    SYNTAX Integer32 (0..2147483647)

PhysicalClass ::= TEXTUAL-CONVENTION
    STATUS            current
    DESCRIPTION            "An enumerated value which provides an indication of the
            general hardware type of a particular physical entity.
            There are no restrictions as to the number of
            entPhysicalEntries of each entPhysicalClass, which must be
            instantiated by an agent.

            The enumeration 'other' is applicable if the physical entity
            class is known, but does not match any of the supported
            values.

            The enumeration 'unknown' is applicable if the physical
            entity class is unknown to the agent.

            The enumeration 'chassis' is applicable if the physical
            entity class is an overall container for networking
            equipment.  Any class of physical entity, except a stack,
            may be contained within a chassis; and a chassis may only
            be contained within a stack.


            The enumeration 'backplane' is applicable if the physical
            entity class is some sort of device for aggregating and
            forwarding networking traffic, such as a shared backplane in
            a modular ethernet switch.  Note that an agent may model a
            backplane as a single physical entity, which is actually
            implemented as multiple discrete physical components (within
            a chassis or stack).

            The enumeration 'container' is applicable if the physical
            entity class is capable of containing one or more removable
            physical entities, possibly of different types.  For
            example, each (empty or full) slot in a chassis will be
            modeled as a container.  Note that all removable physical
            entities should be modeled within a container entity, such
            as field-replaceable modules, fans, or power supplies.  Note
            that all known containers should be modeled by the agent,
            including empty containers.

            The enumeration 'powerSupply' is applicable if the physical
            entity class is a power-supplying component.

            The enumeration 'fan' is applicable if the physical entity
            class is a fan or other heat-reduction component.

            The enumeration 'sensor' is applicable if the physical
            entity class is some sort of sensor, such as a temperature
            sensor within a router chassis.

            The enumeration 'module' is applicable if the physical
            entity class is some sort of self-contained sub-system.  If
            the enumeration 'module' is removable, then it should be
            modeled within a container entity, otherwise it should be
            modeled directly within another physical entity (e.g., a
            chassis or another module).

            The enumeration 'port' is applicable if the physical entity
            class is some sort of networking port, capable of receiving
            and/or transmitting networking traffic.

            The enumeration 'stack' is applicable if the physical entity
            class is some sort of super-container (possibly virtual),
            intended to group together multiple chassis entities.  A
            stack may be realized by a 'virtual' cable, a real
            interconnect cable, attached to multiple chassis, or may in
            fact be comprised of multiple interconnect cables.  A stack
            should not be modeled within any other physical entities,
            but a stack may be contained within another stack.  Only
            chassis entities should be contained within a stack.


            The enumeration 'cpu' is applicable if the physical entity
            class is some sort of central processing unit.

entPhysicalParentRelPos OBJECT-TYPE
    SYNTAX      Integer32 (-1..2147483647)

    STATUS      current
    DESCRIPTION            "An indication of the relative position of this 'child'
            component among all its 'sibling' components.  Sibling
            components are defined as entPhysicalEntries that share the
            same instance values of each of the entPhysicalContainedIn
            and entPhysicalClass objects.

            An NMS can use this object to identify the relative ordering
            for all sibling components of a particular parent
            (identified by the entPhysicalContainedIn instance in each
            sibling entry).

            If possible, this value should match any external labeling
            of the physical component.  For example, for a container
            (e.g., card slot) labeled as 'slot #3',
            entPhysicalParentRelPos should have the value '3'.  Note
            that the entPhysicalEntry for the module plugged in slot 3
            should have an entPhysicalParentRelPos value of '1'.

            If the physical position of this component does not match
            any external numbering or clearly visible ordering, then
            user documentation or other external reference material
            should be used to determine the parent-relative position.
            If this is not possible, then the agent should assign a
            consistent (but possibly arbitrary) ordering to a given set
            of 'sibling' components, perhaps based on internal
            representation of the components.


            If the agent cannot determine the parent-relative position
            for some reason, or if the associated value of
            entPhysicalContainedIn is '0', then the value '-1' is
            returned.  Otherwise, a non-negative integer is returned,
            indicating the parent-relative position of this physical
            entity.

            Parent-relative ordering normally starts from '1' and
            continues to 'N', where 'N' represents the highest
            positioned child entity.  However, if the physical entities
            (e.g., slots) are labeled from a starting position of zero,
            then the first sibling should be associated with an
            entPhysicalParentRelPos value of '0'.  Note that this
            ordering may be sparse or dense, depending on agent
            implementation.

            The actual values returned are not globally meaningful, as
            each 'parent' component may use different numbering
            algorithms.  The ordering is only meaningful among siblings
            of the same parent component.

            The agent should retain parent-relative position values
            across reboots, either through algorithmic assignment or use
            of non-volatile storage.

            set to a zero-length string instead.

            Note that implementations that can correctly identify the
            serial numbers of all installed physical entities do not
            need to provide write access to the entPhysicalSerialNum

            for the entPhysicalSerialNum strings are not required to
            implement write access for this object.

            Not every physical component will have a serial number, or

            A compliant SNMP agent may wish to conserve naming scopes by

            'repeater1' may be part of the main naming scope, but at
            least one additional community string is needed to represent
            'bridge2' and 'repeater2'.

            Logical entities 'bridge1' and 'repeater1' would be
            represented by sysOREntries associated with the 'default'
            naming scope.

            An agent should limit the number and nature of entries in

            closest to the root of a particular containment tree, should

            For example, suppose a bridge is realized on a particular

            were utilizing ports on this module, then mappings between

            Also, in the case of a single backplane repeater, a mapping

entAliasLogicalIndexOrZero OBJECT-TYPE

    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION            "The value of this object identifies the logical entity
            that defines the naming scope for the associated instance
            of the 'entAliasMappingIdentifier' object.

            If this object has a non-zero value, then it identifies the
            logical entity named by the same value of entLogicalIndex.

            If this object has a value of zero, then the mapping between
            the physical component and the alias identifier for this
            entAliasMapping entry is associated with all unspecified
            logical entities.  That is, a value of zero (the default
            mapping) identifies any logical entity that does not have
            an explicit entry in this table for a particular
            entPhysicalIndex/entAliasMappingIdentifier pair.

            For example, to indicate that a particular interface (e.g.,
            physical component 33) is identified by the same value of
            ifIndex for all logical entities, the following instance
            might exist:

                    entAliasMappingIdentifier.33.0 = ifIndex.5

            In the event an entPhysicalEntry is associated differently
            for some logical entities, additional entAliasMapping
            entries may exist, e.g.:


                    entAliasMappingIdentifier.33.0 = ifIndex.6
                    entAliasMappingIdentifier.33.4 =  ifIndex.1
                    entAliasMappingIdentifier.33.5 =  ifIndex.1
                    entAliasMappingIdentifier.33.10 = ifIndex.12

            Note that entries with non-zero entAliasLogicalIndexOrZero
            index values have precedence over zero-indexed entries.  In
            this example, all logical entities except 4, 5, and 10,
            associate physical entity 33 with ifIndex.6.

entAliasMappingIdentifier OBJECT-TYPE
    SYNTAX      RowPointer
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION            "The value of this object identifies a particular conceptual
            row associated with the indicated entPhysicalIndex and
            entLogicalIndex pair.

            Because only physical ports are modeled in this table, only
            entries that represent interfaces or ports are allowed.  If
            an ifEntry exists on behalf of a particular physical port,
            then this object should identify the associated 'ifEntry'.
            For repeater ports, the appropriate row in the
            'rptrPortGroupTable' should be identified instead.

            For example, suppose a physical port was represented by
            entPhysicalEntry.3, entLogicalEntry.15 existed for a
            repeater, and entLogicalEntry.22 existed for a bridge.  Then
            there might be two related instances of
            entAliasMappingIdentifier:
               entAliasMappingIdentifier.3.15 == rptrPortGroupIndex.5.2
               entAliasMappingIdentifier.3.22 == ifIndex.17
            It is possible that other mappings (besides interfaces and
            repeater ports) may be defined in the future, as required.

            Bridge ports are identified by examining the Bridge MIB and
            appropriate ifEntries associated with each 'dot1dBasePort',
            and are thus not represented in this table.

entConfigChange NOTIFICATION-TYPE
    STATUS             current
    DESCRIPTION            "An entConfigChange notification is generated when the value
            of entLastChangeTime changes.  It can be utilized by an NMS
            to trigger logical/physical entity table maintenance polls.

            An agent should not generate more than one entConfigChange
            'notification-event' in a given time interval (five seconds
            is the suggested default).  A 'notification-event' is the
            transmission of a single trap or inform PDU to a list of
            notification destinations.

            If additional configuration changes occur within the
            throttling period, then notification-events for these
            changes should be suppressed by the agent until the current
            throttling period expires.  At the end of a throttling
            period, one notification-event should be generated if any
            configuration changes occurred since the start of the
            throttling period.  In such a case, another throttling
            period is started right away.

            An NMS should periodically check the value of
            entLastChangeTime to detect any missed entConfigChange
            notification-events, e.g., due to throttling or transmission
            loss.
