Mavzu: Cisco Packet Tracer dasturida port xavfsizligini ta’minlash

Laboratoriya ishining bajarilishi
Ishchi sohaga Cisco 2960-24-T kommutatori, Catalyst 2960 kommutatori va Server-PT, PC-PT-0/1 qurilmalarini 1-rasmda ko’rsatilgan tartibda joylashtiramiz va ularni o’zaro kabel yordamida bog’lab olamiz.


1-rasm. Tarmoqning tuzilishi

Switchimiz portlariga ulangan qurulmalarning MAC addresslarini ko’rishimiz uchun CLI consoliga 2-rasm dagi kabi show mac address buyrug’ini kiritishimiz lozim.





2-rasm. Mac address larni ko’rish
Endi esa biz switchdagi har yoniq portga biinchi ulangan MAC addressni biriktirib qo’yishni ko’rib chiqamiz. Yani har bir portga bitta MAC ulanishi kerak.

3-rasm. Portlar xavfsizligini ta’minlash

#interface range f0/1-20 – 1 dan 20 gacha bo’lgan interface lar
#switchport port-security mac-address sticky – 1-kelgan MAC addressni o’ziga yozib qo’yadi.
#sw port-security maximum 1 – 1 ta MAC addressni 1 ta portga biriktirib qo’yish
#sw port-security violation shutdown – portdan uzub boshqa MAC address ulansa portni o’chirib qo’yish degani

CLI code ketma-ketligi
Switch>show mac address


Natija:

Xulosa
Bu labaratoriya mashg’ulotida tarmoq xavfsizligini Switch sozlanmalari misolida ko’rib chiqdik. Switch qurilmalarini sozlashda, tarmoq muhandisi qiladigan ko’nikmalarga eg bo’ldik.
