Description: Supplements the IETF Entity MIB with additional physical component details.

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 ENTSUPPL-MIB?

ENTSUPPL-MIB is a vendor-neutral IETF draft-standard MIB module intended to supplement the standard ENTITY-MIB with additional descriptive details about physical hardware components in a managed device. Its general purpose is to expose extra inventory/asset attributes for physical entities -- such as additional identification, classification, or descriptive fields -- beyond what the base ENTITY-MIB provides. Conceptually, MIBs in this family aid hardware inventory and asset-status monitoring, helping confirm what physical modules/components are present and their descriptive attributes. It directly depends on and is meant to be used alongside the IETF ENTITY-MIB, sharing its entPhysicalIndex indexing. It would typically be deployed in the same way as ENTITY-MIB, across chassis-based network equipment from any vendor supporting extended entity inventory information. Engineers implementing or auditing this functionality typically reference the ENTSUPPL-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTSUPPL-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
  • chassis-based network equipment supporting ENTITY-MIB physical inventory

Monitoring Examples

No sample object names were provided for this MIB in the available source data, so no concrete object-level monitoring scenario can be honestly constructed. In general, a MIB of this kind would be polled alongside the standard entPhysicalTable to retrieve extended descriptive attributes for each physical component, but the specific supplemental object names are not present in this excerpt.
