What Is HH3C-IP-ADDRESS-MIB?

HH3C-IP-ADDRESS-MIB is an H3C enterprise MIB that manages and tracks IPv4 interface address assignments, including primary and secondary addresses, on H3C network devices. It centers on configuration data and, notably, change notifications that fire when an interface's IP address is modified. As a monitoring tool it is used mainly for configuration-drift and fault detection: an unexpected address change on a router or switch interface can indicate misconfiguration, a scripting error, or unauthorized administrative action rather than a hardware fault. It builds on the standard IF-MIB interface index (ifIndex) to identify which interface changed. It is typically deployed across H3C routers and switches where administrators want SNMP trap-based alerting on IP address changes for change-control and security auditing. Network engineers evaluating or troubleshooting this functionality can download the HH3C-IP-ADDRESS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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.

Supported Devices

H3C router
H3C switch

Monitoring Examples

An admin would subscribe to the hh3cIpAddrNotify trap, which carries hh3cIpAddrNotifyIfIndex, hh3cIpAddrOldIpAddress, and hh3cIpAddrNewIpAddress to identify exactly which interface changed address and what the old and new values were. Seeing this trap fire outside of a scheduled maintenance window would reveal an unplanned address change, prompting investigation into DHCP reassignment or unauthorized configuration edits. The hh3cIpAddrNotifyObjectsPrefix and related scalar objects supply supporting prefix/mask context for the notification.

What Can Be Monitored

interface IP address changes
old vs new address values
affected interface index

OIDs

OID symbolic	OID numeric	Type	Access	Description
hh3cIpAddrMIB	1.3.6.1.4.1.25506.2.67			The MIB module for managing IPv4 address.

hh3cIpAddrSetTable	1.3.6.1.4.1.25506.2.67.1.1.1		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 hh3cIpAddrReadTable and ipAddrTable in IP-MIB. This table is used to configure IPv4 addresses of an interface identified by hh3cIpAddrSetIfIndex. When users create or delete an entry in this table, the agent also increases or reduces a corresponding entry in the hh3cIpAddrReadTable 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 hh3cIpAddrReadTable. All IPv4 addresses in this table will also show in ipAddrTable in IP-MIB.
hh3cIpAddrSetEntry	1.3.6.1.4.1.25506.2.67.1.1.1.1		not-accessible	Define the IPv4 address information.
