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-GREENETHERNET-PRIVATE-MIB?

This is a Netgear private MIB that manages and monitors the IEEE 802.3az Energy Efficient Ethernet (EEE) and Low Power Idle (LPI) "Green Ethernet" feature on Netgear managed switches. It exposes configuration objects for EEE mode and wake/idle timers, plus historical performance data tracking how much time each interface spent in low-power idle state and cumulative energy savings. Rather than hardware faults, its monitoring focus is software/feature status and power-related performance: agentGreenCumEnergySaving reports estimated energy saved, and the agentGreenEeeLpiHistory table tracks per-interface LPI percentage over time, letting an admin verify the power-saving feature is actually engaging on idle links. It is a vendor-private extension layered on top of the standard IF-MIB interface table, since the LPI history is indexed by interface. It is deployed on Netgear managed switches in offices or wiring closets where administrators want to verify and report on energy efficiency compliance, and administrators can download the NETGEAR-GREENETHERNET-PRIVATE-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETGEAR-GREENETHERNET-PRIVATE-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

An admin would poll agentGreenEeeMode to confirm EEE is enabled, then check agentGreenIntfEeeLpiHistoryEntry rows keyed by agentGreenEeeLpiHistoryIntfIndex and agentGreenEeeLpiHistoryIntfSampleIndex to see agentGreenEeeLpiHistoryIntfPercentLpiTime for each sampling interval. A port expected to be mostly idle but showing a persistently low agentGreenEeeLpiHistoryIntfPercentLpiTimeTotal might indicate a misbehaving EEE negotiation with the far-end device. agentGreenCumEnergySaving gives a running total useful for sustainability reporting, while agentGreenEeeTxWakeTime/agentGreenEeeTxIdleTime expose the configured transmit timers driving this behavior.

What Can Be Monitored

EEE mode status
per-interface low-power idle (LPI) time percentage
cumulative energy savings
EEE wake/idle timer configuration

OIDs

OID symbolic	OID numeric	Type	Access	Description
fastPathGreenEthernet	1.3.6.1.4.1.4526.10.55			The MIB definitions for NETGEAR Green Ethernet Feature.
agentGreenEthernet	1.3.6.1.4.1.4526.10.55.1
agentGreenEthernetTable	1.3.6.1.4.1.4526.10.55.1.1		not-accessible	A table providing configuration of green Ethernet features
agentGreenEthernetEntry	1.3.6.1.4.1.4526.10.55.1.1.1		not-accessible	Green Ethernet features for a port.
INT agentEthernetIntfIndex	1.3.6.1.4.1.4526.10.55.1.1.1.1	INTEGER	not-accessible	This is a unique index for an entry in the agentGreenEthernetTable. A non-zero value indicates the ifIndex for the corresponding interface entry in the ifTable. A value of zero represents global configuration, which in turn causes all interface entries to be updated for a set operation, or reflects the most recent global setting for a get operation.
INT agentGreenEnergyDetectMode	1.3.6.1.4.1.4526.10.55.1.1.1.2	INTEGER	read-write	Enable or disable Energy Detect Mode. If Energy detect Mode is not supported on a particular port then not-applicable is displayed. When user tries to set not-applicable(2) then it returns failure.
INT agentGreenEnergyDetectOperStatus	1.3.6.1.4.1.4526.10.55.1.1.1.3	INTEGER	read-only	This tells if energy detect operational status is currently active or inactive. The energy detect mode may be administratively enabled, but the operational status may be inactive.
STR agentGreenEnergyDetectOperReason	1.3.6.1.4.1.4526.10.55.1.1.1.4	DisplayString	read-only	The energy detect mode may be administratively enabled, but the operational status may be inactive. The reasons for this may be that the Port is currently operating in the fiber mode, the Link is up, or the Admin Mode is Down. If the energy-detect operational status is active, then the reason field shows up as No energy Detected
INT agentGreenEeeMode	1.3.6.1.4.1.4526.10.55.1.1.1.9	INTEGER	read-write	Enable or disable Energy Efficient Ethernet Mode. If EEE Mode is not supported on a particular port then not-applicable is displayed. When user tries to set not-applicable(2) then it returns failure.
INT agentGreenEeeTxWakeTime	1.3.6.1.4.1.4526.10.55.1.1.1.10	INTEGER	read-write	Time for which MAC / switch has to wait to go back to ACTIVE state from LPI state when it receives packet for transmission.
U32 agentGreenEeeTxIdleTime	1.3.6.1.4.1.4526.10.55.1.1.1.11	Unsigned32	read-write	Time for which condition to move to LPI state is satisfied, at the end of which MAC TX transitions to LPI state. The value of this object must be a positive integer in the range from 600 to 4294967295.
