Description: Manages Network Address Translation (NAT) address pools, sessions, and PAT mappings on H3C gateway 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-NAT-MIB?

HH3C-NAT-MIB is an H3C enterprise MIB for managing Network Address Translation (NAT) on H3C gateway and firewall devices, covering address pool definitions, active translation sessions, and Port Address Translation (PAT) mappings. Although the underlying source objects were not enumerated in this batch, NAT MIBs of this kind typically expose configuration data (pool ranges, translation rule bindings) as well as operational/session-state data such as current session counts and pool utilization. This MIB is used primarily to monitor the software/operational health of the NAT subsystem, for example whether an address pool is nearing exhaustion or whether session tables are approaching capacity, which are common causes of new-connection failures on a gateway. NAT functionality is closely tied to the device's IP addressing and interface MIBs since translations bind to specific interfaces and IP address types. Typical deployment is on H3C routers, security gateways, or firewalls performing address translation for internal networks accessing the internet. Engineers can download the HH3C-NAT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-NAT-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/security gateway performing NAT

Monitoring Examples

An operator would typically poll a NAT address-pool table for current allocation counts against pool size, and a NAT session table for hh3c-prefixed objects tracking active translated sessions and PAT port mappings, to detect when a pool is close to full. A sudden spike in active session count with no corresponding pool capacity increase would indicate address exhaustion likely to cause failed outbound connections for end users. Since no explicit sample object names were provided for this MIB, exact table names should be confirmed against the MIB source before building alert rules.

What Can Be Monitored

NAT pool utilization
active translation session count
PAT port mapping usage
per-interface NAT binding

How to Use in IPNetwork Monitor

Example using hh3cNATStatActiveTblCount OID:

Select an H3C router or security gateway as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hh3cNATStatActiveTblCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the active PAT session count In software. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
