Description: H3C MIB extending the standard entity MIB with additional physical component attributes and operational states.

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 H3C-ENTITY-EXT-MIB?

H3C-ENTITY-EXT-MIB is an H3C proprietary MIB that extends the standard IETF ENTITY-MIB with additional physical component attributes and operational states specific to H3C hardware. No sample objects were provided, but the module description confirms it carries general extended information about the device, meaning additional per-component hardware detail beyond what the base standard entity MIB provides. Such extension MIBs are typically used to monitor hardware status such as component operational state or additional identification/environmental attributes not covered by the base standard, supporting device-level fault and inventory monitoring. It explicitly depends on and extends the IETF standard ENTITY-MIB (RFC 6933/4133), sharing its entPhysicalIndex-based table structure. It is deployed on H3C routers and switches that expose extended entity/component information via SNMP. Engineers can download the H3C-ENTITY-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-ENTITY-EXT-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

  • H3C router
  • H3C switch

Monitoring Examples

No sample objects were supplied for this MIB, so specific object names cannot be cited. Consistent with its stated purpose of extending entity information, a real deployment would correlate its extension table, indexed by entPhysicalIndex per standard ENTITY-MIB convention, with the base ENTITY-MIB to obtain additional component status detail, but the exact objects cannot be confirmed from the available source.
