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 A3COM-HUAWEI-ENTRELATION-MIB?
The A3COM-HUAWEI-ENTRELATION-MIB is a vendor-specific H3C (Huawei-3Com) MIB that supplements the standard ENTITY-MIB by describing relationships between physical and logical entities in a device's hardware topology that Entity-MIB cannot express, such as stacked-port pairs and combo-port pairs. Rather than exposing performance counters, it exposes structural/configuration data describing how physical entities relate to one another within a chassis. Its main monitoring value is hardware topology awareness for management software, confirming that a stack or combo-port pairing is correctly recognized and mapped, which serves as a proxy for correct physical wiring and slot/port presence. It explicitly depends on and extends the standard IETF ENTITY-MIB, acting as a companion module rather than a standalone one. It is typically deployed on H3C/Huawei-3Com modular switches and routers that support stacking or combo (copper/fiber shared) ports, helping network management systems render accurate physical topology. Network engineers evaluating or troubleshooting this functionality can download the A3COM-HUAWEI-ENTRELATION-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-ENTRELATION-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 (Huawei-3Com) modular switch/router with stacking or combo ports
Monitoring Examples
Because no specific object names are exposed in the sampled data, an admin would poll the entity-relationship table alongside standard ENTITY-MIB entPhysicalIndex values to see which physical port index is paired with another as a stack link or combo port set. A missing or unexpected pairing entry would indicate a stack cable is unplugged or a combo port has not negotiated correctly.
What Can Be Monitored
- physical entity relationships (stack port pairs, combo port pairs)
- chassis/hardware topology mapping
- stack link presence
- combo port pairing status
