Category: ATM, Network Interfaces, Textual Conventions and Registries

Description: Provides textual conventions and OBJECT-IDENTITY definitions used by MIB modules for managing ATM-based interfaces, devices, networks, and services.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring ATM-TC-MIB with a free 30-day trial of IPNetwork Monitor.

What Is ATM-TC-MIB?

ATM-TC-MIB is a textual-conventions module in the ATM (Asynchronous Transfer Mode) networking MIB family, providing shared data types and OBJECT-IDENTITY definitions rather than device-specific runtime data. It doesn't expose monitorable counters itself; instead it defines conventions like traffic descriptor types that other ATM MIBs (e.g. ATM-MIB, ATM2-MIB) reference to describe virtual circuits, cell rates, and QoS classes on ATM interfaces. Because it is purely a support module, it has no direct role in exposing hardware/software health data such as uptime or temperature; it underpins the data types used by the ATM MIBs that do report that information. As the ATM-TC-MIB MIB file, it depends heavily on SNMPv2-SMI and SNMPv2-TC and is designed to be imported by other ATM-related MIB modules. It is typically deployed alongside carrier-grade ATM switches, routers with ATM interfaces, and DSL/telco access equipment.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-TC-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

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer
  • ATM switches and routers
  • ATM-capable network interfaces

Monitoring Examples

As a TC-only module, ATM-TC-MIB does not define runtime data objects that would be polled directly for monitoring; its only sample object, atmTrafficDescriptorTypes, is an OBJECT-IDENTITY registry of traffic descriptor type identifiers used by other MIBs. Actual monitoring of ATM VCs, cell counts, or PVC status happens through MIBs like ATM-MIB that import these conventions. There is no realistic standalone monitoring scenario for this module.
