Description: H3C MIB providing object information and metadata for managed entities in H3C network devices.

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 H3C-OBJECT-INFO-MIB?

H3C-OBJECT-INFO-MIB is a private H3C (Hangzhou Huawei-3Com, now H3C Technologies) MIB whose purpose is to let a network management system query whether a given managed device/agent supports a particular MIB object or feature before attempting to act on it. It exposes a single top-level object-information node used as a capability-discovery mechanism rather than a set of hardware or performance counters. Because it is a meta/support-discovery MIB, it has no direct role in monitoring hardware temperature, CPU, memory, or fault status; instead it indirectly aids software status checking by letting an NMS confirm feature/object support before polling, avoiding failed requests against unsupported objects. Its function is explicitly to sit beneath other H3C MIBs, making it a dependency-discovery helper rather than an independent monitoring module. It is deployed across H3C network devices (switches/routers) wherever an NMS needs to pre-check object support prior to full MIB polling. Network engineers evaluating or troubleshooting this functionality can download the H3C-OBJECT-INFO-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-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.

Supported Devices

H3C switch/router (vendor-specific, capability-discovery use)

Monitoring Examples

This MIB centers on the single h3cObjectInformation object, used by network management software to query object/feature support rather than to expose ongoing runtime metrics; there is no concrete anomaly-monitoring scenario to describe beyond an NMS checking h3cObjectInformation to decide whether to proceed with polling a given H3C-specific object on the device.

OIDs

OID symbolic	OID numeric	Type	Access	Description
h3cObjectInfo	1.3.6.1.4.1.2011.10.2.55			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.
h3cObjectInformation	1.3.6.1.4.1.2011.10.2.55.1
h3cObjectInfoTable	1.3.6.1.4.1.2011.10.2.55.1.1		not-accessible	MIB objects information query table.
h3cObjectInfoEntry	1.3.6.1.4.1.2011.10.2.55.1.1.1		not-accessible	The entry of h3cObjectInfoTable.
OID h3cObjectInfoOID	1.3.6.1.4.1.2011.10.2.55.1.1.1.1	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 h3cObjectInfoValue will be failed.
INT h3cObjectInfoType	1.3.6.1.4.1.2011.10.2.55.1.1.1.2	INTEGER	not-accessible	The object's properties type to be queried. The queried result will be returned by h3cObjectInfoValue. The format of the result will be different according to different h3cObjectInfoType.
OCT h3cObjectInfoTypeExtension	1.3.6.1.4.1.2011.10.2.55.1.1.1.3	OCTET STRING	not-accessible	The object's property type extension to be queried. This object's value is relative to the value of h3cObjectInfoType.
OCT h3cObjectInfoValue	1.3.6.1.4.1.2011.10.2.55.1.1.1.4	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 h3cObjectInfoType 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 h3cObjectInfoType 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 h3cObjectInfoType 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 h3cObjectInfoValue 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 h3cObjectInfoType 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[]'.
