software to a release supporting EnergyWise Phase 1.

For more information, see the “CLI Compatibility Issues” section in the “Managing Single Entities” chapter.

• Statement 361—VoIP and Emergency Calling Services do not Function if Power Fails, page C-1

• Statement 1071—Warning Definition, page C-3

Cisco EnergyWise enables you to reduce energy consumption in your network by turning off the power to devices when they are not in use. If IP phones are part of your network, they can also be turned off through EnergyWise, in which case calls cannot be made or received, and the phones cannot be turned on except by the network administrator or according to rules established in EnergyWise by the network administrator. Laws in the location of your network might require phones to remain available for emergencies. It is your responsibility to identify the laws which apply and to comply with them. Even in the absence of a law, we strongly recommend that you designate certain phones which will always be on and available to make and receive emergency calls. These phones should be clearly identified, and all employees or others who might require emergency access to make or receive calls should be informed of the availability of these phones.
