DESCRIPTION
"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-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 if this information is unknown to
the agent, then this object will contain a zero-length
string."

convert such information to a printable format, in an
implementation-specific manner.
If no specific firmware programs are associated with the

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 that 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 resulting in a change of the physical
entity’s entPhysicalIndex value."

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

DESCRIPTION
"The vendor-specific model name identifier string associated
with this physical component. The preferred value is 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."

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 a physical entity, the value
of entPhysicalAlias associated with that entity is set to
the zero-length string. However, the 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 resulting in a change of the physical
entity’s entPhysicalIndex value."

DESCRIPTION
"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 associated with that entity is set to
the zero-length string.
Not every physical component will have an 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

physical entity) for as long as that entity remains
instantiated. This includes instantiations across all

If no asset tracking information is associated with the

DESCRIPTION
"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 characters. Leading and trailing white space
characters are ignored.
If no additional identification information is known
about the physical entity or supported, the object is not
instantiated. A zero length octet string may also be
returned in this case."

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 that 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 if 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)."
