Description: Provides object information and metadata registry for HP/Comware SNMP management infrastructure.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is HPN-ICF-OBJECT-INFO-MIB?

HPN-ICF-OBJECT-INFO-MIB is a private infrastructure MIB in the HP/H3C Comware (ICF) enterprise MIB family, used internally by the SNMP agent to advertise which management objects and MIB modules it actually supports. Rather than exposing device performance or configuration data itself, it acts as a capability-discovery registry that a network management station (NMS) can query before invoking other MIBs, ensuring compatibility across firmware versions and platform variants. It exposes metadata about object support rather than categories like interfaces, environment, or traffic counters directly. Its monitoring role is indirect: it helps an NMS determine whether hardware/software status objects (fan, power, temperature, CPU, memory MIBs, etc.) are present on a given Comware device before polling them, avoiding failed GET requests. It depends on the broader HPN-ICF/Comware private MIB tree and is typically deployed alongside other HPN-ICF-* modules on HP/H3C Comware switches and routers as a compatibility layer for NMS software. Engineers can download the HPN-ICF-OBJECT-INFO-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-OBJECT-INFO-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

The MIB exposes a single object, hpnicfObjectInformation, which returns metadata (such as supported OIDs or capability flags) that management software queries to check whether a specific feature MIB is implemented on the connected agent. In practice, an NMS would poll hpnicfObjectInformation once at discovery time to decide whether it is safe to subsequently poll environmental or interface MIBs on that device, rather than to detect a runtime anomaly. Because it is a metadata/discovery object rather than a live counter, it does not itself surface faults or performance data.

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpnicfObjectInfo	1.3.6.1.4.1.11.2.14.11.15.2.55			This MIB is used to acquire information from the agent. Before a NMS takes some actions, it is not sure whether the agent supports it or not. This MIB is used to solve this problem.
hpnicfObjectInformation	1.3.6.1.4.1.11.2.14.11.15.2.55.1
hpnicfObjectInfoTable	1.3.6.1.4.1.11.2.14.11.15.2.55.1.1		not-accessible	MIB objects information query table.
hpnicfObjectInfoEntry	1.3.6.1.4.1.11.2.14.11.15.2.55.1.1.1		not-accessible	The entry of hpnicfObjectInfoTable.
OID hpnicfObjectInfoOID	1.3.6.1.4.1.11.2.14.11.15.2.55.1.1.1.1	OBJECT IDENTIFIER	not-accessible	The OID of the MIB object which is queried. If the user has no privilege accessing to the object referred by this OID, get operation on hpnicfObjectInfoValue will be failed.
INT hpnicfObjectInfoType	1.3.6.1.4.1.11.2.14.11.15.2.55.1.1.1.2	INTEGER	not-accessible	The object's properties type to be queried. The queried result will be returned by hpnicfObjectInfoValue. The format of the result will be different according to different hpnicfObjectInfoType.
OCT hpnicfObjectInfoTypeExtension	1.3.6.1.4.1.11.2.14.11.15.2.55.1.1.1.3	OCTET STRING	not-accessible	The object's property type extension to be queried. This object's value is relative to the value of hpnicfObjectInfoType.
OCT hpnicfObjectInfoValue	1.3.6.1.4.1.11.2.14.11.15.2.55.1.1.1.4	OCTET STRING	read-only	Return property value of the queried object. Zero length string is the default value of this object which means no value is returned. If the request is invalid, then the result should be the default value. If the value of hpnicfObjectInfoType is accessType, the rules below should be followed. 1) The returned value must have prefix 'A', and followed by some nonnegative integers. The format is like 'A2'. 2) The nonnegative integers and the meaning of them are as follow: 0 means 'not-accessible'. 1 means 'notification'. 2 means 'read-only'. 3 means 'read-write'. 4 means 'read-create'. 5 means 'write-only'. 6 means 'accessible-for-notify'. 7 means 'error'. --the above values are defined by standard protocol 101 means 'not implemented'. -- The queried node is not implemented by agent. 102 means 'unknown error'. -- Query failed for unknown reason. If the value of hpnicfObjectInfoType is dataType, the rules below should be followed. 1) The returned value must have prefix 'T', and followed by string which has format like 2), such as 'T1', the character '1' means INTEGER. 2) The following data types are defined in standard protocol, the values in brackets will be returned to indicate these data types. INTEGER(1) Integer32(2) Unsigned32(4) Gauge(6) Counter(7) Counter32(8) Counter64(9) TimeTicks(10) OCTET STRING(11) OBJECT IDENTIFIER(12) IpAddress(13) NetworkAddress(14) Opaque(15) BITS(16) If the value of hpnicfObjectInfoType is dataRange, the rules below should be followed. 1) The returned value must have prefix 'R', and followed by string which has the format like 2) to 5), such as 'R[1,1]'. 2) If hpnicfObjectInfoValue returns Integer32, the format is as followed. Suppose A is a MIB object. If SYNTAX of A is 'Integer32{1\|2\|3\|5\|6\|7}', the format is 'R[1,3],[5,7]'. If SYNTAX of A is 'Integer32{1\|3}', the format is 'R[1,1],[3,3]'. If SYNTAX of A is 'Integer32', the format is 'R[]' which means the default value range of Integer32 between -2147483648 and 2147483647. 3) The process of Counter, Counter32, Counter64, Unsigned32, Gauge32, INTEGER is the same as that of Integer32. 4) If SYNTAX of A is other types such as OCTET STRING, then this object returns default value 'R[]'. 5) If SYNTAX of A is 'BITS{a(0),b(1)}', the format is 'R[0,0],[1,1]'. If the value of hpnicfObjectInfoType is dataLength, the rules below should be followed. 1) The returned value must have prefix 'L', and followed by string which has the format like 2) to 4), such as 'L[6,6]'. 2) If SYNTAX of A is 'OCTET STRING(SIZE (6\|10..255))', the format is 'L[6,6],[10,255]'. If SYNTAX of A is 'OCTET STRING', the format is like 'L[]' which means the default length of OCTET STRING between 0 and 65535. 3) If SYNTAX of A is BITS, the format of it is the same as OCTET STIRNG. But its unit is in bit, not in byte. 4) If SYNTAX of A is other types such as INTEGER and IpAddress, this object returns 'L[]'.
