What is swSfpCurrent?
This value reports the SFP transceiver's bias current, in milliamps. Admins use it as a diagnostic health indicator, since laser bias current drifting upward over time typically signals an aging or degrading laser. A steadily rising current reading on one SFP compared to its peers could indicate that transceiver is approaching end of life.
