Description: H3C MIB extending Power over Ethernet (PoE) management with H3C-specific port power statistics and configuration.

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-POWER-ETH-EXT-MIB?

H3C-POWER-ETH-EXT-MIB is an H3C proprietary extension to the standard Power over Ethernet MIB, adding H3C-specific per-port power statistics and configuration beyond what POWER-ETHERNET-MIB defines. Because no module description or sample objects were available for this MIB, the specific object set cannot be enumerated with certainty, but by convention such extension MIBs typically expose per-port power draw, power budget/threshold configuration, and PoE port enable/priority settings. In a monitoring context this class of MIB is generally used to track hardware power-delivery health on switch ports — actual power consumed versus the port or system power budget, and whether a port has exceeded its allocated power or entered a fault/overload state. It depends on and extends the IETF POWER-ETHERNET-MIB (RFC 3621), inheriting its base PoE port table structure. It is deployed on H3C access switches that supply inline power to devices such as IP phones, wireless access points, and PoE-powered cameras. Engineers can download the H3C-POWER-ETH-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-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 PoE-capable Ethernet switches

Monitoring Examples

No sample objects were provided for this module, so a concrete object-level polling scenario cannot be constructed without inventing names; in practice, however, an administrator would typically extend the standard pethPsePortTable with H3C-specific power-draw counters to detect a port nearing its power budget or a PSE reporting an overload condition. This MIB should be treated as a PoE power-monitoring extension pending direct inspection of its object tree for exact table and column names.

What Can Be Monitored

  • per-port PoE power consumption
  • PoE power budget utilization
  • PoE port power state/faults
