DESCRIPTION
"An indication of the vendor-specific hardware type of the

physical entity. Note that this is different from the
definition of MIB-II's sysObjectID.
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
hardware device.
If no vendor-specific registration identifier exists for
this physical entity, or the value is unknown by this agent,
then the value { 0 0 } is returned."
::= { entPhysicalEntry 3 }
entPhysicalContainedIn OBJECT-TYPE
SYNTAX INTEGER (0..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The value of entPhysicalIndex for the physical entity which
'contains' this physical entity. A value of zero indicates
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."
::= { entPhysicalEntry 4 }
entPhysicalClass OBJECT-TYPE
SYNTAX PhysicalClass
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An indication of the general hardware type of the physical
entity.
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)
McCloghrie & Bierman Standards Track [Page 13]
RFC 2037 Entity MIB using SMIv2 October 1996
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 module
labeled as 'card #3', entPhysicalParentRelPos should have
the value '3'.
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.
McCloghrie & Bierman Standards Track [Page 14]
RFC 2037 Entity MIB using SMIv2 October 1996
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 DisplayString
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."

DESCRIPTION
"Information about a particular logical entity. Entities
may be managed by this agent or other SNMP agents (possibly)
in the same chassis."

}
entLogicalIndex OBJECT-TYPE
SYNTAX INTEGER (1..2147483647)
MAX-ACCESS not-accessible

DESCRIPTION
"The value of this object uniquely identifies the logical
entity. The value is a small positive integer; index values
for different logical entities are are not necessarily
contiguous."
::= { entLogicalEntry 1 }
entLogicalDescr OBJECT-TYPE
SYNTAX DisplayString
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A textual description of the logical entity. This object
should contain a string which identifies the manufacturer's
name for the logical entity, and should be set to a distinct
value for each version of the logical entity. "
::= { entLogicalEntry 2 }
entLogicalType OBJECT-TYPE
SYNTAX AutonomousType
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An indication of the type of logical entity. This will
typically be the OBJECT IDENTIFIER name of the node in the
SMI's naming hierarchy which represents the major MIB
module, or the majority of the MIB modules, supported by the
logical entity. For example:
a logical entity of a regular host/router -> mib-2
a logical entity of a 802.1d bridge -> dot1dBridge
a logical entity of a 802.3 repeater -> snmpDot3RptrMgmt
If an appropriate node in the SMI's naming hierarchy cannot
be identified, the value 'mib-2' should be used."

RFC 2037 Entity MIB using SMIv2 October 1996
entLogicalCommunity OBJECT-TYPE
SYNTAX OCTET STRING (SIZE (1..255))
MAX-ACCESS read-only
STATUS current
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 choose to return a community string
based on the privileges of the request used to read this
object. Note that an agent may choose to 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 'main'
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 'main'
naming scope.
For agents not accessible via SNMPv1 or SNMPv2C, the value
of this object is the empty-string."
::= { entLogicalEntry 4 }
entLogicalTAddress OBJECT-TYPE
SYNTAX TAddress
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The transport service address by which the logical entity
receives network management traffic, formatted according to
the corresponding value of entLogicalTDomain.
For snmpUDPDomain, a TAddress is 6 octets long, the initial
4 octets containing the IP-address in network-byte order and
the last 2 containing the UDP port in network-byte order.
Consult 'Transport Mappings for Version 2 of the Simple

SYNTAX TDomain
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Indicates the kind of transport service by which the
logical entity receives network management traffic.
Possible values for this object are presently found in the

::= { entLogicalEntry 6 }
entLPMappingTable OBJECT-TYPE
SYNTAX SEQUENCE OF EntLPMappingEntry
MAX-ACCESS not-accessible
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
