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 PHIHONG-PoE-MIB?

PHIHONG-PoE-MIB is a Phihong enterprise MIB for managing Power-over-Ethernet (PoE) hub, injector, and switch products from this major PoE power-supply hardware vendor. It exposes system-level hardware identification -- product part number, hardware version, firmware version, description, and channel count -- alongside PoE-specific power management objects such as total power consumption, per-port power enable, and administrative actions like hub reset, restore-factory-defaults, and save-configuration. It is explicitly used to monitor hardware and firmware status, including hardware/firmware version and total power consumption, serving as both a power-delivery health monitor for detecting overload or misconfiguration of PoE ports and a device-management interface for reset/config-save actions. No dependency on other standard MIBs is evident; it appears to be a self-contained vendor MIB. It is typically deployed on Phihong PoE injector/hub/switch hardware supplying power to IP phones, wireless access points, and IP cameras in enterprise LANs. Engineers can download the PHIHONG-PoE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PHIHONG-PoE-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.

Phihong PoE hub/switch/injector

Monitoring Examples

An admin could poll poeSystemConsumptionPower to track total power draw across the unit and poeSystemNumberOfChannel alongside poeSystemAllPortPowerEnable to confirm how many ports are enabled for power delivery. Checking poeSystemHWVersion and poeSystemFirmwareVersion verifies the deployed hardware/firmware revision, and if poeSystemConsumptionPower approaches the unit's rated capacity while several PoE-powered APs go offline, that indicates the hub is overloaded and shedding ports.

What Can Be Monitored
