Description: Manages Spring Tide Networks network address translation pool configuration and active mapping state.

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 STN-NAT-MIB?

STN-NAT-MIB is a Spring Tide Networks, Inc. (edge-router vendor, later Lucent, built on SPRING-TIDE-NETWORKS-SMI/STN-ROUTER-MIB) proprietary MIB reporting Network Address Translation statistics. Its Layer 2 table, keyed by ifIndex, records inside/outside packet-miss and packet-hit counts, untranslated inside/outside packet counts, ALG (Application-Level Gateway) packet counts, and flow ID, while a NAT-group table records subnet interface instance, outside/inside base-end address ranges, translation mode, address idle time, address-translation-available flag, max FTP sessions (total and per inside address), and FTP control-session idle time. As a status/configuration MIB it lets an administrator confirm NAT address-pool ranges and watch translation hit/miss rates on a Spring Tide Networks (Lucent) edge router. It is deployed on Spring Tide Networks (Lucent) edge-routing platforms (NAT). Engineers can download the STN-NAT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in STN-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

Spring Tide Networks (Lucent) edge-routing platforms (NAT)

Monitoring Examples

An administrator checks stnNatGroupAddrTransAvailable and stnNatL2InsidePktMisses to confirm NAT address-pool availability and translation activity on a Spring Tide Networks (Lucent) edge router.

How to Use in IPNetwork Monitor

Example using stnNatL2InsidePktMisses OID:

Select a Spring Tide Networks (Lucent) edge router (NAT translation status) 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 stnNatL2InsidePktMisses 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 packets received from the 'inside' whose translation was unknown and needed to be learned. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
