Description: Provides diagnostic test control and result objects including loopback, ping, and line-test functions on Paradyne xDSL gear.

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 PDN-DIAGNOSTICS-MIB?

PDN-DIAGNOSTICS-MIB is a Paradyne proprietary MIB for xDSL and WAN access equipment, providing on-demand diagnostic test control and results, including loopback tests, bit-error-rate tests (BERT), and interface line testing. It exposes objects to configure and initiate diagnostic tests on an interface plus the resulting counters, such as packets sent/received, error counts, and elapsed test time. Its monitoring value is oriented toward hardware/line-health diagnostics: running a loopback or BERT test reveals whether a specific interface's physical line is experiencing packet loss or errors, helping isolate a hardware or cabling fault versus a configuration issue. It builds on standard interface (ifTable-style) indexing conventions, tying its test tables to the standard IF-MIB ifIndex, though it is otherwise a self-contained vendor diagnostics MIB. It is deployed on Paradyne xDSL modems/routers where field technicians or NOC staff run remote diagnostic tests to troubleshoot a suspect line. Engineers can download the PDN-DIAGNOSTICS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PDN-DIAGNOSTICS-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

Monitoring Examples

A technician would configure ifLoopbackTestTable/ifLoopbackTestEntry with loopbackTestInputNumCycles to run a loopback test, then read loopbackTestResultsPktsSent, loopbackTestResultsPktsRcvdOK, and loopbackTestResultsPktsRcvdErr to see the pass/fail outcome. A high loopbackTestResultsPktErrorRate or loopbackTestResultsPktsNotRcvd count indicates a degraded physical line, while loopbackTestResultsErrSecs and loopbackTestResultsSvrErrSecs quantify how many seconds of the test were affected by errors. The ifBERTObjectsTable would similarly be used to run a bit-error-rate test and confirm line quality before escalating a suspected hardware fault.

What Can Be Monitored

loopback test results (sent/received/error packets)
packet error rate
errored seconds during test
