Diagnostic Data in show interfaces transceiver (continued) Line Voltage High Warning threshold Bias High Warning threshold TX Power High Warning threshold RX Power High Warning threshold Temp Low Warning threshold Voltage Low Warning threshold Bias Low Warning threshold TX Power Low Warning threshold Power Low Warning threshold Temperature Voltage Tx Bias Current Tx Power Rx Power Data Ready state Bar Rx LOS state Description Factory-defined setting.

Value can differ between SFP and SFP+. Factory-defined setting. Value can differ between SFP and SFP+. Factory-defined setting. Value can differ between SFP and SFP+. Current temperature of the sfps.If this temperature crosses Temp High alarm/warning thresholds, then the temperature high alarm/warning flag is set to true. Current voltage of the sfps.If this voltage crosses voltage high alarm/ warning thresholds, then the voltage high alarm/warning flag is set to true. Present Tx bias current of the SFP. If this crosses bias high alarm/ warning thresholds, then the tx bias high alarm/warning flag is set to true. If it falls below the low alarm/warning thresholds, then the tx bias low alarm/warning flag is set to true. Present Tx power of the SFP. If this crosses Tx power alarm/warning thresholds, then the Tx power high alarm/warning flag is set to true. If it falls below the low alarm/warning thresholds, then the Tx power low alarm/warning flag is set to true. Present Rx power of the SFP. This value is either average Rx power or OMA.This depends upon on the Rx Power measurement type displayed above. If this crosses Rx power alarm/warning thresholds, then the Rx power high alarm/warning flag is set to true. If it falls below the low alarm/warning thresholds, then the Rx power low alarm/warning flag is set to true. This field indicates that the transceiver has achieved power up and data is ready. This is set to true if data is ready to be sent, false if data is being transmitted. This is the digital state of the Rx_LOS output pin.This is set to true if the operating status is down.
