Bu yerda FastEthernet 0/2 ga statik MAC adres berilganligi tufayli MAC adresni qo’lda kiritdik:

Xulosa
Bu amaliy mashg’ulot orqali switchga ulangan qurilmalarga ishlashi va paket uzatilish amallarini cheklash va himoyalash mumkinligi, portlarga MAC adres avtomatik berish yoki o’zimiz qo’lda kiritishimiz mumkinligini, amaliyot so’ngida amallarimizdan kelib chiqib ulangan quril tarmoqning MAC adreslarini, IP adresslarini, maksimal MAC adreslar soni haqida ma’lumot olishimiz mumkinligini o’rgandik. Bundan tashqari berilgan portlarni hammasi ham ishlatilmagan holda kerak bo’lmaydigan portlarni o’chirib qo’yish mumkinligini bilib oldik.
