Vlan oppgave

Hva er Vlan?
VLAN er et akronym for Virtuelt LAN. VLAN er en teknikk for å logisk segmentere ett fysisk nettverk i flere logiske. VLAN er en ganske vanlig og grunnleggende funksjon i administrerbare svitsjer for ethernet. En fysisk switch kan bære flere adskilte nett.

dette vil si at en pc kan være på samme Internet linje som en annen pc og ikke kunne sende filer/pinge eller motsatt ved å gi tilgang på lokal nettet til en pc i oslo med en annen pc i feks Stavanger.

Hp Procuve 1700-24

Først koblet jeg HP Procurve 1700-24 til strømnettet, slik at jeg kunne starte og bruke den. Deretter koblet jeg in cat5 utp kabel til port 1 og port 2 jeg dro deretter dro jeg ut strømmen og satt den inn igjen momentant. Jeg ventet 30 sekunder, jeg gjorde dette for å nullstille switchen, siden jeg ikke viste passord eller ip adressen. Men etter nullstilling så er det ikke noe passord, bare å trykke enter og ip adressen er 192.168.2.10. jeg satte ip adressen til nettverkskortet mitt til 192.168.2.12 og koblet til.

Etter at jeg hadde logget meg inn endret jeg ip adressen til 192.168.11.10 og min datamaskins ip adresse til 192.168.11.12. deretter oppdaterte jeg swithcen

Så satte jeg opp 4 vlan: vlan 1 vlan 10 , vlan 20 og vlan 20.

Port 1 = vlan1

Port 3-9 = vlan 10

Port 10-16 vlan 20

Port 17-23 vlan 30

Port 24 er en trunk port og den frakter data fra de forskjellige vlans sammen til neste switch.
hp 1700 config

Deretter lastet jeg ned config

Hp 2524

Denne switchen var mer avansert, men etter en stund ganske lett å forstå

jeg nullstilte denne switchen ved å holde inne reset og clear til test blinket med en binders.

etter å ha nullstilt den konfigurerte jeg ip adresse slik at jeg kunne oppdatere den med tftp server

HP ProCurve Switch 2524# show ip

Internet (IP) Service

Default Gateway :

Default TTL : 64

VLAN | IP Config IP Address Subnet Mask

------------ + ---------- --------------- ---------------

DEFAULT_VLAN | DHCP/Bootp

HP ProCurve Switch 2524# vlan 1

Invalid input: vlan

HP ProCurve Switch 2524# config

HP ProCurve Switch 2524(config)# vlan 1

HP ProCurve Switch 2524(vlan-1)# ip address 192.168.11.2 255.255.0.0

HP ProCurve Switch 2524(vlan-1)# write memory

Derreter åpner du tftp 64 og velger filen din

etter dette nullstilte jeg switchens konfigurasjon ved å skrive:

enable

erase startup-config

trykk y og så rebootes swithcen

Det er vel strengt tatt ikke nødvendig

så satte jeg opp vlan på switchen.

>enable

#config

#vlan 1

#name admin

#ip address 192.168.11.11 255.255.0.0

#tagged 18-24

#exit

#vlan 10

#name elev

#tagged 19-24

#untagged 2-6

#exit

#vlan 20

#name laerer

#tagged 19-24

#untagged 7-12

#exit

#vlan 30

#name internett

#tagged 19-24

#untagged 13-18

#exit

#write memory

og så reboota jeg

etter å ha oppdatert satte jeg passord på switchen

Hp config

Cisco Catalyst 2950

først nullstilte jeg ved pressing av mode til switchen reboota stoppet og blinke

jeg valgte og oppdatere slik at jeg fikk tilgang til web styring, og ventet med å sette opp alle vlans, jeg satte ip slik at jeg ikke måtte bruke x modem som kan ta fra 5 minutter til 6 timer!

jeg var også godt kjent med tftp server ifra hp 2524

så fil

Visio:

her kan 192.168.11.99 ikke Pinge 192.168.11.88 selv om de er tilkoblet samme enhet og all data skal videreføres samme vei.

192.168.11.56 kan pinge 192.168.11.88 fordi de er på samme Vlan.

Utforinger: det vannskligste med denne oppgaven var å få starta det var en stor oppgave og jeg startet på Cisco og ble demotivert da jeg ikke fikk det til med en gang, jeg anbefaller å starte på de letteste switchene det vil også gjøre det lettere å jobbe med de vanskelige fordi du vil forstå mer.

Når jeg først jobbet fokusert synes jeg ikke det var så veldig vanskelig,men jeg slet med å finne programmare til de forskjellige switchene

Jeg prødve meg også på aoutomatisering, fikk gjort lite med powershell og ekspriminterte litt med https://sourceforge.net/projects/minimousemacro/?source=typ_redirect

ett program som logger keystrokes og muse klikk, brukte denne til å sette opp hp 2524, men det var ikke veldig effektivt, selv om jeg fikk fikset det på dene switchen så hadde den store problemer med noen oppgaver da tiden det tok for datamaskinen å gå inn på nettversk innstillinger for å endre ip var ikke konstant det var heller ikke teraterms posisjon derfor måtte jeg åpne den 6 vganger for å være sikker på at musen ville treffe riktig. det var også lagt inn pausedr etter alle operasjoner slik at tatamaskinen skulle kune henge med.
