Hey,

What does it mean when "debug hal" shows info about the transceiver?

# debug hal show optic-info ddmi port 16
Port 16
SFP or SFP+ or SFP28: SFP
Signal: present
TX Fault: no
Vendor: OEM
Part Number: ...
Serial Number: ...
Manufacture Date: 200407
SFP/SFP+/SFP28 Type: Unknown
Connector: LC
GE Compliance: UNKNOWN (0x0)
Wavelength: 1543
Options[0]: 0x00
Options[1]: 0x1a

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.)

Cheers.
