Description: Provides network management objects for H3C/3Com devices, covering system identification, NMS access configuration, and management interface settings.

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 A3COM-HUAWEI-NET-MAN-MIB?

A3COM-HUAWEI-NET-MAN-MIB is a Hangzhou H3C Technologies proprietary MIB providing basic network-management identification objects for dynamic-address-assignment networks. Its objects cover an IP-address type/value used to identify the device, a custom build-info string, a serial number, and an IP-address-change notification. As a status MIB it lets an NMS confirm a device's identity even after its management IP address changes via DHCP on an H3C network. It is deployed on H3C (3Com/Huawei) networking equipment. Engineers can download the A3COM-HUAWEI-NET-MAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-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 (3Com/Huawei) networking equipment

Monitoring Examples

An NMS receives h3cIpAddrChangeNotify and reads h3cNMSerialNum to re-identify an H3C device after its DHCP-assigned management address changed.

What Can Be Monitored

device identity and management IP-address changes

OID symbolic	OID numeric	Type	Access	Description
h3cNetMan	1.3.6.1.4.1.43.45.1.10.2.90			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.

IPt h3cNMIpAddressType	1.3.6.1.4.1.43.45.1.10.2.90.3.1.1	InetAddressType	accessible-for-notify	The IP address type of specified interface on the device.
IP h3cNMIpAddress	1.3.6.1.4.1.43.45.1.10.2.90.3.1.2	InetAddress	accessible-for-notify	The IP address of specified interface on the device.
OCT h3cNMCustomBuildInfo	1.3.6.1.4.1.43.45.1.10.2.90.3.1.3	OCTET STRING	read-only	The customer-required information of devices, for example, OUI (Organizational Unique Identifier).
OCT h3cNMSerialNum	1.3.6.1.4.1.43.45.1.10.2.90.3.1.4	OCTET STRING	accessible-for-notify	The serial number used by NMS (Network Management Station) for mapping IP address and device.

h3cNMNotifyObjectsPrefix	1.3.6.1.4.1.43.45.1.10.2.90.3.2.0
NTF h3cIpAddrChangeNotify	1.3.6.1.4.1.43.45.1.10.2.90.3.2.0.1			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.
