Example:

Reference model:

  • Switch model name:All
  • Edgecore SONiC version: SONiC.Edgecore-SONiC_20201123_130028_ec202006_74

Default setting:

  • SFP/SFP+/SFP28 transmit power is disable 
  • QSFP/QSFP+/QSFP28 is high power mode.

Restriction:

  1. known issue:  This issue is fixed in SONiC.Edgecore-SONiC_20201229_070315_ec202006_101.
    "show interface transceiver presence" will duplicate on AS5835-54X 100G port.
    For example, there's only one 100 port on the AS5835-54X.

    admin@sonic:~$ show interfaces transceiver presence
    Port        Presence
    ----------  -----------
    Ethernet0   Not present
    …
    Omitted
    …
    Ethernet47  Not present
    Ethernet48  Present
    Ethernet52  Present
    Ethernet56  Present
    Ethernet60  Present
    Ethernet64  Not present
    Ethernet68  Not present

    2.Known issue:DDMI information is parsing incorrectly on 400G interface.

Example: Presence of SFP transceiver

admin@sonic:~$ show interfaces transceiver presence
Port Presence
---------- -----------
Ethernet0 Present
Ethernet4 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
Ethernet4 Off
Ethernet8 Off
omitted...

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

admin@sonic:~$ show in transceiver eeprom Ethernet4 -d

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