1-qadam. Tugunni kommutatorga ulash va ularni sozlash.

a. A tugunni kommutatorning Fast Ethernet Fa0/1 portiga ulang, shuningdek B tugunni Fa0/4 portiga ulang. Yuqorida topologiya sxemasida ko‘rsatilganidek tugunlarni sozlang.

b. Mazkur bosqichda tugun B ni kommutatorga ulamang.
2-qadam. Marshrutizatorni kommutatorga ulash va marshrutizatorni sozlash.
a. Marshrutizatorni kommutatorning Fa0/3 interfeysiga ulang.
b. Marshrutizatorga CustomerRouter tugun nomini bering.
c. Marshrutizatorda konsolga kirish va parol, vty ga kirish va parol, shuningdek maxfiy parolni sozlang.
d. Yuqorida topologiya sxemasida ko‘rsatilganidek marshrutizatorning Fa0/0 interfeysini sozlang.
3-qadam. Kommutatorning boshlang‘ich sozlanishlari.
a. Kommutatorning tugun nomi sifatida Customerni bering:
Switch>enable
Switch#Config Terminal
Switch(config)#hostname CustomerSwitch
b. Imtiyozli rejimning paroli sifatida sistemni bering:
Customer(config)#enable password sistem
c. Imtiyozli rejimning paroli sifatida networkni bering:
Customer(config)#enable secret network
d. Konsol uchun parol o‘rnating:
Customer(config)#line console 0
Customer(config-line)#password console
e. Konsol porti orqali kirishda parolni so‘rashni sozlang:
Customer(config-line)#login
f. vty uchun parol o‘rnating:
R1(config-line)#line vty 0 15
Customer(config-line)#password vty
g. Kirishda vty parolini so‘rashni sozlangNastroyte zapros parolya vty pri vxode:

5 – LABORATORIYA MASHG’ULOTI

Mavzu: Kommutator uchun manbaviy xavfsizlik choralarini qo‘llash


Laboratoriya mashg’ulotining maqsadi:

1. 
   Buyruqlar satriga kirishni himoyalash uchun o'rnatishlarni sozlash oynasida parol kiritish.
   
2. 
   Xavfsizlik maqsadida server holati to‘g‘risidagi axborotni o‘chirish zarurligi haqida kommutatorni o‘rnatishni sozlash oynasida kiritish.
   
3. 
   Port xavfsizligini sozlashni amalga oshirish.
   
4. 
   Ishlatilmaydigan portlarni o‘chirish.
   
5. 
   Xavfsiz portlarga noma’lum tugunlarni ulash yo‘li bilan o‘rnatilganlikni tekshirishni amalga oshirish.
