Description: IANA MIB defining textual conventions for Medium Attachment Unit (MAU) types used in IEEE 802 interface management.

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 IANA-MAU-TC-MIB?

IANA-MAU-TC-MIB is the standard IANA-maintained MIB defining dot3MauType OBJECT-IDENTITIES and the IANAifMauListBits/JackType textual conventions used by the standard MAU-MIB to enumerate Ethernet Medium Attachment Unit types and jack types. It carries no data objects of its own — new MAU type assignments require an IETF Standards Action, ensuring every value is documented in an RFC. As a structural/registry MIB it lets vendors and management tools resolve a device's reported MAU type (e.g., 100BASE-TX, 1000BASE-T) to a standardized, IANA-registered identifier. It underlies any SNMP agent implementing the standard MAU-MIB. Engineers implementing or auditing this functionality typically reference the IANA-MAU-TC-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in IANA-MAU-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.

SNMP agents implementing the standard MAU-MIB

Monitoring Examples

A MIB browser resolves a device's ifMauType value against IANA-MAU-TC-MIB's registry to display a human-readable Ethernet medium type like 100BASE-TX.

OIDs

OID symbolic	OID numeric	Description
dot3MauType	1.3.6.1.2.1.26.4
dot3MauTypeAUI	1.3.6.1.2.1.26.4.1	no internal MAU, view from AUI
dot3MauType10Base5	1.3.6.1.2.1.26.4.2	thick coax MAU
dot3MauTypeFoirl	1.3.6.1.2.1.26.4.3	FOIRL MAU
dot3MauType10Base2	1.3.6.1.2.1.26.4.4	thin coax MAU
dot3MauType10BaseT	1.3.6.1.2.1.26.4.5	UTP MAU. Note that it is strongly recommended that agents return either dot3MauType10BaseTHD or dot3MauType10BaseTFD if the duplex mode is known. However, management applications should be prepared to receive this MAU type value from older agent implementations.
dot3MauType10BaseFP	1.3.6.1.2.1.26.4.6	passive fiber MAU
dot3MauType10BaseFB	1.3.6.1.2.1.26.4.7	sync fiber MAU
dot3MauType10BaseFL	1.3.6.1.2.1.26.4.8	async fiber MAU. Note that it is strongly recommended that agents return either dot3MauType10BaseFLHD or dot3MauType10BaseFLFD if the duplex mode is known. However, management applications should be prepared to receive this MAU type value from older agent implementations.

ianaMauTC	1.3.6.1.2.1.26.7	This MIB module defines dot3MauType OBJECT-IDENTITIES and IANAifMauListBits and JackType Textual Conventions, specifying enumerated values of the ifMauTypeListBits and ifJackType objects respectively, defined in the MAU-MIB. A Standards Action (as defined in RFC 2434) is REQUIRED for the addition of the new MAU types, so that any prospective assignments are documented in an RFC. Any document that proposes such an addition is REQUIRED to note any special properties of the MAU types that it defines -- for example, side effects on the ifStackTable such as are noted in RFC 3636 Section 3.4.1 for 10GBASE-W MAUs.
