1. Introduction
This document defines a subset of the Management Information
Base (MIB) for use with network management protocols for power
and energy monitoring of network devices and devices attached to
the network, as specified in the Power Management Architecture
[EMAN-FMWK], which in turn, is based on the Power Monitoring
Requirements [EMAN-REQ] .
This module's special focus is on monitoring energy-aware
networks and devices. The module addresses device
identification, context information, and relationships between
reporting devices, remote devices, and monitoring probes.
Devices and their sub-components may be characterized by the
power-related attributes of a physical entity present in the
ENTITY MIB, even though ENTITY MIB compliance is not a
requirement due to the variety and broad base of devices
concerned with energy management.
1.1. Energy Management Document Overview
The EMAN standards provides network administrators with energy
management.
This document, which specifies the Energy-aware Networks and
Devices MIB document is based on the Energy Management Framework
[EMAN-FMWK], per the Energy Management requirements specified in
[EMAN-REQ], which allows networks and devices to become energy
aware.
The Power and Energy Monitoring MIB [EMAN-MON-MIB] contains the
managed objects for monitoring of power states and energy
consumption/production. The monitoring of power states
includes: retrieving power states, properties of power states,
current power state, power state transitions, and power state
statistics. This MIB provides the detailed properties of the
<Parello, Claise> Expires June 22, 2011 [Page 3]
Internet-Draft <Energy-aware Networks and Devices MIB> Dec 2010
actual energy rate (power) and of accumulated energy, along with
the power quality.
The applicability statement document [EMAN-AS] provides the list
of use cases, cross-reference between existing standards and the
EMAN standard, and shows how the EMAN framework relates to other
frameworks.
EDITOR'S NOTE: [EMAN-MON-MIB] and [EMAN-AS] are not EMAN working
group documents. Hence, these references will be changed in the
future.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the
current Internet-Standard Management Framework, please refer to
section 7 of RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store,
termed the Management Information Base or MIB. MIB objects are
generally accessed through the Simple Network Management
Protocol (SNMP). Objects in the MIB are defined using the
mechanisms defined in the Structure of Management Information
(SMI). This memo specifies MIB modules that are compliant with
SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58,
RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
3. Use Cases
Requirements for power and energy monitoring for networking
devices are specified in [EMAN-REQ]. The requirements in [EMAN-
REQ] cover devices typically found in communications networks,
such as switches, routers, and various connected endpoints. For
a power monitoring architecture to be useful, it should also
apply to facility meters, power distribution units, gateway
proxies for commercial building control, home automation
devices, and devices that interface with the utility and/or
smart grid. Accordingly, the scope of the MIB modules in this
document is broader than that specified in [EMAN-REQ].
4. Terminology
The definitions of basic terms like Energy Management, Energy
Monitoring, "Power, Energy, and Energy Consumption", Power
Monitor, Power Monitor Parent, Power Monitor Child, Power
<Parello, Claise> Expires June 22, 2011 [Page 4]
Internet-Draft <Energy-aware Networks and Devices MIB> Dec 2010
Monitor Meter Domain, Power Level, and Manufacturer Power Level,
Nameplate Power, Power Proxy, Power Aggregator, Power
Distributor can be found in the Power Management Architecture
[EMAN-FMWK].
EDITOR'S NOTE: not sure if all terms will be used in the final
version of the draft
EDITOR'S NOTE: [EMAN-FMWK] is an informational non normative
reference. Is this fine?
5. Architecture Concepts Applied to the MIB Module
This section describes the basic concepts specified in the Power
Monitor Architecture [EMAN-FMWK], with specific information
related to the MIB module specified in this document
This subsection maps to the section "Architecture High Level
Concepts" in the Power Monitoring Architecture [EMAN-FMWK].
5.1 Power Monitor Information
Refer to the "Power Monitor Information" section in [EMAN-FMWK]
for background information. An energy aware device is
considered an instance of a power monitor as defined in the
[EMAN-FMWK].
The Power Monitor information is specified in the MIB module
primary table, i.e. the pmTable. Every Power Monitor SHOULD
have a printable name pmName, and MUST HAVE a unique Power
Monitor index pmIndex.
The pmIndex is a unique index greater than zero for each Power
Monitor. It is recommended that values be assigned sequentially
starting from 1. The value for each pmIndex must remain
constant at least from one re-initialization of the entity's
network management system to the next re-initialization. In
addition, the Power Monitor can potentially have an
entityPhysicalIndex from the ENTITY MIB [RFC4133] in the
pmPhysicalEntity, if supported by the Power Monitor. In case of
Power over Ethernet (if the Power over Ethernet MIB is supported
on the Power Monitor), the Power Monitor pmethPortIndex and
pmethPortGrpIndex must contain the values of pethPsePortIndex
and pethPsePortGroupIndex, respectively. In case of LLDP-MED
<Parello, Claise> Expires June 22, 2011 [Page 5]
Internet-Draft <Energy-aware Networks and Devices MIB> Dec 2010
(if the LLDP-MED MIB is supported on the Power Monitor), the
Power Monitor pmLldpPortNumber must contain the lldpLocPortNum
from the LLDP MIB.
Possible pmName conventions are: textual DNS name, MAC-address
of the device, interface ifName, or a text string uniquely
identifying the Power Monitor. However, if entPhysicalName is
present for the respective pmPhysicalEntity (i.e. if the ENTITY-
MIB is supported), then the pmName SHOULD be identical to the
entPhysicalName. The pmName SHOULD be unique. As an example,
in the case of IP phones, pmName can be the device DNS name,
while in the case of router/switch line cards, the pmName should
contain the entPhysicalName.
To distinguish if a Power Monitor is considered producing,
consuming or metering power, the pmPowerCategory MIB object must
be implemented.
5.2 Power Monitor Meter Domain
Refer to the "Power Monitor Meter Domain" section in [EMAN-FMWK]
for background information.
When a Power Monitor Parent acts as a Power Aggregator or a
Power Proxy, the Power Monitor Parent and its Power Monitor
Child/Children MUST be a member of Power Monitor Meter Domain,
specified by the pmDomainName MIB Object. The pmDomainName,
which is part of the pmTable, is a read-write MIB object.
The Power Monitor Meter Domain SHOULD map 1-1 with a metered or
sub-metered portion of the site. The Power Monitor Meter Domain
MUST be configured on the Power Monitor Parent. The Power
Monitor Children MAY inherit their domain values from the Power
Monitor Parent or the Power Monitor Meter Domain MAY be
configured directly in a Power Monitor Child.
5.3 Power Monitor Parent and Child
Refer to the "Power Monitor Parent and Child" section in [EMAN-
FMWK] for background information. In order to link the Power
Monitor Child and the Power Monitor Parent, the pmParentId is
introduced. When a Power Monitor Parent is a Power Proxy, , the
Power Monitor Parent should enumerate the capabilities it is
providing for the Power Monitor Child. The Power Monitor Child
expresses, thanks to the pmParentCapabilities MIB object, that
it wants its parent to proxy capabilities such as, energy
<Parello, Claise> Expires June 22, 2011 [Page 6]
Internet-Draft <Energy-aware Networks and Devices MIB> Dec 2010
reporting, power state configurations, non physical wake
capabilities (such as WoL)), or any combination of capabilities.
5.4 Power Monitor Context
Refer to the "Power Monitor Context" section in [EMAN-FMWK] for
background information.
A Power Monitor can provide a pmImportance value in the range of
1..100 to help differentiate the use or relative value to the
site. The importance range is from 1 (least important) to 100
(most important). The default importance value is 1.
A Power Monitor can provide a set of pmKeywords. These keywords
are a list of tags that can be used for grouping and summary
reporting within or between Power Monitor Meter Domains.
Additionally, a Power Monitor can provide a pmRoleDescription
string that indicates the purpose the Power Monitor serves in
the network or for the site/business.
6. Structure of the MIB
The primary MIB object in this MIB module is the
EnergyAwareDeviceMIBObject. The pmTable table of
EnergyAwareDeviceMIBObject describes an entity in the network
that is a Power Monitor according the [EMAN-FMWK].
A Power Monitor that implements the EnergyAwareDeviceMIB
contains information describing itself as an entity in the
context of the network (such as its Power Monitor Meter Domain
pmDomainName) and attributes for describing its business context
(such as pmImportance, pmRoleDescription and pmKeywords).
The information in this MIB describes the device itself so that
the device is aware of its context in a communication network
with respect to power. The actual power usage, which is
described in [EMAN-FMWK], is specified in [EMAN-MON-MIB].

8. Security Considerations
Some of the readable objects in these MIB modules (i.e., objects
with a MAX-ACCESS other than not-accessible) may be considered
sensitive or vulnerable in some network environments. It is
thus important to control even GET and/or NOTIFY access to these
objects and possibly to even encrypt the values of these objects
when sending them over the network via SNMP.
There are a number of management objects defined in these MIB
modules with a MAX-ACCESS clause of read-write and/or read-
create. Such objects MAY be considered sensitive or vulnerable
in some network environments. The support for SET operations in
a non-secure environment without proper protection can have a
negative effect on network operations. The following are the
tables and objects and their sensitivity/vulnerability:
. Unauthorized changes to the pmDomainName, pmName,
pmRoleDescription, pmKeywords, and/or pmImportance MAY
disrupt power and energy collection, and therefore any
predefined policies defined in the network.
SNMP versions prior to SNMPv3 did not include adequate security.
<Parello, Claise> Expires June 22, 2011 [Page 18]
Internet-Draft <Energy-aware Networks and Devices MIB> Dec 2010
Even if the network itself is secure (for example, by using
IPsec), there is still no secure control over who on the secure
network is allowed to access and GET/SET
(read/change/create/delete) the objects in these MIB modules.
It is RECOMMENDED that implementers consider the security
features as provided by the SNMPv3 framework (see [RFC3410],
section 8), including full support for the SNMPv3 cryptographic
mechanisms (for authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to
an instance of these MIB modules is properly configured to give
access to the objects only to those principals (users) that have
legitimate rights to GET or SET (change/create/delete) them.
9. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
energyAwareMIB { mib-2 xxx }
Additions to this MIB module are subject to Expert Review
[RFC5226], i.e., review by one of a group of experts designated
by an IETF Area Director. The group of experts MUST check the
requested MIB objects for completeness and accuracy of the
description. Requests for MIB objects that duplicate the
functionality of existing objects SHOULD be declined. The
smallest available OID SHOULD be assigned to a new MIB objects.
The specification of new MIB objects SHOULD follow the structure
specified in Section 6 and MUST be published using a well-
established and persistent publication medium.
