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 VLANga tegishli nom bilan tarmoqni funktsiyasini tezda aniqlashadi. Har bir VLAN tarmoqda qaysidir bir IP tarmoqqa tegishli bo`ladi. VLAN ni loyihalashda tarmoq adreslashining iyerarxik tizimini amalga oshirishni inobatga olish lozim. Iyerarxik 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) 7.1-rasm. VLAN 1 ga biriktirilgan portlar ro‘yxati 1 topshiriq bo`yicha laboratoriya ishini bajarish tartibi 7.2-rasmda ko`rsatilgan topologiya bo`yicha Sw1, Sw2 kommutatorlar uchun asosiy konfiguratsiyalarni sozlang. 7.2-rasm. VLAN tarmog`i asosida tuzilgan tarmoq topologiyasi 6.1-jadval
Sw1 va Sw2 kommutatorlarda VLAN (10, 20, 30) yaratish va unga mos ravishda nom berilishi (bugalteriya, student, dekanat).
