DCB Enabled On Group Configuration... But Not Anymore! Packet Errors...

Hi,

I am encountering packet errors on my arrays.  I was told by Dell Tech that I should disable DCB under the Group Configuration (DCB is not enabled when I looked under the array -> Network tab) and that should resolve the packet errors.  However after disabling DCB under Group Configuration (and saving), the packet errors count is currently going higher and higher. 

Are we looking at the right area?
