    Hello Big ,

    Greetings !!

     

    AS you mentioned this maps to interface ge-0/0/23 and if show chassis hardware output is provided i can confirm you

    Probably these logs are  issue is seen more often when non-Juniper SFPs are used, because different SFP makers handle SFP monitoring in different ways.  As long as you are not seeing a traffic impact along with the power warning, the message is safe to ignore.

     

    For more information Kindly have these below docs

    Yes this is ge-0/0/23  

    First number is fpc 

    last number is port (link)

     

    The error seems to be your partner link here is running too hot on transmit power.  Add a pad to this line once you confirm these are a matched set and appropriate power for the distance.

    Hi Big,

     

    Greetings,

     


    I have gone through all the logs and found below suspicious logs are appearing for SFP of FPC 0 –

    When a low power condition is detected on an SFP, a message similar to the following appears in the Syslog:

    The bus that the router uses to monitor the SFP and update diagnostic data is called "i2c" or IIC, for an inter-integrated circuit. Conditions sometimes arise that cause the i2c to miss updates. As a result, you might see warnings and alarms regarding low power that subsequently clear. These should not affect traffic in any way.


    This issue is seen more often when non-Juniper SFPs are used because different SFP makers handle SFP monitoring in different ways.

    Since we are receiving the low power, So I would suggest you to please re-insert or swap out the SFP at the remote end and then check if these logs are still appearing or not.

     

    Please mark "Accepted Solution" if this helps.

    Kudos are always appreciated

     

    Thanks
