What is cmEthernetTrafficPortSfpTxPowerLevel?
This object reports the transmit power level of an SFP (Small Form-factor Pluggable) optical transceiver module in dBm, with an optional sign and decimal places indicating output strength. The value helps operators verify that the module is operating within acceptable power levels for reliable optical transmission. Operators monitor this to detect weak signal conditions, aging optical modules, or configuration issues that could lead to link instability.
