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 NNC-ATM-CONGESTIONSTATISTICS-MIB?
NNC-ATM-CONGESTIONSTATISTICS-MIB is a Newbridge Networks vendor-specific MIB that monitors congestion behavior at ATM switching points on Newbridge's 36170 ATM switch platform, tracking cell-level congestion across raw, short-interval, and long-interval statistics tables. Its nncAtmCongPointInfoTable identifies each congestion point and its nncAtmCongPointHardwareType (card/queue/QOS/fabric configuration), while nncAtmCongStatsRawTable exposes cumulative counters — nncAtmCongStatsTotalCellsArrived, nncAtmCongStatsTotalCellsDiscarded, nncAtmCongStatsClp0CellsDiscarded — plus per-severity accumulated time in nncAtmCongStatsLowCongestedSeconds/MediumCongestedSeconds/SevereCongestedSeconds and a live nncAtmCongStatsCurrentCongestionState and nncAtmCongStatsAlarmStatus. Parallel current/historical short- and long-interval tables (nncAtmCongStatsCurrentShortIntvlTable, nncAtmCongStatsShortIntvlTable, and their long-interval counterparts) let operators trend congestion over time rather than just view cumulative totals. It depends on ENTITY-MIB for PhysicalIndex correlation and NNC-INTERVAL-STATISTICS-TC-MIB for interval-state typing, and is deployed on Newbridge 36170 ATM switches in service-provider ATM backbones, where engineers consult the NNC-ATM-CONGESTIONSTATISTICS-MIB OID tree when investigating cell loss.
IPNetwork Monitor allows you to monitor SNMP objects defined in NNC-ATM-CONGESTIONSTATISTICS-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 36170 ATM switch (SHub Diablo/NSX/Eagle hardware)
Monitoring Examples
An operator polls nncAtmCongStatsCurrentCongestionState and nncAtmCongStatsAlarmStatus for a congestion point to see if it is currently congested, then checks nncAtmCongStatsClp0CellsDiscarded against nncAtmCongStatsTotalCellsArrived to quantify cell loss under load; rising nncAtmCongStatsSevereCongestedSeconds across successive short-interval samples would indicate a persistent, worsening congestion condition at that switching point.
What Can Be Monitored
- congestion point hardware type/QoS mapping
- cumulative cells arrived/discarded counters
- CLP0 cell discard counter
- low/medium/severe congested-seconds accumulators
- current congestion state and alarm status
- short- and long-interval congestion trend tables

How to Use in IPNetwork Monitor
Example using nncAtmCongStatsLowCongestedSeconds OID:
Select a Newbridge Networks 36170 ATM switch (SHub Diablo/NSX/Eagle hardware) 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 nncAtmCongStatsLowCongestedSeconds 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. It reports the number of seconds the congestion point was in the Low Congestion State. 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.

| nncAtmCongestionStatistics | 1.3.6.1.4.1.123.3.63 | This module contains the definitions for congestion statistics on ATM products. Congestion statistics allow the user to monitor the performance of a particular congestion point in order to alleviate future congestion problems. This MIB module contains the following tables: ATM Congestion Point Information Table ATM Raw Congestion Statistics Table. ATM Current Short Interval Congestion Statistics Table. ATM Short Interval Congestion Statistics Table. ATM Current Long Interval Congestion Statistics Table. ATM Long Interval Congestion Statistics Table. The following tables describe the mapping between a congestion point and the qualities of service available on the 36170. Each card configuration is assigned a hardware type, which is then used to determine which qualities of service are available for that particular card configuration. Release 4.0 of the 36170 supports only OC12-1 hardware. Table 1 associates a number with each hardware type. The hardware type is a function of: - type of card, - queue and QOS configuration based on ASIC used on the card, - fabric type, - switch profile, - congestion point. The Congestion Point Index is to be used as nncAtmCongPointInfoIndex, nncAtmCongPointRawIndex, nncAtmCongPointCurrentShortIntvlIndex, nncAtmCongPointShortIntvlIndex, nncAtmCongPointCurrentLongIntvlIndex, and nncAtmCongPointLongIntvlIndex. Table 2 consists of columns for each hardware type indicating which qualities of service are available for the particular hardware type. The Index column associates a number for each quality of service, which is used as the nncAtmCongStatsQOSRawIndex, nncAtmCongStatsQOSCurrentShortIntvlIndex, nncAtmCongStatsQOSShortIntvlIndex, nncAtmCongStatsQOSCurrentLongIntvlIndex, and nncAtmCongStatsQOSLongIntvlIndex. ________________________________________________________ | | SHub Diablo | SHub NSX | SHub Eagle |
