Opgave 1: Opbyg netværk

Opbyg følgende netværk i Packet Tracer: (Switchene er type 2950-24)

Netværk i packet tracer
  • PC0 forbundet med lige i gennem kabel til Switch0 port 1
  • PC1 forbundet med lige i gennem kabel til Switch0 port 10
  • PC2 forbundet med lige i gennem kabel til Switch1 port 1
  • PC3 forbundet med lige i gennem kabel til Switch1 port 10
  • Switch0 port 24 forbundet med Switch1 port 24 med kryds kabel

IP adresser på PC'erne

  • PC0 har IP adressen 192.168.1.10/24
  • PC1 har IP adressen 192.168.1.11/24
  • PC2 har IP adressen 192.168.1.12/24
  • PC3 har IP adressen 192.168.1.13/24


Er det muligt at pinge mellem PC'erne??

Opgave 2: VLAN oprettes

Opret VLAN på begge switche: Husk skal gøres på begge switche..

Hvilke PC'er kan der pinges imellem

  • PC0 til PC1?
  • PC0 til PC2?
  • PC0 til PC3?
  • PC1 til PC2?
  • PC1 til PC3?
  • PC2 til PC3?

Opgave 5: Opret et VLAN mere

  • Opret VLAN 300 og kom fastethernet 0/5, 0/6 og 0/7 i VLAN 300. Gøres på begge switche
  • Tilslut PC'er til alle porte i VLAN 300 og giv dem IP adresser i det logiske net 172.16.0.0/16
  • Test det fungerer ved at pinge mellem PC'erne
