Description: NETGEAR-POWER-ETHERNET-MIB module

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 NETGEAR-POWER-ETHERNET-MIB?

NETGEAR-POWER-ETHERNET-MIB is a NETGEAR vendor extension that augments the standard IETF POWER-ETHERNET-MIB, adding platform-specific Power over Ethernet (PSE) hardware details not covered by the base draft MIB, for NETGEAR's PoE-capable switch line. It exposes additional PoE-related hardware data supplementing per-port power sourcing equipment status, likely including extra power budget, port group, or power-supply detail fields specific to NETGEAR hardware. Its main monitoring value is hardware health of the PoE subsystem: confirming power budget/consumption is within capacity and that individual ports/PSE groups are supplying power correctly, which is important for detecting powered-device (camera, phone, AP) outages caused by PoE faults. It explicitly depends on and augments the IETF POWER-ETHERNET-MIB (RFC 3621/draft), so it must be read together with that base MIB's tables. It is deployed on NETGEAR managed PoE switches supporting IP cameras, VoIP phones, and wireless access points. Engineers can download the NETGEAR-POWER-ETHERNET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETGEAR-POWER-ETHERNET-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.

Monitoring Examples

No sample objects were provided for this MIB, but given it augments POWER-ETHERNET-MIB, an admin would typically cross-reference pethPsePortTable entries with this MIB's NETGEAR-specific augmentation columns to see extra power-consumption or PSE-group detail per port. A drop in reported available power budget, or a NETGEAR-specific fault code on a PSE group, would indicate a powered device (e.g., a PoE camera) is at risk of losing power due to budget exhaustion. This is a reasonable inference from the module description rather than a confirmed object list.

What Can Be Monitored

PoE power budget/consumption detail
per-port PSE status extensions
PSE group power allocation

A value of user(2) means that the port power limit is equal to the value specified by agentPethPowerLimit

A value of legacy(1) means only legacy capacitive detection scheme is used. A value of 4ptdot3afonly(2) means that IEEE 802.3af 4point detection scheme is used.
