Description: Enterasys Networks proprietary MIB for configuring and monitoring NAT (Network Address Translation) on Enterasys 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 ENTERASYS-NAT-MIB?

ENTERASYS-NAT-MIB is an Enterasys Networks proprietary MIB module for configuring and monitoring Network Address Translation (NAT) functionality on Enterasys routing/switching devices. It exposes NAT resource-consumption data covering address pools, translation rules (static and list-based), port maps, and the live NAT binding table. Its primary monitoring value is tracking software resource exhaustion: current, high-water, deleted, and total binding counts, plus explicit counters for bindings that were exhausted, hit a configured maximum, or failed due to no available IP address. There is no explicit dependency on another standard MIB stated in the module, though it complements standard IP-forwarding and interface MIBs used alongside NAT. It is typically deployed on Enterasys edge routers or Layer 3 switches performing address translation between private and public address space, and network teams generally perform an ENTERASYS-NAT-MIB download from vendor documentation before adding these NAT counters to their monitoring system.

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

  • Enterasys/Extreme Networks routers and Layer 3 switches

Monitoring Examples

An admin would poll etsysNatStatsBindingsCurrent against etsysNatStatsBindingsHigh to see how close the device's NAT table is to historical peak usage, and watch etsysNatStatsBindingsExhausted and etsysNatStatsBindingsMaxReached for signs the translation table is full. A rising etsysNatStatsBindingsNoIpAddr count would reveal that clients are failing to get a translated address because the configured pool is depleted. Tracking etsysNatStatsPoolsUsed and etsysNatStatsPortMapsUsed alongside etsysNatStatsStaticRulesUsed helps confirm which resource is the bottleneck.

What Can Be Monitored

  • NAT pool utilization
  • static/list rule usage
  • current and peak NAT bindings
  • exhausted/max-reached binding events
  • port map usage
  • failed translations due to no IP address

How to Use in IPNetwork Monitor

Example using etsysNatStatsBindingsDeleted OID:

Select an Enterasys Networks router/Layer 3 switch (legacy, later Extreme Networks) (Network Address Translation) 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 etsysNatStatsBindingsDeleted into the Find box to locate it in the OID tree, then select it and click OK. This object contains the total number of NAT bindings that have been deleted. 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.
