H3C-ENTRELATION-MIB

Description: H3C MIB describing containment and connectivity relationships between physical and logical entities in the device.

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.

This H3C proprietary MIB describes containment and connectivity relationships between physical and logical entities on H3C network devices, complementing the standard ENTITY-MIB. It exposes relationship data such as stack-port pairings and combo-port pairings that the standard Entity MIB's physical containment tree cannot represent on its own. This module is a topology/inventory-relationship MIB rather than a fault or performance MIB, but it supports hardware status monitoring by letting an operator confirm which physical port of a combo-port pair is currently active or how stack ports are cross-connected, useful when diagnosing an unexpected loss of link. It explicitly depends on and supplements the standard IETF ENTITY-MIB, reusing its entity indexing scheme. Typically deployed on H3C modular switches/routers that support port stacking or combo (copper/fiber) port pairs. Engineers can download the H3C-ENTRELATION-MIB file directly to load it into their MIB browser.

No sample_objects were extracted for this module, but based on its stated purpose, an administrator would query the entity-relationship table to determine which physical port of a combo-port pair is currently forwarding traffic versus disabled, or which stack-port pair connects two stack members — helping explain an unexpected loss of connectivity when the "wrong" half of a combo port turns out to be active.
