Hi,
You are probably looking for this object:
.1.3.6.1.2.1.47.1.1.1.1.3
entPhysicalVendorType OBJECT-TYPE
-- FROM ENTITY-MIB
-- TEXTUAL CONVENTION AutonomousType
SYNTAX OBJECT ID
MAX-ACCESS read-only
STATUS Current
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."
.1.3.6.1.2.1.1.2
sysObjectID OBJECT-TYPE
-- FROM SNMPv2-MIB
SYNTAX OBJECT ID
MAX-ACCESS read-only
STATUS Current
DESCRIPTION "The vendor's authoritative identification of the network
management subsystem contained in the entity. This value is
allocated within the SMI enterprises subtree (1.3.6.1.4.1)
and provides an easy and unambiguous means for determining
`what kind of box' is being managed. For example, if vendor
`Flintstones, Inc.' was assigned the subtree
1.3.6.1.4.1.4242, it could assign the identifier
1.3.6.1.4.1.4242.1.1 to its `Fred Router'."
.1.3.6.1.2.1.47.1.1.1.1.13.58
entPhysicalModelName OBJECT-TYPE
-- FROM ENTITY-MIB
-- TEXTUAL CONVENTION SnmpAdminString
SYNTAX OCTET STRING (0..255)
DISPLAY-HINT "255a"
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."
