Description: H3C MIB for general network management including interface monitoring, SNMP configuration, and device management.

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-NET-MAN-MIB?

H3C-NET-MAN-MIB is H3C's general network management MIB, providing device identification and management objects intended to support dynamic address assignment environments, per its stated purpose. It exposes device IP addressing (h3cNMIpAddressType/h3cNMIpAddress), a custom build-information string, and serial number identification (h3cNMSerialNum), alongside separate configuration, monitoring, and notification object groups (h3cNMConfigObjects, h3cNMMonitorObjects, h3cNMNotify/h3cNMNotifyObjects). Its monitoring role centers on device identity and change tracking in dynamic-IP networks, confirming which physical device, by serial number and build info, currently holds a given management IP address, plus a defined notification framework for management-relevant events. It appears designed to interoperate with standard SNMP notification (SNMPv2-MIB/NOTIFICATION-TYPE) conventions given its Notify object structure. It is deployed across the H3C router and switch product line, particularly in environments using dynamic address assignment such as DHCP-managed device management IPs, and administrators can download the H3C-NET-MAN-MIB file to load it into their MIB browser for device-identity monitoring.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-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/switch (general network management)

Monitoring Examples

An admin polls h3cNMIpAddress and h3cNMIpAddressType to determine the current management address type/value of a device, then cross-references h3cNMSerialNum and h3cNMCustomBuildInfo to positively identify which physical unit that address currently belongs to, important when devices get new IPs via DHCP. The h3cNMNotify/h3cNMNotifyObjects group defines the notification objects sent when management-relevant events occur, letting a monitoring station subscribe to device-identity or configuration-change traps rather than only polling.

OID symbolic	OID numeric	Type	Access	Description
h3cNetMan	1.3.6.1.4.1.2011.10.2.90			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.
h3cNMConfigObjects	1.3.6.1.4.1.2011.10.2.90.1
h3cNMMonitorObjects	1.3.6.1.4.1.2011.10.2.90.2

IPt h3cNMIpAddressType	1.3.6.1.4.1.2011.10.2.90.3.1.1	InetAddressType	accessible-for-notify	The IP address type of specified interface on the device.
IP h3cNMIpAddress	1.3.6.1.4.1.2011.10.2.90.3.1.2	InetAddress	accessible-for-notify	The IP address of specified interface on the device.
OCT h3cNMCustomBuildInfo	1.3.6.1.4.1.2011.10.2.90.3.1.3	OCTET STRING	read-only	The customer-required information of devices, for example, OUI (Organizational Unique Identifier).
OCT h3cNMSerialNum	1.3.6.1.4.1.2011.10.2.90.3.1.4	OCTET STRING	accessible-for-notify	The serial number used by NMS (Network Management Station) for mapping IP address and device.
h3cNMNotifyObjects	1.3.6.1.4.1.2011.10.2.90.3.2
h3cNMNotifyObjectsPrefix	1.3.6.1.4.1.2011.10.2.90.3.2.0
NTF h3cIpAddrChangeNotify	1.3.6.1.4.1.2011.10.2.90.3.2.0.1			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.
