Wi-Fi ulanishi
5.
To'g'ri chiziqli kabel (o’rama juftlik)
Wi-Fi-dan foydalanishning asosiy usullari
1.
Wi-Fi ko'prik
- Wi-Fi orqali ikkita ulanish nuqtasini ulash.
2.
Wi-Fi router
- barcha qurilmalarni Wi-Fi orqali routerga ulang (butun
tarmoq simsiz ulangan).
3.
Wi-Fi ulanish nuqtasi
- tarmoqning bir qismini
simsiz ishlash uchun
ulangan.
Labaratoriya mashg’ulotini bajarish uchun topshiriq.
1.
Cisco Packet Tracer-da ikkinchi va uchinchi variantlardan foydalanib Wi-Fi
yaratish va sozlash.
2.
Haqiqiy uskunada ikkita ulanish nuqtasi (birinchi marta Wi-Fi foydalanish)
o'rtasida ko'prikni sozlash.
Laboratoriya mashg’ulotini bajarish.
Topshiriq №1 (variant №2)
1.
Packet Tracer ish maydonida Wi-Fi routerini yaratish (Wi-Fi router sifatida
ham tanilgan)
2.
Provayder marshrutizatorini yaratish (masalan, provayder nomi "Miry-
Mir"). Cisco 1841 routeri tanlangan.
3.
Qurilmalar bir xil turdagi (routerlar) bo'lgani uchun ularni o'zaro kross-kabel
(chiziqli) bilan bog'lab qo'yamiz. Biz quyidagilarni birlashtiramiz: Router1
ning FastEthernet 0/0 da bitta uchi, ikkinchisining simsiz Router0 da
Internet ulagichiga, chunki Router1 Internetni bizga tarqatadi.
4.
Biz Internet routerini (Router1) tarmoq bilan ishlashga moslashtiramiz. Buni
amalga oshirish uchun yo'riqnoma parametrlariga
ikki marta bosib CLI
(Command Line Interface) bo’limiga o’tamiz.
Dialog oynasiga «Would you like to enter the initial configuration dialog?
[yes/no]:» (boshlang'ich konfiguratsiya oynasiga kirishni xohlaysizmi) «no»
yozamiz.
Quyidagi ketma-ketlikdagi buyruqlarni yozamiz:
Router>en
Router#conf t
Router(config)#int fa0/0
Router(config-if)#ip address 120.120.0.1
255.255.255.0
Router(config-if)#no shut
Router(config-if)#end
Router#wr mem
Ularni ketma-ketlik bo’yicha ko’rib chiqamiz:
1)
En - enable. Kengaytiri;gan konfiguratsiyaga o’tish.
2)
Conf t – Configuration terminal. Terminal sozlamalarini ochish.
3)
int fa0/0 – interface fastEthernet0/0. Ko’rsatilgan port sozlamalariga
o’tish (bizning holatda fastEthernet0/0 ga)
4)
ip address 120.120.0.1 255.255.255.0 –IP
manzil va uning maskasini
beradi. Manzil – 120.120.0.1 (aytaylik, bu manzilni bizga provayder
bergan), maska – /24.
5)
no shut – no shutdown. Sozlangan interfeysni yoqish
6)
End – sozlashni yakunlash.
7)
wr mem – write memory. Konfiguratsiyani saqlash.
Bog’lanish o’rnatildi.
5.
Tarmoq bilan ishlash uchun simsiz routerni (Wireless Router0) sozlang.
Buni
amalga oshirish uchun, oldingi routerning holatidagi kabi,
router
parametrlariga ikki marta bosib o'ting. Yorliqlarda grafik foydalanuvchi
interfeysi (GUI - grafik foydalanuvchi interfeysi) ni tanlang.
Ushbu rejim
har qanday brauzerda routerning manziliga kirganda ko'rsatiladi.
Quyidagi sozlashlarni o'rnating:
Internet Connection Type – Static IP
Internet IP Address – 120.120.0.2
Subnet Mask – 255.255.255.0
Default Gateway – 120.120.0.1
Router IP – 192.168.0.1
Subnet Mask (Router IP) – 255.255.255.0
Start IP Address – 192.168.0.100
Maximum numbers of Users – 50
