Description: Extends standard ATM MIB objects with Paradyne-specific virtual circuit provisioning and performance counter attributes.

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-ATMEXT-MIB?

PDN-ATMEXT-MIB is a Paradyne enterprise MIB extending the IETF standard ATM-MIB (RFC 2515) with additional per-interface objects for ATM virtual-circuit bandwidth provisioning and performance thresholds. It exposes bandwidth utilization/reservation objects across the standard ATM service categories (CBR, VBR-RT, VBR-NRT, UBR), both reserved and actually-assigned values, plus an HEC (header error control) error threshold. Its monitoring purpose is performance/capacity health of ATM interfaces -- seeing how much of each service category's bandwidth is reserved versus actually assigned/in-use, and detecting line-quality degradation via HEC error thresholds, important for capacity planning and diagnosing ATM cell-layer errors. It has an explicit stated dependency on the standard ATM-MIB (RFC 2515), whose interface/VCL tables it extends rather than duplicates. It is deployed on Paradyne ATM/DSL access equipment provisioning multiple ATM service classes over a shared uplink, making PDN-ATMEXT-MIB SNMP monitoring a routine part of ATM capacity-planning workflows.

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

Paradyne ATM/DSL access equipment

Monitoring Examples

An operator polls pdnAtmIfConfExtTable/Entry (per ATM interface) comparing pdnAtmIfConfExtBandwidthUtilVbrRtReserved against pdnAtmIfConfExtBandwidthUtilVbrRtAssigned to see how much real-time VBR bandwidth is actually in use versus provisioned, informing capacity planning. A rising count against pdnAtmIfConfExtHecErrorThreshold would flag cell-layer header errors indicating a degrading ATM physical link. Comparing the CBR, VBR-NRT, and UBR reserved/assigned pairs across interfaces helps identify over- or under-subscribed ATM uplinks.

What Can Be Monitored

ATM bandwidth reserved vs. assigned per service category (CBR/VBR-RT/VBR-NRT/UBR)
HEC error threshold
per-interface ATM utilization

How to Use in IPNetwork Monitor

Example using pdnAtmIfConfExtVbrRtBandwidthUtil OID:

Select a Paradyne ATM/DSL access equipment (VC bandwidth/HEC threshold extensions) 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 pdnAtmIfConfExtVbrRtBandwidthUtil 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 bandwidth utilization for realtime vbr type traffic expressed as a percentage. 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 utilization approaches its capacity limit, since sustained high utilization often precedes congestion or degraded performance. Click Finish to create the monitor; you can adjust any parameter later.
