        TO DO
     
          . The roles/capabilities that the Power Monitor Parent have
             with Power Monitor Child(ren) are described in [POWER-MON-
             ARCH]:
                 1. Monitoring (only reporting)
                 2. Configuration power state
                 3. Configuration: power
             Example: on a PC, we can set power level without knowing
             the power. A solution must be specified in this draft.
             We have to find a way to model this role in this MIB
             module.  Bitmap is just one example.
     
     
     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
        [POWER-MON-ARCH], which in turn, is based on the Power
        Monitoring Requirements [POWER-MON-REQ] .
     
        This module's special focus is on monitoring energy-aware
        networks and devices.  The module addresses device
        identification, context information, and potential 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.
     
     
     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 [POWER-MON-REQ].  The requirements in
        [POWER-MON-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 [POWER-MON-REQ].
     
     
     4. Terminology
     
        The definitions of basic terms like Power Monitor, Power Monitor
        Parent, Power Monitor Child, Power Monitor Meter Domain, Power
        Level, and Manufacturer Power Level can be found in the Power
        Management Architecture [POWER-MON-ARCH].
     
     
     
     5. Architecture Concepts Applied to the MIB Module
     
        This section describes the basic concepts specified in the Power
        Monitor Architecture [POWER-MON-ARCH], 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 [POWER-MON-ARCH].
     
     
     
     5.1 Power Monitor Information
     
        Refer to the "Power Monitor Information" section in [POWER-MON-
        ARCH] for background information.  An energy aware device is
        considered an instance of a power monitor as defined in the
        [POWER-MON-ARCH].
     
        The Power Monitor information is specified in the MIB module
        primary table, i.e. the pmTable.  Every Power Monitor SHOULD
     
     
     
     
     <Parello, Claise>       Expires April 16, 2011            [Page 5]


     Internet-Draft <Energy-aware Networks and Devices MIB>  Oct 2010
     
        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
        (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 [POWER-MON-
        ARCH] for background information.
     
        Each Power Monitor MUST be a member of a Power Monitor Meter
        Domain, specified by the pmDomainName MIB Object.  The
        pmDomainName, which is part of the pmTable, is a read-write MIB
        object.

     Internet-Draft <Energy-aware Networks and Devices MIB>  Oct 2010
     
       5.3 Power Monitor Parent and Child
     
        Refer to the "Power Monitor Parent and Child" section in [POWER-
        MON-ARCH] for background information.  In order to link the
        Power Monitor Child and the Power Monitor Parent, the pmParentId
        is introduced.
     
     
       5.4 Power Monitor Context
     
        Refer to the "Power Monitor Context" section in [POWER-MON-ARCH]
        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 [POWER-MON-ARCH].
     
        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 [POWER-MON-ARCH], is specified in [POWER-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.
        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

     Internet-Draft <Energy-aware Networks and Devices MIB>  Oct 2010
     
        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.
