Bog'liq KT Amaliyot 3-4sh vl br komandasi kommutatordagi mavjud VLANlar haqidagi maʼlumotlarni chiqaradi. Komandaning bajarilishi natijasida ekranda VLAN nomerlari (birinchi ustun), VLAN nomi (ikkinchi ustun), VLANning holati (u ishlayotdi yoki yo‘q, uchinchi ustun), bu VLANga tegishli bo‘lgan portlarning holati paydo bo‘ladi.
4-rasm. Natija - kommutatorda VLAN2 va VLAN3 tarmoqlarni sozlash
Keyin o‘xshash tarzda subnet_6 nomli VLAN 3 yaratiladi va uning ulanish portlari etib fastEthernet 0/4 va fastEthernet 0/5 interfeyslarni tayinlaymiz. Natija 4-rasmda keltirilgan.
3.1.2. Ish natijalarini tekshirish
Tarmoq sozlangn va uni testlash kerak. Agar o‘z VLAN chegaralarida kompyuterlar mumkin bo‘lsa, turli VLANlardan kompyuterlar mumkin bo‘lmasa, natija ijobiy hisoblanadi (5-rasm).
5-rasm. PC3 va PC4larga PC1dan ping
Bizda barcha beshta kompyuterlar bitta 10.0.0.0/8 tarmoqda, lekin turli virtual tarmoqlarda joylashgan.
