Transceiver status and DDMI

Example:

Reference model:

• Switch model name: AS5835-54X
• Edgecore SONiC version: SONiC.Edgecore-SONiC_20191003_122002_ec201904_175

Default setting:

• SFP/SFP+/SFP28 transmit power is disable (Refer to this article)
• QSFP/QSFP+/QSFP28 is high power mode.

Example: Presence of SFP transceiver

admin@sonic:~$ show interfaces transceiver presence
Port Presence
---------- -----------
Ethernet0 Present
Ethernet1 Present
Ethernet2 Not present
Ethernet3 Not present
omitted...

Example: Status of low-power mode of QSFP/QSFP+/QSFP28 transceiver

admin@sonic:~$ show interface transceiver lpmode
Port Low-power Mode
---------- ----------------
Ethernet0 Off
Ethernet1 Off
Ethernet2 Off
omitted...

Example: Information stored on the EEPROM on SFP transceiver

admin@sonic:~$ show interface transceiver eeprom
Ethernet0: SFP EEPROM detected
 Connector: LC

Optionally, you can get DDMI (Digital Diagnostics Monitoring) by specifying the -d or --dom flag. 

admin@sonic:~$ show interface transceiver eeprom -d
Ethernet0: SFP EEPROM detected
 Connector: LC
 Encoding: 64B/66B
 Extended Identifier: GBIC/SFP defined by twowire interface ID
 Extended RateSelect Compliance: Unspecified

 MonitorData:
 RXPower: Unknown
 TXBias: Unknown
 TXPower: Unknown
 Temperature: Unknown
 Vcc: Unknown

Caution: However, here is a known issue that this command with -d or --dom flag does not display DDMI of SFP transceiver properly.  It displays Unknown as above example.

Use another command sfputil instead of show interface transceiver eeprom to display DDMI of SFP transceiver.

admin@sonic:~$ sudo sfputil show eeprom -p Ethernet0 --dom
Ethernet0: SFP EEPROM detected
