1. Introduction
The Energy Management (EMAN) standards provide a specification for
Energy Management. This document defines a subset of a Management
Information Base (MIB) for use with network management protocols for
Energy monitoring of network devices and devices attached to the
network and possibly extending to devices in the industrial
automation setting with a network interface.
The focus of the MIB module specified in this document is on the
identification of Energy Objects and reporting the context and
relationships of Energy Objects as defined in [RFC 7326]. The module
addresses Energy Object identification, Energy Object context, and
Energy Object relationships.
1.1. Energy Management Document Overview
This document specifies the Energy Object Context (ENERGY-OBJECT-
CONTEXT-MIB) and IANA Energy Relationship (IANA-ENERGY-RELATION-MIB)
modules. The Energy Object Context MIB module specifies MIB objects
for identification of Energy Objects, and reporting context and
relationship of an Energy Object. The IANA Energy Relationship MIB
module specifies the first version of the IANA-maintained definitions
of relationships between Energy Objects.
Parello, et al. Standards Track PAGE 2
RFC 7461 Energy Object Context MIB March 2015
Firstly, to illustrate the importance of energy monitoring in
networks and, secondly, to list some of the important areas to be
addressed by the Energy Management Framework [RFC 7326], several use
cases and network scenarios are presented in the EMAN applicability
statement document [EMAN-AS]. In addition, for each scenario, the
target devices for energy management, and how those devices powered
and metered are also presented. To address the network scenarios,
requirements for power and energy monitoring for networking devices
are specified in [RFC 6988]. Based on the requirements in [RFC 6988],
[RFC 7326] presents a solution approach.
Accordingly, the scope of the MIB modules in this document is in
accordance to the requirements specified in [RFC 6988] and the
concepts from [RFC 7326].
This document is based on the Energy Management Framework [RFC 7326]
and meets the requirements on identification of Energy Objects and
their context and relationships as specified in the Energy Management
requirements document [RFC 6988].
A second MIB module meeting the EMAN requirements [RFC 6988] the
Monitoring and Control MIB for Power and Energy [RFC 7460], monitors
the Energy Objects for Power States, for the Power and Energy
consumption. Power State monitoring includes: retrieving Power
States, Power State properties, current Power State, Power State
transitions, and Power State statistics. In addition, this MIB
module provides the Power Characteristics properties of the Power and
Energy, along with optional characteristics.
The applicability statement document [EMAN-AS] provides the list of
use cases, describes the common aspects between existing Energy
standards and the EMAN standard, and shows how the EMAN framework
relates to other frameworks.
1.2. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in

Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC 3410].
Parello, et al. Standards Track PAGE 3
RFC 7461 Energy Object Context MIB March 2015
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 [RFC 2578], STD 58, RFC 2579 [RFC 2579] and STD 58, RFC 2580
[RFC 2580].

4. Architecture Concepts Applied to the MIB Module
This section describes the basic concepts specified in the Energy
Management Framework [RFC 7326], with specific information related to
the MIB modules specified in this document.
Parello, et al. Standards Track PAGE 4
RFC 7461 Energy Object Context MIB March 2015
The Energy Object Context (ENERGY-OBJECT-CONTEXT-MIB) MIB module in
this document specifies MIB objects for the identification of Energy
Objects and reporting context and relationship of an Energy Object.
The managed objects are contained in two tables: eoTable and
eoRelationTable.
The first table, eoTable, focuses on the link to the other MIB
modules, on identification, and on the context of the Energy Object.
The second table, eoRelationTable, specifies the relationships
between Energy Objects. This is a simplified representation of the
relationship between Energy Objects.
A "smidump-style" tree presentation of the MIB modules contained in
the document is presented. The meaning of the three symbols in is a
compressed representation of the object's MAX-ACCESS clause, which
may have the following values:
"not-accessible"->"---"
"accessible-for-notify"->"--n"
"read-only"->"r-n"
"read-write"->"rwn"

The following Unified Modeling Language (UML) diagram illustrates the
relationship of the MIB objects in the eoTable, eoRelationTable, and
ENTITY-MIB. The MIB objects describe the identity, context, and
relationship of an Energy Object. The UML diagram, furthermore,
contains objects from the ENTITY-MIB [RFC 6933].

Figure 1: MIB Objects Grouping
Parello, et al. Standards Track PAGE 7
RFC 7461 Energy Object Context MIB March 2015
As displayed in Figure 1, the MIB objects can be classified in
different logical grouping of MIB objects.
1) The Energy Object Identification. See Section 5.1 "Energy Object
Identification". Devices and their sub-components are
characterized by the power-related attributes of a physical entity
present in the ENTITY-MIB [RFC 6933].
2) The Context Information. See Section 4.1 "Energy Object Context".
3) The links to other MIB modules. See Section 4.3 "Links to Other
Identifiers".
4) The Energy Object Relationships specific information. See Section
4.4 "Energy Object Relationships".
5) The Energy Object Identity Persistence. See Section 4.5 "Energy
Object Identity Persistence".
4.1. Energy Object Identification
Refer to the "Identification" section in [RFC 7326] for background
information about Energy Objects.
Every Energy Object MUST implement the unique index,
entPhysicalIndex, entPhysicalName, entPhysicalClass, and
entPhysicalUUID from the ENTITY-MIB [RFC 6933]. Module Compliance
with respect to entity4CRCompliance of ENTITY-MIB MUST be supported,
which requires a limited number of objects supported
(entPhysicalIndex, entPhysicalName, entPhysicalClass, and
entPhysicalUUID). entPhysicalIndex is used as index for the Energy
Object in the ENERGY-OBJECT-CONTEXT-MIB module. Every Energy Object
MUST have a printable name assigned to it. Energy Objects MUST
implement the entPhysicalName object specified in the ENTITY-MIB
[RFC 6933], which must contain the Energy Object name.
For the ENERGY-OBJECT-CONTEXT-MIB compliance, every Energy Object
instance MUST implement the entPhysicalUUID from the ENTITY-MIB
[RFC 6933].
As displayed in [RFC 4122], the following is an example of the string
representation of a Universally Unique Identifier (UUID) as a URN:
urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6.
For example, to understand the relationship between Energy Object
Components and Energy Objects, the ENTITY-MIB physical containment
tree [RFC 6933] MUST be implemented.
Parello, et al. Standards Track PAGE 8
RFC 7461 Energy Object Context MIB March 2015
A second example deals with one of the ENTITY-MIB extensions: if the
Energy Object temperature is required, the managed objects from the
ENTITY-SENSOR-MIB [RFC 3433] should be supported.
Each Energy Object MUST belong to a single Energy Management Domain
or in other words, an Energy Object cannot belong to more than one
Energy Management Domain. Refer to the "Context: Domain" section in
[RFC 7326] for background information. The eoDomainName, which is an
element of the eoTable, is a read-write MIB object. The Energy
Management Domain should map 1:1 with a metered or sub-metered
portion of the network. The Energy Management Domain MUST be
configured on the Energy Object. The Energy Object MAY inherit some
of the domain parameters (possibly domain name, some of the context
information such as role or keywords, importance) from the Energy
Object or the Energy Management Domain MAY be configured directly in
an Energy Object.
When an Energy Object acts as a Power Aggregator, the Energy Objects
for which Power should be aggregated MUST be members of the same
Energy Management Domain, specified by the eoDomainName MIB Object.
4.2. Energy Object Context
Refer to the "Context: Domain" section in [RFC 7326] for background
information.
An Energy Object must provide a value for eoImportance in the range
of 1-100 to help differentiate the use or relative value of the
device. The importance range is from 1 (least important) to 100
(most important). The default importance value is 1.
An Energy Object can provide a set of eoKeywords. These keywords are
a list of tags that can be used for grouping and summary reporting
within or between Energy Management Domains.
An Energy Object can have Power Interfaces and those interfaces can
be classified as Power Inlet, Power Outlet, or both.
An Energy Object can be classified based on the physical properties
of the Energy Object. That Energy Object can be classified as
consuming power or supplying power to other devices or that Energy
Object can perform both of those functions and finally, an Energy
Object can be a passive meter.
Additionally, an Energy Object can provide an eoRoleDescription
string that indicates the purpose the Energy Object serves in the
network.
Parello, et al. Standards Track PAGE 9
RFC 7461 Energy Object Context MIB March 2015
4.3. Links to Other Identifiers
While the entPhysicalIndex is the primary index for all MIB objects
in the ENERGY-OBJECT-CONTEXT-MIB module, the Energy Management
Systems (EnMS) must be able to make the link with the identifier(s)
in other supported MIB modules.
If the Energy Object is a Power over Ethernet (PoE) port, and if the
Power over Ethernet MIB [RFC 3621] is supported by the SNMP agent
managing the Energy Object, then the Energy Objects eoethPortIndex
and eoethPortGrpIndex MUST contain the corresponding values of
pethPsePortIndex and pethPsePortGroupIndex [RFC 3621].
If the LLDP-MED MIB [LLDP-MIB] is supported by the Energy Object SNMP
agent, then the Energy Object eoLldpPortNumber MUST contain the
corresponding lldpLocPortNum from the LLDP MIB.
The intent behind the links to the other MIB module identifier(s) is
to correlate the instances in the different MIB modules. This will
allow the ENERGY-OBJECT-CONTEXT-MIB module to reference other MIB
modules in cases where the Power over Ethernet and the LLDP MIB
modules are supported by the SNMP agent. Some use cases may not
implement either of these two MIB modules for the Energy Objects.
However, in situations where either of these two MIB modules are
implemented, the EnMS must be able to correlate the instances in the
different MIB modules.
The eoAlternateKey object specifies an alternate key string that can
be used to identify the Energy Object. Since an EnMS may need to
correlate objects across management systems, this alternate key is
provided to facilitate such a link. This optional value is intended
as a foreign key or alternate identifier for a manufacturer or EnMS
to use to correlate the unique Energy Object Id in other systems or
namespaces. If an alternate key is not available or is not
applicable, then the value is the zero-length string.
An Energy Object can have additional MIB objects that can be used for
easier identification by the EnMS. The optional objects
eoMgmtMacAddress, eoMgmtAddressType, and eoMgmtDNSName can be used to
help identify the relationship between the Energy Objects and other
NMS objects. These objects can be used as an alternate key to help
link the Energy Object with other keyed information that may be
stored within the EnMS(s). For the optional objects that may not be
included in some vendor implementations, the expected behavior when
those objects are polled is a response noSuchInstance.
Parello, et al. Standards Track PAGE 10
RFC 7461 Energy Object Context MIB March 2015
4.4. Energy Object Relationships
Refer to the "Relationships" section in [RFC 7326] for the definition
and background information. In order to link two Energy Objects, a
separate table (eoRelationTable) has been introduced in this MIB
module.
Each Energy Object can have one or more Energy Object relationships
with other Energy Objects. The relationship between Energy Objects
is specified in eoRelationTable. The relationship between the Energy
Objects is specified with the entPhysicalIndex of the Energy Object
and the UUID of the remote Energy Object. The UUID MUST comply to
the RFC 4122 specifications. It is important to note that it is
possible that an Energy Object may not have an Energy Object
relationship with other Energy Objects.
The following relationships between Energy Objects have been
considered in the eoRelationTable.
Metering Relationship -> meteredBy / metering
Power Source Relationship -> poweredBy / powering
Aggregation Relationship -> aggregatedBy / aggregating
Energy Object B has a "meteredBy" relationship with Energy Object A,
if the energy consumption of Energy Object B is measured by Energy
Object A. Equivalently, it is possible to indicate that Energy
Object A has a "metering" relationship with Energy Object B.
Energy Object B has a "poweredBy" relationship with Energy Object A,
if the power source of Energy Object B is Energy Object A.
Equivalently, it is possible to indicate that Energy Object A has a
"powering" relationship with Energy Object B.
Energy Object B has "aggregatedBy" relationship with Energy Object A,
if Energy Object A is an aggregation point for energy usage of Energy
Object B. Equivalently, it is possible to indicate that Energy
Object A has "aggregating" relationship with Energy Object B.
The IANA-ENERGY-RELATION-MIB module in Section 5 below specifies the
first version of the IANA-maintained definitions of relationships.
This way, for Energy Relationships, new textual conventions can be
specified, without updating the primary Energy Object Context MIB
module.
Parello, et al. Standards Track PAGE 11
RFC 7461 Energy Object Context MIB March 2015
4.5. Energy Object Identity Persistence
In some situations, the Energy Object identity information should be
persistent even after a device reload. For example, in a static
setup where a switch monitors a series of connected PoE phones, there
is a clear benefit for the EnMS if the Energy Object Identification
and all associated information persist, as it saves a network
discovery. However, in other situations, such as a wireless access
point monitoring the mobile user PCs, there is not much advantage to
persist the Energy Object Information. The identity information of
an Energy Object should be persisted and there is value in the
writable MIB objects persisted.

6. Security Considerations
There are a number of management objects defined in this MIB module
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 opens devices to attack. These
are the tables and objects and their sensitivity/vulnerability:
Unauthorized changes to the eoDomainName, entPhysicalName,
eoRoleDescription, eoKeywords, eoImportance, eoAlternateKey,
eoRelationID, eoRelationship, eoRelationStatus, and/or
eoRelationStorageType MAY disrupt power and energy collection, and
therefore any predefined policies defined in the network.
Parello, et al. Standards Track PAGE 27
RFC 7461 Energy Object Context MIB March 2015
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
there is no control as to who on the secure network is allowed to
access and GET/SET (read/change/create/delete) the objects in this
MIB module.
Implementations SHOULD provide the security features described by the
SNMPv3 framework (see [RFC 3410]), and implementations claiming
compliance to the SNMPv3 standard MUST include full support for
authentication and privacy via the User-based Security Model (USM)
[RFC 3414] with the AES cipher algorithm [RFC 3826]. Implementations
MAY also provide support for the Transport Security Model (TSM)
[RFC 5591] in combination with a secure transport such as SSH
[RFC 5592] or TLS/DTLS [RFC 6353].
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 this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
In certain situations, energy and power monitoring can reveal
sensitive information about individuals' activities and habits.
Implementors of this specification should use appropriate privacy
protections as discussed in Section 9 of RFC 6988 and monitoring of
individuals and homes should only occur with proper authorization.
7. IANA Considerations
The MIB modules in this document use the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER Value
---------- -----------------------
energyObjectContextMIB { mib-2 231 }
This document defines the first version of the IANA-maintained IANA-
ENERGY-RELATION-MIB module, which allows new definitions of
relationships between Energy Objects.
A Specification Required as defined in [RFC 5226] is REQUIRED for each
modification of the energy relationships.
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry.
