Description: H3C MIB for managing IPv4 address assignments on interfaces including primary and secondary address configuration.

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-IP-ADDRESS-MIB?

H3C-IP-ADDRESS-MIB is a vendor-specific MIB from H3C (the Hewlett Packard Enterprise / Huawei-3Com networking lineage) that manages notifications for IPv4 address assignment changes on device interfaces. Rather than exposing broad configuration tables, it centers on a notification group that carries interface index and old/new address values whenever an interface's IP address is altered. Its primary monitoring value is software-status awareness: it lets administrators detect in real time when an interface's IP address configuration has changed, which can indicate misconfiguration, DHCP renumbering, or unauthorized network changes. It has a light dependency on the standard IF-MIB for interpreting the interface index referenced in its notifications. It is typically deployed on H3C/HPE Comware-based routers and switches where operations teams want proactive SNMP trap alerts for IP address change auditing and security compliance. Engineers can download the H3C-IP-ADDRESS-MIB file directly to load it into their MIB browser.

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

An admin would configure the SNMP manager to trap on h3cIpAddrNotify, which carries h3cIpAddrNotifyIfIndex, h3cIpAddrOldIpAddress, and h3cIpAddrNewIpAddress to pinpoint exactly which interface changed and what its address was before and after. A sudden flood of these traps on a normally-static interface (e.g., a WAN uplink) would indicate either an operator error, a rogue DHCP server, or a spoofing attempt. Because the MIB is notification-only, there are no polled tables to walk; monitoring is purely event-driven via trap reception.

What Can Be Monitored

IP address change events
interface index of address change
previous IP address
new IP address

OID symbolic	OID numeric	Type	Access	Description
h3cIpAddrMIB	1.3.6.1.4.1.2011.10.2.67			The MIB module for managing IPv4 address.
h3cIpAddressObjects	1.3.6.1.4.1.2011.10.2.67.1
h3cIpAddressConfig	1.3.6.1.4.1.2011.10.2.67.1.1
h3cIpAddrSetTable	1.3.6.1.4.1.2011.10.2.67.1.1.1		not-accessible	The table of address information is relevant to this entity's IPv4 addresses for setting. The address information that can be read and set in this table is a subset of the address information that can be read in h3cIpAddrReadTable and ipAddrTable in IP-MIB. This table is used to configure IPv4 addresses of an interface identified by h3cIpAddrSetIfIndex. When users create or delete an entry in this table, the agent also increases or reduces a corresponding entry in the h3cIpAddrReadTable and ipAddrTable in IP-MIB. When an interface which has been assigned IPv6 address is deleted, the agent also deletes the entry corresponding to the interface in this table and h3cIpAddrReadTable. All IPv4 addresses in this table will also show in ipAddrTable in IP-MIB.
