Axborot texnologiyalari va kommunikatsiyalarni rivojlantirish

Ishni bajarish tartibi

1. 
   Cisco packet tracer dasturi ishga tushiriladi.
   
2. 
   Laboratoriya ishi uchun cisco 2960 kommutatori, 2911 marshruzatori, ASA0 5505 firewalli, server va kompyuterlar tanlanadi.
   
3. 
   Quyida keltirilgan topologiya quriladi.
   
4. 
   Qurilgan topologiya testlab ko`riladi.
   

Topshiriq:
Amaliy ish mavzusi bo'yicha hisobot tayyorlash. Hisobotning mazmuni:

• 
  ishning raqami va mavzusi;
  
• 
  Cisco PacketTracerda tadqiq qilinayotgan tarmoq topologiyasining tasviri;
  
• 
  tarmoqdagi IP-manzillarni taqsimlash, ulanish diagrammasi (interfeys raqamlari), shu jumladan modelning tavsifi;
  
• 
  foydalanuvchi nomlari va parollari;
  
• 
  tarmoq elementlarini sozlash ro'yxati;
  
• 
  tarmoq elementlariga kirishga urinishlar natijalari.
  

ASA0 ga quyidagi buyruqlar ketma ketligi kiritiladi.
