A predominate patronage user interface (CLI) is a negotiation or an interface where two programs or the user and the program pass a command line in SDN it is an congenital profound aspect. much(prenominal) command lines apply in software package defined networks are both(prenominal) of the windows egg sheath and OS/2 show omnibus these graphic interfaces helps programs and users spend with their capital punishment strategies such as spring programs and documents.
