VLAN (Virtual Local Area Network) yitwa "Virtual LAN" mu Gishinwa.
VLAN igabanya LAN yumubiri muri LAN nyinshi yumvikana, kandi buri VLAN ni indangarubuga yo gutangaza. Abashyitsi muri VLAN barashobora gukorana nubutumwa binyuze mumatumanaho gakondo ya Ethernet, mugihe niba abashyitsi muri VLAN zitandukanye bakeneye itumanaho, bigomba kugerwaho binyuze mubikoresho byurusobe nka router. cyangwa ibice bitatu.
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 ID yemerewe nicyo cyambu, Hagarika ubutumwa;Iyo wohereje ubutumwa, Iyo ID VLAN ari kimwe nindangamuntu isanzwe ya VLAN, ikureho Tag, Ohereza ubu butumwa mugihe ID VLAN itandukanye nindangamuntu ya VLAN isanzwe, Komeza Tag yumwimerere, Kohereza ubutumwa.
3. Icyambu cya Hybrid: Igikorwa iyo wakiriye ubutumwa ni kimwe nicyambu cya Trunk.Iyo wohereje ubutumwa, indangamuntu ya VLAN yatwawe mubutumwa ni ID VLAN yemerewe icyambu, kandi icyambu gishobora kugena niba ugomba gutwara Tag mugihe wohereje ubutumwa bwa VLAN (harimo na VLAN isanzwe).
Igishushanyo gikurikira nicyerekezo cyacu cya HDV 8pon epon olt:
Icyambu cya HDV 8pon epon olt kugirango dushyireho itegeko rya vlan risanzwe ku cyambu ni: icyambu gisanzwe-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 kurikimenyetso, bitewe nibisabwa.
