2-qadam. Tarmoq qurilmalarini sozlash

1. 
   PCni tanlang va Desktop bandiga kiring.
   
2. 
   IP Configuration bandini tanlang.
   

v) IP address, Subnet Mask va Default Gatewaylarni quyida berilgan jadvaldagi ma’lumotlar orqali sozlang.
g) Xar bir PC da a-b qadamlarni takrorlang.

1.1-rasm. Switch yordamida kompyuterlarni ulash.

1.2-rasm. PC0ga IP manzil berish.

1.3-rasm. PC1ga IP manzil berish.

1.4-rasm. PC2ga IP manzil berish.
d) Siz berilgan vazifalarni 100% bajargan bo`lishingiz kerak. Vazifani to`lik
bajarilganini tekshirish uchun Check Results bandini tanlab vazifani bajarilganlik darajasini aniklash mumkin.
3-qadam: Tarmoq oqimini kuzating

1. 
   Simulation rejimini tanlang, u pastki o`ng burchakda Realtime bandida
   

joylashgan bo`ladi. Band ustida to`xtatish buyrug`i mavjud.
Edit Filters bandidan faqatgina ARP va ICMPlar tanlanganiga ishonch hosil qiling.

2. 
   O`ng vertikal jixozlar bandidagi maktubni yopish orqali oddiy PDUni
   

qo`ying. PC0 ga o`ting va manbani sozlash uchun tugmachani bosing. ga o`ting va oralik masofani sozlash uchun uni tanlang. Ikkita maktub PS0ni yonida turganiga e’tibor karating. Ulardan birinchisi ICMP, ikkinchisi ARPlardir. Simulation Panel ichidagi Event List bandida qaysi maktub ICMP va qaysi maktub ARP ekanligi xaqida ma’lumot olish mumkin
Auto Capture/Playni tanlang, ARP va ICMP xabarlar almashinuvini kuzating. Quyida joylashgan Auto Capture/Play tugmalari orqali tezlikni o`zgartirish mumkin. Tugmalarni o`nga olib o`tish modellashtirishni tezlashtiradi, ko`chirish chapga bo`lsa modellashtirish sekinlashadi. Qachon bufer to`lganlik oynasi namoyon bo`lsa, modellashtirish tugagan bo`ladi. Oynani yoping, to`lgan bufer oynasining o`ng yukori burchakdagi x ni bosing.

1.5-rasm. Switch orqali paketni yuborish.

1.6-rasm. Switch orqali paketni yubroish jarayoni.
4-qadam: ARP jadvallarini ko`rish

1. 
   PC0ni tanlash orqali Desktopga kiring.
   
2. 
   Command Prompt bandini tanlang va ARP-a buyrug`ini kiriting. Jadvalda PC2 uchun MAC-adressga e’tibor bering.
   

v) ARP jadvalini PC1 va PC2 uchun tekshiring.
