Hi All, I apologise for late response/update.

I will copy and paste switch configuration within 4 hours on another post.

Best regards,

Hi All,

I attached sflow configuration. Oddly I can't see anything on the CLI/text configuration.

Hope this helps to pin point cause of the problem.

Best regards,

Jose
