Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DLINK-3100-POE-MIB?

This is a D-Link proprietary MIB module for the 3100 series switches covering Power over Ethernet (PSE) port management, exposing per-port power delivery configuration and real-time electrical status. It defines tables for PSE port output voltage, current, and power draw, along with configured power limits, administrative status, and operational status, plus a main PSE (power sourcing equipment) summary table. From a hardware-monitoring perspective, this MIB is directly about power-supply health at the port level: administrators can watch for ports drawing power outside expected ranges, ports that fail to power up (operational status mismatched with admin status), or approaching the total power budget limit, which risks denying power to newly connected devices. It parallels the standard IEEE 802.3af/at POWER-ETHERNET-MIB in structure and likely maps closely to it, though implemented as a D-Link-specific extension. It is used wherever D-Link 3100 series PoE switches power endpoints such as IP phones, wireless access points, or IP cameras. Engineers can download the DLINK-3100-POE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-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.

Monitoring Examples

An administrator polling rlPethPsePortTable can check rlPethPsePortOutputVoltage, rlPethPsePortOutputCurrent, and rlPethPsePortOutputPower per rlPethPsePortIndex to confirm a connected access point is receiving power within its rated range, and compare against rlPethPsePortPowerLimit to see if the port is near its configured budget. Discrepancies between rlPethPsePortStatus (admin) and rlPethPsePortOperStatus (actual) reveal a powered device that failed classification or a port that tripped an overcurrent protection. The rlPethMainPseTable gives a chassis-wide summary useful for tracking total power budget consumption across all PoE ports.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using rlPethPsePortOutputVoltage OID:

Select a D-Link 3100 series PoE switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type rlPethPsePortOutputVoltage into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This variable indicates on the output voltage level in milli volts from rlPethPsePortIndex. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the reading drifts outside the range expected for healthy operation, since an unexpected voltage swing often points to a power-supply or wiring issue. Click Finish to create the monitor; you can adjust any parameter later.
