Description: HH3C MIB for network management functions including network configuration and operational parameters on H3C 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 HH3C-NET-MAN-MIB?

HH3C-NET-MAN-MIB is an H3C enterprise MIB providing core network-management identification parameters for H3C devices, particularly useful in dynamic-address-assignment networks where a device's IP address may change. It exposes objects for the device's current management IP address and type, a custom build-information string, and a serial number, alongside configuration, monitoring, and notification object groupings. This MIB's main monitoring value is confirming device identity and reachability information (current management IP, serial number, firmware/build info) so that a network management system can reliably correlate a device across IP address changes and detect when a device has been re-provisioned or replaced. It is a foundational identification MIB that likely complements standard SNMPv2-MIB system group objects (sysDescr, sysName) rather than duplicating them. Typical deployment is across H3C's router and switch portfolio, especially in DHCP-based or dynamically addressed access networks, where administrators can download the HH3C-NET-MAN-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-NET-MAN-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 router
H3C switch in dynamic-addressing network

Monitoring Examples

A network management system can poll hh3cNMIpAddress and hh3cNMIpAddressType to track a device's current management address as it changes under dynamic addressing, correlating it against hh3cNMSerialNum to confirm device identity persists across IP reassignment. hh3cNMCustomBuildInfo lets an operator audit which firmware/build is installed fleet-wide. The hh3cNMNotify/hh3cNMNotifyObjects group can be used to trigger a notification when a device's management IP address changes unexpectedly, flagging a potential re-IP or address-conflict event.

What Can Be Monitored

OID symbolic	OID numeric	Type	Access	Description
hh3cNetMan	1.3.6.1.4.1.25506.2.90			This MIB file is to provide the object definition of the network management parameters. These parameters are used to identify devices. It is useful for devices management in a dynamic address assignment network.
hh3cNMConfigObjects	1.3.6.1.4.1.25506.2.90.1
hh3cNMMonitorObjects	1.3.6.1.4.1.25506.2.90.2

IPt hh3cNMIpAddressType	1.3.6.1.4.1.25506.2.90.3.1.1	InetAddressType	accessible-for-notify	The IP address type of specified interface on the device.
IP hh3cNMIpAddress	1.3.6.1.4.1.25506.2.90.3.1.2	InetAddress	accessible-for-notify	The IP address of specified interface on the device.
OCT hh3cNMCustomBuildInfo	1.3.6.1.4.1.25506.2.90.3.1.3	OCTET STRING	read-only	The customer-required information of devices, for example, OUI (Organizational Unique Identifier).
OCT hh3cNMSerialNum	1.3.6.1.4.1.25506.2.90.3.1.4	OCTET STRING	accessible-for-notify	The serial number used by NMS (Network Management Station) for mapping IP address and device.

hh3cNMNotifyObjectsPrefix	1.3.6.1.4.1.25506.2.90.3.2.0
NTF hh3cIpAddrChangeNotify	1.3.6.1.4.1.25506.2.90.3.2.0.1			This notification will be generated when the IP address of active management interface is changed. The change maybe originate from NMS, DHCP server or administrator. The management interfaces are the interfaces that assigned by administrator, which can be used to manage device, but may be inactive for link fault or IP address (IPv4 or IPv6) missing. The active management interface means an active interface, the IP address of which can be used for network management. This notification announces useful management IP address change. So it is triggered by significative IP address change. Suppose that two management interfaces on a device, Interface-A and Interface-B. Initially both interfaces are down and assigned no IP address. Configure Interface-A as the primary monitored interface, Interface-B as the secondary. Significative IP address change in following cases: 1. If Interface-A is assigned an IP address primarily, and it is linking up, then Interface-B will be ignored. A notification will be triggered, appending IP address of Interface-A. 2. If Interface-B is assigned an IP address primarily, and it is linking up, then Interface-A will be ignored. A notification will be triggered, appending IP address of Interface-B. 3. If IP address of that interface, which had its IP address announced to NMS, is changed since last notification triggered, then another notification will be sent to NMS. 4. Suppore that Interface-A was linked up and assigned an IP address primarily. If for some unknown reason, Interface-A is down or loses IP address, and Interface-B is assigned an IP address which is different with that announced to NMS before, then a notification will be triggered, appending the new IP address that Interface-B assigned. 5. A notification appending new IP address that Interface-A assigned will be triggered, if 4 occurs to Interface-B.
