Topshiriq
2.4-rasmda keltirilgan tarmoq topologiyasini Cisco Packet Tracer dasturida tuzish talab qilinadi; Har bir kompyuter uchun IP manzilni sozlang va MAC manzillarni 2.2-rasmda ko`rsatilgandek aniqlang; Kommutatorning har bir portlariga xavfsizlik ko`rsatkichlarini sozlang; 2.1-jadvalga yuqorida keltirilgan topshiriqlarni kiriting. 28 2.4-rasm.
