MAC manzilni biriktirish funksiyasini sozlash 
Siz port xavfsizligini sozlashingiz va yuqori kirish xavfsizligini talab 
qiladigan tarmoqlarda interfeys o’rganishi mumkin bo’lgan maksimal xavfsiz MAC

manzillarini o’rnatishingiz mumkin. Port xavfsizligi kommutatorga interfeys orqali 
o’rganilgan MAC manzillarini xavfsiz MAC manzillariga o’girish va o’rganilgan 
MAC manzillarining maksimal soniga erishilgandan so’ng yangi MAC manzillarini 
o’rganishni to’xtatish imkonini beradi. Port xavfsizligi yoqilgandan so’ng, Switch 
faqat ma’lum MAC manzillari bo’lgan qurilmalar bilan bog’lana oladi. 
Himoyalangan MAC manzillar soni chegaraga yetgandan keyin interfeys mavjud 
bo’lmagan manba MAC manziliga ega paketlarni qabul qilsa, Switch paketlarni 
ruxsatsiz foydalanuvchidan olingan deb hisoblaydi va interfeysda sozlangan 
harakatni amalga oshiradi. Bu ishonchsiz foydalanuvchilarning ushbu interfeyslarga 
kirishini oldini oladi, kommutator va tarmoq xavfsizligini oshiradi. Quyidagi jadval
