Keng eshittirishli domenlarni kamaytiradi
1 topshiriq bo`yicha laboratoriya ishini bajarish tartibi

Xarajatlarni kamaytirish: o`tkazish qobiliyatidan samarali foydalanish va qimmat tarmoq inrastrukturalari yangilanishini arzonligi;
Samaradorlikni oshirish: tarmoqni ikkinchi pog`onada bir nechta mantiqiy guruhlarga bo`lish (keng eshittirishli domen) ortiqcha tarmoq trafigini sonini kamaytiradi va samaradorlikni oshiradi;
Keng eshittirishli domenlarni kamaytiradi: tarmoqni VLANlarga ajratish keng eshittirishli domendagi qurilmalar sonini kamaytiradi.
Аxborot texnologiyalari bo`limining samaradorligini oshirish: VLAN tarmog`i tarmoqni boshqarishni soddalashtiradi. Yangi kommutatorni ekspluatatsiyaga kiritishda ko`rsatilgan portlarda kerakli qoida va jarayonlarni amalga oshiradi. Аxborot texnologiyalari mutaxassislari VLAN ga tegishli nom bilan tarmoqni funktsiyasini tezda aniqlashadi.
Har bir VLAN tarmoqda qaysidir bir IP tarmoqqa tegishli bo`ladi. VLAN ni loyihalashda tarmoq adreslashining ierarxik tizimini amalga oshirishni inobatga olish lozim. Ierarxik adreslash degenda tarmoqni to`liq ishlashida VLAN tarmog`i yoki IP tarmoqning segmentlarini tartibli berilgan raqamlanishi tushiniladi.
Vlan tarmoqlari asosan 2 xil diapazoda bo`ladi:
1.Standart – 1 dan 1005 gacha
2.Kengaytirilgan – 1006 dan 4094 gacha
Kommutator portlari VlAN 1 ga oldindan biriktirilgan bo`ladi (default vlan, native vlan = 1)
