What Is C-PRODUCT-CTX-MIB?

C-PRODUCT-CTX-MIB is a vendor-specific MIB whose source file carries no ORGANIZATION or CONTACT-INFO clause identifying the manufacturer, but whose abstract states it manages the AB9300 CTX interface card, modeling ATM cross-connect buffer, traffic-shaper, and card-level configuration alongside per-VC ATM cell statistics. It defines ctxCardBufferTable (per-slot, per-queue buffer cell allocation and congestion-on/off thresholds across 16 queue buffers), ctxCardShapersTable (per-slot traffic shaper rate in cells/second across up to 7 shapers), a card-level reset object, and ctxATMStatsTable (indexed by vcpSideId, tracking received/transmitted ATM cell counts and a reset-time/date per VC connection). This data is useful for monitoring per-queue buffer congestion and per-VC cell throughput on the CTX card, and for confirming when ATM statistics were last cleared. It depends on cardSlot and vcpSideId indexing objects imported from the C-PRODUCT-BASE-MIB, indicating it is part of a larger C-PRODUCT family of enterprise MIBs for a modular ATM switching chassis. Because the input's listed vendor could not be confirmed against the MIB itself, administrators should consult the C-PRODUCT-CTX-MIB MIB text directly rather than rely on an assumed vendor's documentation.

IPNetwork Monitor allows you to monitor SNMP objects defined in C-PRODUCT-CTX-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

AB9300 CTX ATM interface card (manufacturer not identified in the MIB source)

Monitoring Examples

An operator polls ctxCardBufferCells and ctxCardCongOn/ctxCardCongOff for a given queue on the CTX card to check whether configured congestion thresholds match expected buffering behavior, then reviews ctxATMStatsRxCells/TxCells for a specific vcpSideId; a VC showing zero incrementing cell counts despite an expected active connection would point to a cross-connect or provisioning problem on that CTX card slot.

What Can Be Monitored

per-queue buffer cell allocation
congestion on/off thresholds per queue
traffic shaper rate per shaper index
per-VC transmitted/received ATM cell counts
VC statistics reset time/date
card reset action
