  1. VLAN Laboratorij • dr. sc. Tomaž Beriša

  2. Tema vježbe: VLANovi • Cilj: uvid u konfiguraciju stvarnih uređaja • Zadaci: postaviti i testirati razne konfiguracije VLANova i inter-VLAN routinga • Kako? ... Packet Tracer 5.0 (Cisco uređaji)

  3. Korišteni uređaji i njihova konfiguracija • Uređaji • Cisco 2950 (switch) • Cisco 3560 (layer 2/3 switch) • Cisco 1841 (router) • Konfiguracija • Obavlja se putem konzolnog priključka (“plavi kabel”)

  4. Cisco IOS • Internetwork Operating System (IOS) • operacijski sustav Cisco mrežnih uređaja • Sučelje prema IOS-u je Command Line Interface (CLI) • tekstualno sučelje (slično shellu) • Više konfiguracijskih modova, tj. razina pristupa • hijerarhijska organizacija modova

  5. Modovi Cisco mrežnog uređaja

  6. Najčešće korištene naredbe • Osnovne • enable • configure terminal (config t) • show (log/interface/ip route/running-config) • no • exit

  7. Najčešće korištene naredbe • Naprednije / konfiguracijske • interface <ime-sučelja> • nomenklatura imena sučelja: FastEthernet0/0.1, Vlan1 • ip address <adresa> <netmask> • encapsulation <dot1q/isl> <vlan> • ip • route <prefiks> <netmask> <sučelje> • switchport • access vlan <broj> • mode <trunk/access>

  8. Packet Tracer • Alat koji se koristi u Cisco Network Academy • Omogućava: • Konfiguraciju i simulaciju rada stvarnih uređaja • Postavljanje scenarija simulacija • Instaliran na računalima u laboratoriju C8-20 • Uređaje je potrebno podešavati pomoću Command Line Interface (CLI)

  9. Packet Tracer vs. stvarni uređaj

  10. Zadaci • Osnovna konfiguracija • Trunking • Layer 2/3 switch • Primjer iz prakse

  16. Zadaci - Packet Tracer

  17. Laboratorijske vježbe • Laboratorij: C8-20 • Potrebno je odraditi 6h u ovom ciklusu laboratorijskih vježbi • Gradivo ulazi u provjeru znanja iz laboratorija na kraju semestra • Laboratorij je otvorenog tipa • Potrebno je samo označiti kada ste radili na popisu u laboratoriju
