What Is IANA-CHARSET-MIB?
IANA-CHARSET-MIB is an IETF/IANA-maintained module that defines a single textual convention, IANACharset, used to specify the character-set encoding of string objects in other MIB modules, based on the IANA Charset Registry (RFC 2978). It is a pure type-definition module with no vendor association and no device-specific data. Looking up the IANA-CHARSET-MIB OID assignment confirms this module carries no separate monitorable runtime objects of its own — no interfaces, environment, or performance counters — since its sole purpose is to standardize how character encoding is expressed elsewhere. Many other MIBs (particularly printer, fax, and internationalization-aware MIBs) depend on this TC to declare the encoding of their string-valued objects, making it a shared cross-MIB dependency. It is present conceptually across any SNMP deployment where a device's MIBs need to declare non-ASCII string encodings.
IPNetwork Monitor allows you to monitor SNMP objects defined in IANA-CHARSET-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 or device class
Monitoring Examples
This module defines only the IANACharset textual convention for use by other MIBs — it has no runtime data objects of its own, so there is no monitoring scenario to describe; its role is purely to let other MIBs tag string objects with a character-set encoding.

| ianaCharsetMIB | 1.3.6.1.2.1.106 | This MIB module defines the IANACharset TEXTUAL-CONVENTION. The IANACharset TC is used to specify the encoding of string objects defined in a MIB. Each version of this MIB will be released based on the IANA Charset Registry file (see RFC 2978) at http://www.iana.org/assignments/character-sets. Note: The IANACharset TC, originally defined in RFC 1759, was inaccurately named CodedCharSet. Note: Best practice is to define new MIB string objects with invariant UTF-8 (RFC 3629) syntax using the SnmpAdminString TC (defined in RFC 3411) in accordance with IETF Policy on Character Sets and Languages (RFC 2277).
