Hey haykel BEN SALAH ,

Hi Vivek Jagad 

I'd like to be prepared for SFOS 20.0.0 GA update but I don't know what is this after updating the DHCP interface with specific port as that was configured as "All" is about. New settings in 20.0.0 GA in Networks -> DHCP? I can't see anything remotely like that in 19.5.3 MR. Is it about port as in IP:port? What specific port to use? Or is it about specific interface? 

I'm sorry, I just don't get this. Can you please elaborate a bit more on the subject?
