Description: Manages Newbridge Networks E3 interface configuration, framing mode, and performance statistics.

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 NNCEXTE3-MIB?

NNCEXTE3-MIB is a vendor MIB from Newbridge Networks that provides extensions to standard E3 (34 Mbps digital transmission) interface objects, supplementing RFC 1407 as stated explicitly in its module description. It exposes interface configuration data (such as framing mode) and performance/error statistics for E3 transmission interfaces. Its monitoring value lies in interface performance and fault status: tracking E3 line framing errors, signal degradation, and performance counters to detect transmission-line problems on a telecom trunk, which is a hardware/physical-layer health indicator. It has an explicit and direct dependency on RFC 1407 (the standard DS3/E3 MIB), extending rather than replacing its object model. It was deployed on Newbridge Networks telecom transmission equipment carrying E3 trunks in carrier and enterprise WAN environments. Network engineers evaluating or troubleshooting this functionality can download the NNCEXTE3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NNCEXTE3-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

Newbridge Networks E3 transmission equipment

Monitoring Examples

An operator would poll the vendor E3 extension objects alongside the standard RFC 1407 dsx3ConfigTable/dsx3IntervalTable entries to get framing-mode and enhanced performance statistics for each E3 port, revealing rising error-second counts that indicate a degrading physical circuit or a framing mismatch with the far-end equipment. No vendor-specific table or object names were disclosed in the sample data.

How to Use in IPNetwork Monitor

Example using nncExtE3Current15MinESs OID:

Select a Newbridge Networks E3 transmission equipment 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 nncExtE3Current15MinESs 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 counter associated with the number of Path Errored Seconds encountered by a E3 interface in the current 15 minute interval. 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 Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
