VLAN (Virtual Local Area Network) yitwa "Virtual LAN" mu Gishinwa.
VLAN igabanya LAN yumubiri mubice byinshi byumvikana, kandi buri VLAN numuyoboro wogutangaza amakuru. Abashyitsi muri VLAN barashobora gukorana nubutumwa binyuze mumatumanaho gakondo ya Ethernet, mugihe niba abashyitsi muri VLAN zitandukanye bakeneye itumanaho, bigomba kugerwaho hifashishijwe ibikoresho byurusobe nkaRoutercyangwa ibice bitatuhindura.
Ibikurikira bisobanura amategeko ashingiye ku cyambu cya Vlan:
Icyambu cyo kwinjira gishobora kuba icya VLAN imwe gusa, bityo VLAN isanzwe ni VLAN aho iherereye, nta mpamvu yo gushiraho; icyambu cya Hybrid hamwe nicyambu cya Trunk birashobora kuba ibya VLAN nyinshi, shiraho rero indangamuntu ya VLAN yicyambu.
1. Kwinjira ku cyambu: yakira ubutumwa bwakiriwe nta tagi hanyuma wongere Tag isanzwe kubutumwa. Iyo ubutumwa bwakiriwe hamwe na Tag, ① yakira indangamuntu ya VLAN ni kimwe nindangamuntu isanzwe ya VLAN. Niba ubutumwa bwajugunywe iyo ID VLAN yoherejwe, Tag ikuweho.
2. Icyambu cya trunk: Iyo ubutumwa bwakiriwe nta Tagi, Iyo icyambu kimaze kongerwaho kuri VLAN isanzwe, Gupakira Tag ya VLAN isanzwe kubutumwa hanyuma ukohereza, Iyo icyambu kidahujwe na VLAN isanzwe, Hagarika ubutumwa; Iyo ubutumwa bwakiriwe butwara Tag, Iyo ID VLAN ari ID VLAN ID yemerewe binyuze kuri iki cyambu, Kwakira ubutumwa, Iyo ID VLAN itari ID VLAN yemerewe nicyo cyambu, Hagarika ubutumwa; Iyo wohereje ubutumwa, Iyo ID VLAN isa nindangamuntu ya VLAN isanzwe, ikureho Tag, Ohereza ubu butumwa mugihe ID VLAN itandukanye nindangamuntu ya VLAN isanzwe, Komeza Tag yumwimerere, Ohereza ubutumwa.
3. Icyambu cya Hybrid: Igikorwa iyo wakiriye ubutumwa ni kimwe nicyambu cya Trunk. Iyo wohereje ubutumwa, indangamuntu ya VLAN yatwaye mubutumwa ni ID VLAN yemerewe ku cyambu, kandi icyambu gishobora kugena niba ugomba gutwara Tag mugihe wohereje ubutumwa bwa VLAN (harimo na VLAN isanzwe).
Igishushanyo gikurikira nicyapa cyacu cya HDV 8ponolt:
Icyapa cyacu cya HDV 8ponoltKugena Imiterere isanzwe ya vlan mu cyambu ni: icyambu-vlan 100.
Itegeko ryo kongeramo icyambu kuri vlan ihuye ni: vlan hybrid 100 idashyizweho.Ushobora guhindura imvange kugirango igere no mumitiba, kandi idashyizweho ikimenyetso irashobora guhinduka mukirango, bitewe nibisabwa.
