Description: Huawei NAT extensions MIB providing Huawei-specific NAT address pool, port block, and session management objects.

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 HUAWEI-NAT-EXT-MIB?

HUAWEI-NAT-EXT-MIB is a Huawei Technologies Co., Ltd. proprietary MIB (S9300 platform, referencing RFC 4004) reporting NAT address/port bindings. Its objects cover a packet-discard counter, an address-binding table (query VRF/address, bind type, mapped VRF/address, bind ID, session count, idle time, in/out translate counters), and an address-port-binding table (query VRF/address/protocol/port, bind type, mapped VRF/address/port). As a status/performance MIB it lets an administrator confirm active NAT translations and session counts on a Huawei S9300 NAT gateway. It is deployed on Huawei Technologies S9300 platform equipment (NAT). Engineers can download the HUAWEI-NAT-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-NAT-EXT-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

  • Huawei Technologies S9300 platform equipment (NAT)

Monitoring Examples

An administrator checks hwNatAddrBindSessionCount and hwNatAddrBindCurrentIdleTime to confirm an active NAT translation's session load and idle time on a Huawei S9300 NAT gateway.

What Can Be Monitored

  • NAT address/port binding sessions and translation counters

How to Use in IPNetwork Monitor

Example using hwNatAddrBindInTranslate OID:

Select a Huawei S9300 platform equipment (NAT address/port bindings) 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 hwNatAddrBindInTranslate 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. The number of inbound packets that were translated as per this BIND entry. 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.
