3-LABORATORIYA ISHI
Mavzu: Cisco Packet Tracer DASTURIDA PORT XAVFSIZLIGI (PORT SECURITY) NI
SOZLASH
Ishdan maqsad: Kommutatsiya jadvallari to`ldirilishiga yo`naltirilgan hujumlardan, tarmoqni himoya qilish imkonini beruvchi kommutatorning “port- security” funksiyasini sozlash bo`yicha amaliy ko`nikmalarga ega bo’lish.
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;
2.4-rasm. Tarmoq topologiyasi.
