DESCRIPTION
"An arbitrary value which uniquely identifies the physical

values for different physical entities are not necessarily
contiguous."
SYNTAX INTEGER (1..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
it 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."

An agent should set this object to a enterprise-specific
registration identifier value indicating the specific
equipment type in detail. The associated instance of
entPhysicalClass is used to indicate the general type of

this physical entity is not contained in any other physical
entity. Note that the set of 'containment' relationships
define a strict hierarchy; that is, recursion is not
allowed.
In the event a physical entity is contained by more than one

should identify the containing entity with the lowest value
of entPhysicalIndex."
::= { entPhysicalEntry 4 }

SYNTAX PhysicalClass
MAX-ACCESS read-only

DESCRIPTION
"An indication of the general hardware type of the physical

An agent should set this object to the standard enumeration
value which most accurately indicates the general class of
the physical entity, or the primary class if there is more
than one.
If no appropriate standard registration identifier exists
for this physical entity, then the value 'other(1)' is
returned. If the value is unknown by this agent, then the
value 'unknown(2)' is returned."
::= { entPhysicalEntry 5 }
entPhysicalParentRelPos OBJECT-TYPE
SYNTAX INTEGER (-1..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An indication of the relative position of this 'child'
component among all its 'sibling' components. Sibling
components are defined as entPhysicalEntries which 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).
This value should match any external labeling of the
physical component if possible. 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 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 a
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."
::= { entPhysicalEntry 6 }
entPhysicalName OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The textual name of the physical entity. The value of this
object should be the name of the component as assigned by
the local device and should be suitable for use in commands
entered at the device's `console'. This might be a text
name, such as `console' or a simple component number (e.g.,
port or module number), such as `1', depending on the
physical component naming syntax of the device.
If there is no local name, or this object is otherwise not
applicable, then this object contains a zero-length string.
Note that the value of entPhysicalName for two physical
entities will be the same in the event that the console
interface does not distinguish between them, e.g., slot-1
and the card in slot-1."

entPhysicalHardwareRev OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-only

DESCRIPTION
"The vendor-specific hardware revision string for the

revision identifier actually printed on the component itself
(if present).
Note that if revision information is stored internally in a
non-printable (e.g., binary) format, then the agent must
convert such information to a printable format, in an
implementation-specific manner.
If no specific hardware revision string is associated with
the physical component, or this information is unknown to
the agent, then this object will contain a zero-length
string."

entPhysicalFirmwareRev OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-only

DESCRIPTION
"The vendor-specific firmware revision string for the

Note that if revision information is stored internally in a
non-printable (e.g., binary) format, then the agent must
convert such information to a printable format, in an
implementation-specific manner.
If no specific firmware programs are associated with the
physical component, or this information is unknown to the
agent, then this object will contain a zero-length string."
::= { entPhysicalEntry 9 }
entPhysicalSoftwareRev OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-only

DESCRIPTION
"The vendor-specific software revision string for the
physical entity.
Note that if revision information is stored internally in a
non-printable (e.g., binary) format, then the agent must
convert such information to a printable format, in an
implementation-specific manner.
If no specific software programs are associated with the
physical component, or this information is unknown to the
agent, then this object will contain a zero-length string."
::= { entPhysicalEntry 10 }
entPhysicalSerialNum OBJECT-TYPE
SYNTAX SnmpAdminString (SIZE (0..32))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The vendor-specific serial number string for the physical
entity. The preferred value is the serial number string
actually printed on the component itself (if present).
On the first instantiation of an physical entity, the value
of entPhysicalSerialNum associated with that entity is set
to the correct vendor-assigned serial number, if this
information is available to the agent. If a serial number
is unknown or non-existent, the entPhysicalSerialNum will be
set to a zero-length string instead.
Note that implementations which can correctly identify the
serial numbers of all installed physical entities do not
need to provide write access to the entPhysicalSerialNum
object. Agents which cannot provide non-volatile storage for
the entPhysicalSerialNum strings are not required to
implement write access for this object.
Not every physical component will have a serial number, or
even need one. Physical entities for which the associated
value of the entPhysicalIsFRU object is equal to 'false(2)'
(e.g., the repeater ports within a repeater module), do not
need their own unique serial number. An agent does not have
to provide write access for such entities, and may return a
zero-length string.
If write access is implemented for an instance of
entPhysicalSerialNum, and a value is written into the
instance, the agent must retain the supplied value in the
entPhysicalSerialNum instance associated with the same
physical entity for as long as that entity remains
instantiated. This includes instantiations across all re-
initializations/reboots of the network management system,
including those which result in a change of the physical
entity's entPhysicalIndex value."
::= { entPhysicalEntry 11 }
entPhysicalMfgName OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The name of the manufacturer of this physical component.
The preferred value is the manufacturer name string actually
printed on the component itself (if present).
Note that comparisons between instances of the
entPhysicalModelName, entPhysicalFirmwareRev,
entPhysicalSoftwareRev, and the entPhysicalSerialNum
objects, are only meaningful amongst entPhysicalEntries with
the same value of entPhysicalMfgName.
If the manufacturer name string associated with the physical
component is unknown to the agent, then this object will
contain a zero-length string."
::= { entPhysicalEntry 12 }
entPhysicalModelName OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The vendor-specific model name identifier string associated
with this physical component. The preferred value is the
customer-visible part number, which may be printed on the
component itself.
If the model name string associated with the physical
component is unknown to the agent, then this object will
contain a zero-length string."
::= { entPhysicalEntry 13 }
entPhysicalAlias OBJECT-TYPE
SYNTAX SnmpAdminString (SIZE (0..32))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object is an 'alias' name for the physical entity as
specified by a network manager, and provides a non-volatile
'handle' for the physical entity.
On the first instantiation of an physical entity, the value
of entPhysicalAlias associated with that entity is set to
the zero-length string. However, agent may set the value to
a locally unique default value, instead of a zero-length
string.
If write access is implemented for an instance of
entPhysicalAlias, and a value is written into the instance,
the agent must retain the supplied value in the
entPhysicalAlias instance associated with the same physical
entity for as long as that entity remains instantiated.
This includes instantiations across all re-
initializations/reboots of the network management system,
including those which result in a change of the physical
entity's entPhysicalIndex value."
::= { entPhysicalEntry 14 }
entPhysicalAssetID OBJECT-TYPE
SYNTAX SnmpAdminString (SIZE (0..32))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object is a user-assigned asset tracking identifier
for the physical entity as specified by a network manager,
and provides non-volatile storage of this information.
On the first instantiation of an physical entity, the value
of entPhysicalAssetID associated with that entity is set to
the zero-length string.
Not every physical component will have a asset tracking
identifier, or even need one. Physical entities for which
the associated value of the entPhysicalIsFRU object is equal
to 'false(2)' (e.g., the repeater ports within a repeater
module), do not need their own unique asset tracking
identifier. An agent does not have to provide write access
for such entities, and may instead return a zero-length
string.
If write access is implemented for an instance of
entPhysicalAssetID, and a value is written into the
instance, the agent must retain the supplied value in the
entPhysicalAssetID instance associated with the same
physical entity for as long as that entity remains
instantiated. This includes instantiations across all re-
initializations/reboots of the network management system,
including those which result in a change of the physical
entity's entPhysicalIndex value.
If no asset tracking information is associated with the
physical component, then this object will contain a zero-
length string."

If an appropriate node in the SMI's naming hierarchy cannot

entLogicalCommunity OBJECT-TYPE
SYNTAX OCTET STRING (SIZE (0..255))
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION
"An SNMPv1 or SNMPv2C community-string which can be used to
access detailed management information for this logical
entity. The agent should allow read access with this
community string (to an appropriate subset of all managed
objects) and may also return a community string based on the
privileges of the request used to read this object. Note
that an agent may return a community string with read-only
privileges, even if this object is accessed with a read-
write community string. However, the agent must take care
not to return a community string which allows more
privileges than the community string used to access this
object.
A compliant SNMP agent may wish to conserve naming scopes by
representing multiple logical entities in a single 'default'
naming scope. This is possible when the logical entities
represented by the same value of entLogicalCommunity have no
object instances in common. For example, 'bridge1' and
'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.
For agents not accessible via SNMPv1 or SNMPv2C, the value
of this object is the empty string. This object may also
contain an empty string if a community string has not yet
been assigned by the agent, or no community string with
suitable access rights can be returned for a particular SNMP
request.
Note that this object is deprecated. Agents which implement
SNMPv3 access should use the entLogicalContextEngineID and
entLogicalContextName objects to identify the context
associated with each logical entity. SNMPv3 agents may
return a zero-length string for this object, or may continue
to return a community string (e.g., tri-lingual agent
support)."

STATUS current
DESCRIPTION
"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 which
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 (since the
entPhysicalContainedIn hierarchy can provide the same
information). If, on the other hand, more than one bridge
was utilizing ports on this module, then mappings between
each bridge and the ports it used would be appropriate.
Also, in the case of a single backplane repeater, a mapping
for the backplane to the single repeater entity is not
necessary."

which 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 which 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 any zero-indexed entry. 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.
Since only physical ports are modeled in this table, only
entries which 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."

DESCRIPTION
"A table which exposes the container/'containee'
relationships between physical entities. This table provides
all the information found by constructing the virtual
containment tree for a given entPhysicalTable, but in a more
direct format.
In the event a physical entity is contained by more than one
other physical entity (e.g., double-wide modules), this
table should include these additional mappings, which cannot
be represented in the entPhysicalTable virtual containment
tree."

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."
