Mavzu: Kommutatorni sozlash
Laboratoriya majg’ulotini maqsadi:

  1. Kommutatorning boshlang‘ich global parametrlarini sozlash.

  2. Tugun Shk larni sozlash va ularni kommutatorga ulash.

  3. Marshrutizatorlarni sozlash va uni kommutatorga ulash.

  4. VLAN tarmog‘ida kommutatorning boshqarish interfeysi IP-adresini sozlash.

  5. Portni manbaviy himoya sozlanishini bajarish.

  6. Dupleks rejimi parametrlarini va port tezligini sozlash.


Mashg’ulotini bajarilish tartibi

  1. Boshlong‘ich ma’lumotlarni olish.

  2. Mavzu bо‘yicha nazariy va umumiy ma’lumotlar bilan tanishish.

  3. Berilgan ma’lumotlarni kompyuterga kiritish.

  4. Xisob ishlarini bajarish.

  5. Tegishli xulosa chiqarish.


Kerakli jixozlar

  1. Kompyuter.

  2. Cisco Packet Tracer dasturi.


Umumiy ma’lumotlar

LHT uchun kommutatorni sozlash va boshqarish uchun bir nechta variantlari mavjud.

Bu variantlarning ba’zi birlarida kommutatorga ulanish uchun IP yoki veb-sharhlovchidan foydalaniladi, buning uchun esa IP-adres kerak bo‘ladi. Marshrutizator interfeyslaridan farqli ravishda kommutator portlari IP-adres olmaydi. IP manbasi asosida boshqarish vositasidan foydalanish yoki kommutator bilan ishlashga Telnet seansini ochish uchun kommutatorning IP-adresini sozlash kerak.

Mazkur vositalar yordamida IP-adres berilganidan so‘ng marshrutizatorga ulanish mumkin bo‘ladi. Bo‘lmagan paytda esa bevosita konsol portiga ulanishga to‘g‘ri keladi va sozlash uchun terminal emulyatoridan foydalanish kerak bo‘ladi.

IP yoki Telnet manbai asosidagi boshqarish vositalari orqali kommutator bilan ishlash uchun IP-adresni sozlash kerak bo‘ladi.

Kommutatorda oldindan VLAN 1 bitta virtual lokal tarmog‘i sozlangan bo‘ladi, uning yordamida boshqarish vositalariga ulanish mumkin bo‘ladi. VLAN 1 boshqarish interfeysi IP-adresini hosil qilish uchun global konfiguratsiya rejimiga o‘tish kerak bo‘ladi.



Switch> enable

Switch# configure terminal

So‘ng VLAN 1 interfeysini sozlash rejimiga o‘ting.



Switch(config)# interface vlan 1

Boshqarish interfeysining IP-adresi, tarmoqosti niqobi va shlyuzini sozlang. IP-adres kommutator joylashgan lokal tarmoqga tegishli bo‘lishi kerak bo‘ladi



Switch(config-if)# ip address 192.168.1.2 255.255.255.0

RouterX(config-if)#exit

Switch(config)# ip default-gateway 192.168.1.1

Switch(config)# end

Konfiguratsiyani copy running-configuration startup-configuration buyrug‘i yordamida saqlang.
