What does it mean when "debug hal" shows info about the transceiver?
# debug hal show optic-info ddmi port 16
SFP or SFP+ or SFP28: SFP
TX Fault: no
Part Number: ...
Serial Number: ...
Manufacture Date: 200407
SFP/SFP+/SFP28 Type: Unknown
GE Compliance: UNKNOWN (0x0)
GBIC supports DDMI. MonitorType: 68
Optic is Internally Calibrated
However "show port" acts as if there was no transceiver there:
# show ports 16 transceiver information
Port Temp TxPower RxPower TxBiasCurrent Voltage-Aux1/ Voltage-Aux2
(Celsius) (dBm) (dBm) (mA) Vcc (Volts) (Volts)
16 Transceiver is not present on this port
There is no message about DDM not being supported or any other compatibility problem in the log.
(The link is working fine.)
