swDdmVoltage
Module: DDM-MGMT-MIB
OID (symbolic): DDM-MGMT-MIB::swDdmVoltage
OID (numeric): 1.3.6.1.4.1.171.12.72.2.1.1.1.3
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: This object indicates the real time value of the supply voltage. As the value value is a floating point data type, the DisplayString type is used to define this parameter.
What is swDdmVoltage?
This read-only value reports the transceiver's real-time internal supply voltage, encoded as a DisplayString because the underlying reading is a floating-point number. An admin monitors it because a sagging supply voltage inside an SFP often indicates the module is failing or the cage's power delivery is marginal. For example, a value of "3.28" volts on a 3.3V-rated optic is within spec, while a drop to "2.9" would warrant replacing the module.
