VTP PROTOKOLI SOZLASH
1 - qadam Ma’lumot uzatish tarmoqlarining samaradorligini oshirish va xavfsizligini ta’minlashda lokal tarmoqlarda VLAN lar tashkil etiladi. VLAN tarmog`i fizik emas, mantiqiy bog`lanishga asoslangan bo`lib, lokal tarmoqda qurilmalarni guruhlaydi. VLAN tarmog`i doirasidagi qurilmalar guruhi xuddi qurilmalar bitta o`tkazgich yordamida ulangandek bo`ladi (5.1-rasm)
5.1- rasm VLAN tarmog`i asosida tuzilgan tarmoq topologiyasi
2 - qaadam VLAN 10 ,VLAN20, VLAN 30 ga biriktirilgan portlar royxatini ko`rib olishimiz mumkin.(5.2-rasm)
5.2- rasm VLAN larga biriktirilgan portlar

3- qadam Switch 1 ni quyidagicha sozlab olishimiz mumkin(5.3-rasm)

5 .3-rasm Switch 1 sozlamalari
4 - qadam Vlanlar yaratib Switch 1 bilan bog`lab chiqamiz(5.4- rasm)
5.4- rasm Vlanlarni switch ga boglash
5- qadam Sw2 ni ham Vlanlar bilan boglab olganimizdan song Sw1 va Sw2 kommutatorlar o`rtasida trunk rejimini sozlash va magistral liniya bo`yicha aniq VLAN ID ta’yinlash.(5.5- rasm)
Sw1(config)#interface fastEthernet 0/7
Sw1(config-if)#switchport mode trunk
Sw1(config-if)#switchport trunk allowed vlan 10,20,30
Sw1(config-if)#end
S w1#show running-config
5.5- rasm Sw1 bilan Sw2 Trunk boglanish

6- qadam VLAN lar o‘rtasida marshrutizatsiyani sozlash.

Lokal tarmoqda yaratilgan VLAN lar o‘rtasida marshrutizatsiyani sozlashning 3 xil usuli mavjud:

• 
  Demonstrating the legacy inter-VLAN routing.
  
• 
  Router-on-a-Stick
  
• 
  Switch Based Inter Vlan Routing
  

Bu laboratoriya ishida VLAN lar o‘rtasida marshrutizatsiyani Router-on-a-stick (ROS) usulidan foydalanamiz.

Quyidagi komandalar orqali sozlashimiz mumkin.(5.6-rasm)

Sw1(config)#interface fastEthernet 0/8
Sw1(config-if)#switchport mode trunk

Router>enable

Router#conf t
Router(config)#interface fastEthernet 0/1
Router(config-if)#no shutdown
Router(config)#interface fastEthernet 0/1.10
Router(config-subif)#encapsulation dot1Q 10
Router(config-subif)#ip address 192.168.10.254 255.255.255.0
Router(config-subif)#exit
Router(config)#interface fastEthernet 0/1.20
Router(config-subif)#encapsulation dot1Q 20
Router(config-subif)#ip address 192.168.20.254 255.255.255.0
Router(config-subif)#exit
Router(config)#interface fastEthernet 0/1.30
Router(config-subif)#encapsulation dot1Q 30
Router(config-subif)#ip address 192.168.30.254 255.255.255.0
R outer(config-subif)#exit

7- qadam quyidagicha habar almashib natijani va o`zaro kompyuter switchlarni bir-birlari bilan aloqasini tekshirib korishimiz mumkin.(5.7-rasm)

5.7- rasm xabar almashildi

VTP (ingliz. VLAN Trunking Protocol) - lokal hisoblash tarmog`i protokoli bo`lib, tanlangan trank portda VLAN haqida axborot almashish uchun xizmat qiladi. VTP – vlan larni dinamik tarzda sinxronizatsiyalash uchun ishlatiladi;

3 xil rejimi mavjud:
1.Client – VLAN larni o`zgartirish, o`chirish, yaratish mumkin emas;
2.Transparent – bunda, switch da sinxronizatsiya amalga oshirilmaydi, switch faqat o`tkazuvchi vazifasini bajaradi;
3. Server – VLAN bilan istalgan funktsiyalarni bajarish mumkin;

5.8- rasm VTP protokolining bazaviy sozlamasi


Protokol versiyasi tanlanadi:
Switch(config)# vtp version 2
Domen va parol kiritiladi:
Switch(config)# vtp domain - domen nomi
Switch(config)# vtp password parol [hidden | secret]
Kerakli rejimga o‘tiladi:
Switch(config)# vtp mode server | client | transparent | off
Yuqoridagi buyruqlardan so‘ng VTP yoqiladi, biroq, zarur vaqtda uni ma’lum bir interfeyslarda o‘chirib qo‘yish ham mumkin:
Switch(config-if) # no vtp
