Boshqa qurilmalar ulanishi uchun MAC-manzillar jadvalini tozalash:
switch# clear port-security [all|configured|dynamic|sticky] [address
|interface ]
switch #clear port-security all
switch #clear port-security configured switch #clear port-security dynamic switch #clear port-security sticky
Port-security sozlanishlari haqidagi ma’lumotlarni ko`rish
switch# show port-security
switch# show port-security interface fa0/3
switch# show port-security address Topshiriq
7.4-rasmda keltirilgan tarmoq topologiyasini Cisco Packet Tracer dasturida tuzish talab qilinadi;
Har bir kompyuter uchun IP manzilni sozlang va MAC manzillarni 8.2- rasmda ko`rsatilgandek aniqlang;
Kommutatorning har bir portlariga xavfsizlik ko`rsatkichlarini sozlang;
8.1-jadvalga yuqorida keltirilgan topshiriqlarni kiriting.
