Ihe achọrọ na Nkwadebe
Nwụnye ConfD
A na-eji ConfD (ngwaahịa sitere na Tail-f) dị ka onye na-emekọrịta ihe n'etiti Paragon Active Assurance system na NETCONF. ConfD jikọtara Paragon Active Assurance nhazi yana data arụ ọrụ na NETCONF & YANG API.
Ekwesịrị ka etinyere ConfD yana ngwanrọ Center Center, dịka akọwara na ntuziaka nwụnye.
Ịkwado na ConfD na-agba ọsọ
Iji nyochaa na ConfD na-arụ ọrụ, mee iwu ahụ
