Description: HH3C extension MIB for Power over Ethernet (PoE) providing vendor-specific PoE port and PSE 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 HH3C-POWER-ETH-EXT-MIB?

HH3C-POWER-ETH-EXT-MIB is an H3C (Hangzhou Huawei-3Com) vendor extension MIB providing Power over Ethernet (PoE) management beyond the standard PoE MIB, covering per-port PSE (Power Sourcing Equipment) and port-level PoE configuration and status on H3C switches. It is expected to expose categories such as PoE port enable/disable state, power budget/allocation per port and per PSE, power priority settings, and detected powered-device class or fault conditions. Its core monitoring value is hardware power-delivery health: whether a port is successfully supplying power to a connected device (e.g., IP phone, AP, camera), how much power budget remains on the PSE, and whether a port has faulted due to overcurrent or overload, which is a direct hardware status indicator. As a PoE "extension" MIB it is built on top of the standard POWER-ETHERNET-MIB (RFC 3621/IEEE 802.3af/at), adding H3C-specific detail rather than replacing it. It is typically deployed on H3C/HPE Comware-based access switches in enterprise LANs delivering power to IP phones, wireless access points, and PoE cameras. Network engineers evaluating or troubleshooting this functionality can download the HH3C-POWER-ETH-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-POWER-ETH-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 Comware-based Ethernet switch
  • HPE (H3C) PoE access switch

Monitoring Examples

No sample objects were available in the source data for this MIB, so a grounded polling example naming real objects cannot be constructed here; based on the module's role as a PoE extension, a realistic use would involve polling per-port power-consumption and remaining-PSE-budget objects to detect a port nearing its power limit or a powered-device class mismatch, but the exact object names cannot be confirmed from this source.

What Can Be Monitored

  • PoE port enable state
  • power budget/allocation
  • port power priority
  • powered-device fault/overload status
