Category: Cisco Devices, Textual Conventions and Registries
Description: Defines Cisco textual conventions that exclude unsigned 32-bit integer types for compatibility with platforms lacking U32 support.
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 CISCO-TC-NO-U32?
CISCO-TC-NO-U32 is a small textual-convention (TC) support module used across the broader family of Cisco enterprise MIBs. Its purpose is definitional rather than operational: it supplies data-type conventions for platforms or SMI toolchains that do not support the standard Unsigned32 ASN.1 type, letting other Cisco MIBs reference a common substitute type instead of each redefining one. It exposes no scalars, tables, traps, or status data of its own, so it plays no direct role in hardware or software health monitoring. Its explicit dependency is on the general Cisco MIB conventions ecosystem, since many other CISCO-*-MIB modules IMPORT its textual conventions when compiled against older or constrained SMI environments. It is typically encountered only indirectly, as a compile-time dependency pulled in by MIB compilers/parsers (such as PySMI) rather than something an operator polls or dashboards. Network engineers evaluating or troubleshooting this functionality can download the CISCO-TC-NO-U32 file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-TC-NO-U32. 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
- Cisco networking equipment (indirect, compiler-level dependency)
- vendor-neutral in role (a shared textual-convention definitions module, not a monitored entity itself)
Monitoring Examples
With an empty sample_objects list and a module description limited to defining textual conventions, CISCO-TC-NO-U32 has nothing to poll — it supplies type definitions consumed at MIB-compile time by other modules rather than runtime OIDs. There is no monitoring scenario to construct here; its 'use' is entirely in enabling correct parsing/compilation of dependent Cisco MIBs.
