Description: Monitors Xedia Corp. NAT translation table entries, address mapping statistics, and session counts.

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 XEDIA-NETWORK-ADDRESS-TRANSLATOR-MIB?

The XEDIA-NETWORK-ADDRESS-TRANSLATOR-MIB is Xedia Corporation's proprietary MIB for its built-in Network Address Translator (xnat), modeled on RFC 1631, which lets hosts on a private RFC1918 network share registered public IP addresses to reach the internet. It is organized under top-level objects, groups, and conformance nodes that hold the underlying translation-table and mapping-statistics objects used to track active NAT sessions. Its monitoring value centers on the NAT software function's operational status: how many translation entries or sessions are active and whether the translation address pool is nearing exhaustion. It is a Xedia-proprietary reimplementation of the concept later standardized in the IETF NAT-MIB, but is not itself dependent on that or other standard MIBs. It would be deployed on Xedia routers providing internet access for small or branch-office private networks needing address translation. Engineers can download the XEDIA-NETWORK-ADDRESS-TRANSLATOR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in XEDIA-NETWORK-ADDRESS-TRANSLATOR-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.

Monitoring Examples

The sampled object names available (xnatObjects, xnatGroups, xnatConformance, xnatCompliances) are top-level structural and conformance nodes rather than specific runtime tables, so exact translation-table object names cannot be confirmed from this extract. Per the module's stated purpose, an operator would typically watch active translation/session counts for unusually high values suggesting the address pool is close to exhaustion, or a sudden drop to zero suggesting the NAT function has failed.

What Can Be Monitored

active NAT translation session count
address mapping statistics
NAT address pool utilization

xediaNetworkAddressTranslatorMIB	1.3.6.1.4.1.838.3.23			This module defines objects for the management of Xedia's proprietary Network Address Translator. This translator is based on RFC1631 and its successors. The purpose of the Xedia Network Address Translator (xnat) is to allow hosts in private networks using the RFC1918 address space to communicate with the public Internet by translating private IP addresses to globally unique IP addresses registered with the IANA.
