     1. Introduction
     
        The EMAN standards provides network administrators with 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 Electrical
        Equipments (for example network devices and devices attached to
        the network.)
     
        This focus of this MIB module is on monitoring Energy Objects as
        defined in [EMAN-FMWK].  The module addresses Energy Object
        Identification, Energy Object Context, and Energy Object
        Relationships.
     
        Devices and their sub-components are characterized by the power-
        related attributes of a physical entity present in the ENTITY
        MIB [RFC4133].
     
     
     1.1. Energy Management Document Overview
     
        This document specifies the Energy-Aware Networks and Devices
        MIB.  This document is based on the Energy Management Framework
        [EMAN-FMWK] and meets the requirements specified in the Energy
        Management requirements [EMAN-REQ].
     
        The Power and Energy Monitoring MIB [EMAN-MON-MIB] contains the
        Energy Objects for monitoring of Power States, along with the
        Power and Energy consumption of Electrical Objects.  Power State
        monitoring includes: retrieving Power States, Power State
        properties, current Power State, Power State transitions, and
        Power State statistics.  This MIB module provides the detailed
        properties of the Power, Energy, along with optional
        characteristics.

        EDITOR'S NOTE: Replace characteristics with consensus term when
        defined. This is electrical qualities or characteristics.
     
        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.
     
     
     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. Requirements and Use Cases
     
        Requirements for power and energy monitoring for networking
        devices are specified in [EMAN-REQ].  The requirements in [EMAN-
        REQ] include communications network devices, such as switches,
        routers, and various connected endpoints and Electrical
        Equipments.
     
        The use cases for this MIB are specified in the EMAN
        applicability statement document [EMAN-AS].
     
        EDITOR'S NOTE: say a few words about the use cases when we will
        have a stable version of the EMAN applicability statement
        document.
     
        Accordingly, the scope of the MIB module in this document is in
        accordance to the requirements specified in [EMAN-REQ] and the
        use cases in [EMAN-AS].

     Internet-Draft <Energy-aware Networks and Devices MIB> Oct 2011
     
     
        As displayed in figure 1, there are six different logical groups
        of MIB objects in the ENERGY-AWARE-MIB module:
     
        1) The Energy Object Identification. See Section 5.1 "Energy
           Object Identification"
        2) The Context Information. See Section 5.2 "Energy Object
           Context"
        3) The links to other MIB modules. See Section 5.3 "Links to
           other Identifiers"
        4) The Energy Object Child Relationships specific information.
           See Section 5.4 "Child: Energy Objects Relationship."
        5) The Energy Object Parent Relationships specific information.
           See Section 5.5 "Parent: Energy Objects Relationship."
        6) The Energy Object Identity Persistence. See Section 5.6
           "Energy Object Identity Persistence"
     
     
     5.1 Energy Object Identification
     
        Refer to the "Energy Object Information" section in [EMAN-FMWK]
        for background information about Energy Objects.
     
        Every Energy Object MUST support the unique index,
        entPhysicalIndex, from the ENTITY MIB [RFC4133], which is used
        as index for the primary Energy Object information in the
        ENERGY-AWARE-MIB module eoTable table.
     
        The ENERGY-AWARE-MIB MIB module, specified in this document
        requires the implementation of some managed objects in the
        ENTITY MIB [RFC4133].
     
        Other ENTITY MIB managed objects MAY be implemented.
     
        Every Energy Object MUST have a printable name. Energy Objects
        MUST implement the entPhysicalName object specified in the
        ENTITY-MIB, which must contain the Energy Object name.
     
        By the [RFC4133] definition, the entPhysicalUris contains a
        white space separated list of  Uniform Resource Identifier
        (s)(URIs).  For the ENERGY-AWARE-MIB compliance, every Energy
        Object instance MUST implement the entPhysicalUris from the
        ENTITY MIB [RFC4133].  The entPhysicalUris MUST contain the
        Energy Object UUID, according to [RFC4122].
     
        As displayed in [RFC4122], the following is an example of the
        string representation of a UUID as a URN: urn:uuid:f81d4fae-
        7dec-11d0-a765-00a0c91e6bf6.

     Internet-Draft <Energy-aware Networks and Devices MIB> Oct 2011
     
        Other ENTITY MIB managed objects, next to entPhysicalIndex,
        entPhysicalName, and entPhysicalUris, MAY be implemented.
     
        When a Energy Object Parent acts as a Power Aggregator or a
        Power Proxy, the Energy Object Parent and its Energy Object
        Child/Children MUST be members of the same Energy Management
        Domain, specified by the eoDomainName MIB Object.
     
        Each Energy Object MUST belong to a single Energy Management
        Domain or in other words, a Energy Object cannot belong to more
        than one Energy Management Domain.  Refer to the "Energy
        Management Domain" section in [EMAN-FMWK] 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 site.  The Energy Management Domain MUST be configured on
        the Energy Object Parent.  The Energy Object Children MAY
        inherit their domain parameters from the Energy Object Parent or
        the Energy Management Domain MAY be configured directly in a
        Energy Object Child.
     
        The eoMgmtMacAddress, eoMgmtAddress, eoMgmtAddressType, and
        eoMgmtDNSName MIB objects SHOULD be implemented for Energy
        Object Children, and MAY be implemented for Energy Object
        Parents.
     
     
     
     5.2 Energy Object Context
     
        Refer to the "Energy Object Context" section in [EMAN-FMWK] for
        background information.
     
        A Energy Object can provide a eoImportance value 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.
     
        A 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.
     
        Additionally, a Energy Object can provide a eoRoleDescription
        string that indicates the purpose the Energy Object serves in
        the network or for the site/business.

     5.3 Links to Other Identifiers
     
        While the entPhysicalIndex is the primary index for all MIB
        objects in the ENERGY-AWARE-MIB module, the Energy Management
        Systems (EnMS) must be able to make the link with the
        identifier(s) in other supported MIB modules.
     
        The Energy Object eoethPortIndex and eoethPortGrpIndex MUST
        contain the values of pethPsePortIndex and pethPsePortGroupIndex
        from the Power over Ethernet MIB [RFC3621], if the Power over
        Ethernet MIB is supported by the Energy Object SNMP agent.
     
        The Energy Object eoLldpPortNumber MUST contain the
        lldpLocPortNum from the LLDP MIB [LLDP-MIB], if the LLDP-MED MIB
        is supported on the Energy Object SNMP agent.
     
        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-AWARE-MIB 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 any of these two MIB modules for the
        Energy Objects.  However, in situation where any of these two
        MIB modules is implemented, the EnMS must be able to correlate
        the instances in the different MIB modules.
     
        The eoAlternateKey alternate key object specifies a manufacturer
        defined string that can be used to identify the Energy Object.
        Since 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 NULL should be returned.
     
     
     5.4 Child: Energy Object Relationships
     
        Refer to the "Energy Object Parent and Child" section in [EMAN-
        FMWK] for background information.
     
        In order to link the Energy Object Child and the Energy Object
        Parent, multiple objects are introduced in the MIB module.
        Depending on the Energy Object Relationship type, the following
        objects are appropriate:

         Metering Relationship         ->   eoMeteredBy
     
         Power Source Relationship     ->   eoPoweredBy
     
         Dependency Relationship       ->   eoDependentOf
     
         Aggregation Relationship      ->   eoAggregatedBy
     
          Proxy Relationship            ->   eoProxyBy,
                                        ->   eoParentProxyAbilities
     
        Each object contains the list of Energy Object Parent UUIDs for
        the specific Energy Object Relationship type.  The UUIDs MUST
        comply to the RFC 4122 specifications.  The object contains URIs
        and, therefore, the syntax of this object must conform to RFC
        3986 [RFC3986], section 2.  Multiple URIs may be present and are
        separated by white space characters.  Leading and trailing white
        space characters are ignored.
     
        For example, if an Energy Object Child is powered by two power
        sources, eoPoweredBy would contain the two power sources UUIDs,
        separated by a space: "urn:uuid:f81d4fae-7dec-11d0-a765-
        00a0c91e6bf6 urn:uuid:abcdec11-7abc-23e1-b876-00a0c91e6bf8".
     
        The eoParentProxyAbilities object is specific to the Proxy
        Relationship.  This object describes the capabilities of the
        Energy Object Parent for the Energy Object Child represented by
        the entPhysicalIndex. The possible capabilities are: report,
        configuration, and/or wakeonlan.  This object only applies to an
        Energy Object Child.
     
        If the Energy Object is not an Energy Object Child, or if the
        Energy Object doesn't have a Energy Object Relationship, the
        eoMeteredBy, eoPoweredBy, eoDependentOf, eoAggregatedBy,
        eoProxyBy, and eoParentProxyAbilities objects are not
        instantiated.  A zero length octet string MAY also be returned
        in this case.
     
        The Energy Object Child can indicate that it wants its Energy
        Object Parent to proxy capabilities such as, energy reporting,
        power state configurations, non physical wake capabilities (such
        as Wake-on-LAN)), or any combination of capabilities.  These
        capabilities are indicated in the eoParentProxyAbilities object.
        In the case of Energy Object Parent, the eoParentProxyAbilities
        MUST be set to "none" (0).

        Since the communication between the Energy Object Parent and
        Energy Object Child may not be via SNMP (as defined in EMAN-
        FMWK), a Energy Object Child can have additional MIB objects
        that can be used for easier identification by the EnMS. The
        optional objects eoMgmtMacAddress, eoMgmtAddressType
        eoMgmtDNSName can be used to help identify the relationship
        between the child 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).
     
        The eoMeteredBy, eoPoweredBy, eoDependentOf, eoAggregatedBy,
        eoProxyBy, and eoParentProxyAbilities implementations are
        optional.
     
     
     
     5.5 Parent: Energy Object Relationships
     
        When the Energy Object is an Energy Object Parent, the
        eoChildrenList object represents the list of Energy Object
        Child(ren) UUIDs.  This UUID list will help in the network
        discovery of Energy Objects, using the Energy Object Parent as
        entry points.
     
        eoChildrenList has the same format as the eoMeteredBy,
        eoPoweredBy, eoDependentOf, eoAggregatedBy, and eoProxyBy. The
        UUIDs MUST comply to the RFC 4122 specifications.  The UUIDs
        MUST comply to the RFC 4122 specifications.  The eoChildrenList
        object contains URIs and, therefore, the syntax of this object
        must conform to RFC 3986 [RFC3986], section 2.  Multiple URIs
        may be present and are separated by white space characters.
        Leading and trailing white space characters are ignored.
     
        If the Energy Object is not an Energy Object Parent, the
        eoChildrenList objects is not instantiated.  A zero length octet
        string MAY also be returned in this case.
     
        The eoChildrenList implementation is optional.
     
     
     
     5.6 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.  Therefore, a specific MIB object, the
        eoTablePersistence, enables and disables the persistence
        globally for all Energy Objects information in the ENERGY-AWARE-
        MIB module.
     
     
     6. Structure of the MIB
     
        The primary MIB object in this MIB module is the energyAwareMIB
        Object.  The eoTable table of energyAwareMIB Object describes an
        entity in the network that is a Energy Object according the
        [EMAN-FMWK].

     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 eoDomainName, entPhysicalName,
             eoRoleDescription, eoKeywords, and/or eoImportance 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.
        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).
     
     
     
     <Parello, Claise>       Expires April 30, 2012           [Page 29]


     Internet-Draft <Energy-aware Networks and Devices MIB> Oct 2011
     
        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.
