ddmStatusVoltage
Module: TPLINK-DDMSTATUS-MIB
OID (symbolic): TPLINK-DDMSTATUS-MIB::ddmStatusVoltage
OID (numeric): 1.3.6.1.4.1.11863.6.96.1.7.1.1.3
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: This object indicates the voltage of the port.
What is ddmStatusVoltage?
This read-only string reports the supply voltage measured by the SFP transceiver's DDM sensor in this port. Admins monitor it to catch a transceiver operating outside its normal voltage range, which can indicate a failing SFP or a power delivery issue on that port. A voltage reading drifting from the transceiver's rated value would prompt an admin to consider replacing that specific SFP.
