    SYNTAX OCTET STRING (SIZE(0..32)) -- empty string or SnmpEngineID

PhysicalClass ::= TEXTUAL-CONVENTION
    STATUS            deprecated
    DESCRIPTION
            "Starting with version 4 of the ENTITY-MIB, this TC is
            deprecated, and the usage of the IANAPhysicalClass TC from
            the IANA-ENTITY-MIB is recommended instead.

            An enumerated value that 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; 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

Top      Up      ToC       Page 21 
            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."

    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.

Top      Up      ToC       Page 25 
            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."

            'bridge2' and 'repeater2'.

            Logical entities 'bridge1' and 'repeater1' would be

            "This table contains zero or more rows of logical entity to
            physical equipment associations.  For each logical entity
            known by this agent, there are zero or more mappings to the
            physical resources, which are used to realize that logical
            entity.

            An agent should limit the number and nature of entries in
            this table such that only meaningful and non-redundant
            information is returned.  For example, in a system that
            contains a single power supply, mappings between logical
            entities and the power supply are not useful and should not
            be included.

            Also, only the most appropriate physical component, which is
            closest to the root of a particular containment tree, should
            be identified in an entLPMapping entry.

            For example, suppose a bridge is realized on a particular
            module, and all ports on that module are ports on this
            bridge.  A mapping between the bridge and the module would
            be useful, but additional mappings between the bridge and
            each of the ports on that module would be redundant (because
            the entPhysicalContainedIn hierarchy can provide the same
            information).  On the other hand, if more than one bridge
            were utilizing ports on this module, then mappings between
            each bridge and the ports it used would be appropriate.

Top      Up      ToC       Page 39 
            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.33.10 = 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

            Because only physical ports are modeled in this table, only

            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

            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'

            If additional configuration changes occur within the
