What is swSfpVoltage?
This value reports the SFP transceiver's supply voltage, in millivolts. It's part of the SFP's digital diagnostics that admins check to catch a transceiver drifting out of its rated voltage range, which can precede optical failures. A reading far from the expected roughly 3300 mV for a standard SFP could flag a marginal or failing transceiver.
