            "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.";

                  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

                  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

                  Logical entities 'bridge1' and 'repeater1' would be

version of this MIB module is part of RFC 4133; see
the RFC itself for full legal notices.

Typedefs

Typedef Base type Abstract
PhysicalClass enumeration 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 enumerat...
PhysicalIndex int32 An arbitrary value that uniquely identifies the physical entity. The value should be a small, positive integer. Index values for different physical entities are not necessarily contiguous.
PhysicalIndexOrZero int32 This textual convention is an extension of the PhysicalIndex convention, which defines a greater than zero value used to identify a physical entity. This extension permits the additional value of zero. The semantics of the value zero are object-specific...
SnmpEngineIdOrNone binary A specially formatted SnmpEngineID string for use with the Entity MIB. If an instance of an object of SYNTAX SnmpEngineIdOrNone has a non-zero length, then the object encoding and semantics are defined by the SnmpEngineID textual convention (see STD 62, ...

Objects

Type Key

Object Type Abstract
entityGeneral container entLastChangeTime
   entLastChangeTime leaf The value of sysUpTime at the time a conceptual row is created, modified, or deleted in any of these tables: - entPhysicalTable - entLogicalTable - entLPMappingTable - entAliasMappingTable - entPhysicalContainsTable
entityLogical container entLogicalEntry
   entLogicalEntry list Information about a particular logical entity. Entities may be managed by this agent or other SNMP agents (possibly) in the same chassis.
      entLogicalCommunity leaf 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 retur...
      entLogicalContextEngineID leaf The authoritative contextEngineID that can be used to send an SNMP message concerning information held by this logical entity, to the address specified by the associated 'entLogicalTAddress/entLogicalTDomain' pair. This object, together with the associat...
      entLogicalContextName leaf The contextName that can be used to send an SNMP message concerning information held by this logical entity, to the address specified by the associated 'entLogicalTAddress/entLogicalTDomain' pair. This object, together with the associated entLogicalConte...
      entLogicalDescr leaf A textual description of the logical entity. This object should contain a string that identifies the manufacturer's name for the logical entity, and should be set to a distinct value for each version of the logical entity.
      entLogicalIndex leaf The value of this object uniquely identifies the logical entity. The value should be a small positive integer; index values for different logical entities are not necessarily contiguous.
      entLogicalTAddress leaf 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 contain the IP-addres...
      entLogicalTDomain leaf 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 Transport Mappings for Simple Network Management Protocol' (STD 62, RFC 3417 [RFC3417]).
      entLogicalType leaf 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 exam...
entityMapping container entLPMappingEntry entAliasMappingEntry entPhysicalContainsEntry
   entAliasMappingEntry list Information about a particular physical equipment, logical entity to external identifier binding. Each logical entity/physical component pair may be associated with one alias mapping. The logical entity index may also be used as a 'wildcard' (refer t...
      entAliasLogicalIndexOrZero leaf 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...
      entAliasMappingIdentifier leaf 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. ...
      entPhysicalIndex leaf Automagically generated leafref leaf.
   entLPMappingEntry list Information about a particular logical entity to physical equipment association. Note that the nature of the association is not specifically identified in this entry. It is expected that sufficient information exists in the MIBs used to manage a particul...
      entLogicalIndex leaf Automagically generated leafref leaf.
      entLPPhysicalIndex leaf The value of this object identifies the index value of a particular entPhysicalEntry associated with the indicated entLogicalEntity.
   entPhysicalContainsEntry list A single container/'containee' relationship.
      entPhysicalChildIndex leaf The value of entPhysicalIndex for the contained physical entity.
      entPhysicalIndex leaf Automagically generated leafref leaf.
entityPhysical container entPhysicalEntry
   entPhysicalEntry list Information about a particular physical entity. Each entry provides objects (entPhysicalDescr, entPhysicalVendorType, and entPhysicalClass) to help an NMS identify and characterize the entry, and objects (entPhysicalContainedIn and entPhysicalParentRelPo...
      entPhysicalAlias leaf 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 a physical entity, the value of entPhysicalAlias associated with tha...
      entPhysicalAssetID leaf This object is a user-assigned asset tracking identifier (as specified by a network manager) for the physical entity, and provides non-volatile storage of this information. On the first instantiation of a physical entity, the value of entPhysicalAssetID ...
      entPhysicalClass leaf An indication of the general hardware type of the physical entity. An agent should set this object to the standard enumeration value that most accurately indicates the general class of the physical entity, or the primary class if there is more than one e...
      entPhysicalContainedIn leaf 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 h...
      entPhysicalDescr leaf A textual description of physical entity. This object should contain a string that identifies the manufacturer's name for the physical entity, and should be set to a distinct value for each version or model of the physical entity.
      entPhysicalFirmwareRev leaf The vendor-specific firmware 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 implementatio...
      entPhysicalHardwareRev leaf The vendor-specific hardware revision string for the physical entity. The preferred value is the hardware revision identifier actually printed on the component itself (if present). Note that if revision information is stored internally in a non-printabl...
      entPhysicalIndex leaf The index for this entry.
      entPhysicalIsFRU leaf This object indicates whether or not this physical entity is considered a 'field replaceable unit' by the vendor. If this object contains the value 'true(1)' then this entPhysicalEntry identifies a field replaceable unit. For all entPhysicalEntries that...
      entPhysicalMfgDate leaf This object contains the date of manufacturing of the managed entity. If the manufacturing date is unknown or not supported, the object is not instantiated. The special value '0000000000000000'H may also be returned in this case.
      entPhysicalMfgName leaf 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, entPhysicalFirmwareRe...
      entPhysicalModelName leaf 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 compon...
      entPhysicalName leaf 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 (e.g., `console...
      entPhysicalParentRelPos leaf 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 objec...
      entPhysicalSerialNum leaf 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 ...
      entPhysicalSoftwareRev leaf 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 implementa...
      entPhysicalUris leaf This object contains additional identification information about the physical entity. The object contains URIs and, therefore, the syntax of this object must conform to RFC 3986, section 2. Multiple URIs may be present and are separated by white space c...
      entPhysicalVendorType leaf 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 an enterprise-specific registration identifier value indicating the sp...

Notifications

Notification Abstract
entConfigChange 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-e...
