Introduced : BIG-IP_v13.0.0
Sets the IP header DF bit modes for the specified TCP profiles. The DF (Don&apost Fragment) bit in the IP header of a packet indicates the IP layer implementation to not fragment the outgoing IP packets even if the packet length exceeds the MTU (Maximum Tranfer Unit) of the outgoing interface. This method allows you to set various modes that control the value of DF bit in the IP header of outgoing packets. These modes are to always set, always clear, carry over from the incoming packet&aposs DF bit value or to set the DF bit only if Path MTU is enabled.
