I have a Temperature sensor driver error as follows:

It looks a match for CSCsw41181 - however we don't see the following condition against any interface:
'Error disabled - SFP vendor not supported'
We tried reseating an SFP on this module but still no SFP vendor not supported condition.

Any other known bugs or do we have to treat it as a hardware issue?

thanks

Hi,

If it is related to CSCsw41181, a reload of the module would clear the condition.

If you can schedule a maintenance window to reload the module, that may be the least

intrusive next step (keep in mind that reloading the module will be disruptive to all the ports

on that module).

Regards,

Ken
