I-VLAN (i-Virtual Local Area Network) ibizwa nge-"Virtual LAN" ngesiShayina.
I-VLAN ihlukanisa i-LAN ebonakalayo ibe yi-LAN eminingi enengqondo, futhi i-VLAN ngayinye iyisizinda sokusakaza.Ababungazi ku-VLAN bangaxhumana nemilayezo ngokuxhumana kwe-Ethernet yendabuko, kuyilapho uma abasingathi be-VLAN ehlukene bedinga ukuxhumana, kufanele kufinyelelwe ngokusebenzisa izisetshenziswa zesendlalelo senethiwekhi njengeumzilanoma izingqimba ezintathushintsha.
Okulandelayo kuchaza umthetho we-Vlan osuselwe ethekwini:
Imbobo yokungena ingaba eye-VLAN eyodwa kuphela, ngakho i-VLAN yayo ezenzakalelayo yi-VLAN lapho itholakala khona, asikho isidingo sokusetha; imbobo ye-Hybrid kanye nezimbobo ze-Trunk zingaba eze-VLAN eziningi, ngakho-ke setha i-VLAN ID ezenzakalelayo yembobo.
1. Imbobo yokungena: thola umlayezo owamukelwe ngaphandle komaka bese wengeza i-Tag emisiwe emyalezweni. Uma umlayezo owamukelwe nge-Tag, ① uthola i-VLAN ID kuyefana ne-ID ye-VLAN ezenzakalelayo. Uma umlayezo ulahlwa lapho i-VLAN ID ithunyelwa, i-Tag iyasuswa.
2. Imbobo ye-Trunk: Uma umlayezo wamukelwe ngaphandle kwe-Tag, Lapho imbobo isivele yengezwe ku-VLAN emisiwe, Pakisha i-Tag ye-VLAN emisiwe yomlayezo bese uyidlulisela, Uma imbobo ingahlanganisi i-VLAN ezenzakalelayo, Lahla umlayezo; Uma umlayezo owamukelwe uphethe i-Tag, Uma i-ID ye-VLAN iyi-ID ye-VLAN evunyelwe yilesi sikhumulo, Ithola umlayezo, Uma i-ID ye-VLAN kungeyona i-ID ye-VLAN evunyelwe yileso sikhumulo, Lahla umlayezo; Uma uthumela umlayezo, Uma i-ID ye-VLAN ifana ne-ID ye-VLAN emisiwe, susa i-Tag, Thumela lo mlayezo lapho i-ID ye-VLAN ihlukile ku-ID ye-VLAN emisiwe, Ukugcina Ithegi yasekuqaleni, Thumela umlayezo.
3. Ichweba elihlanganisiwe: Ukusebenza lapho uthola umlayezo kuyafana nokwechweba le-Trunk. Lapho uthumela umlayezo, i-ID ye-VLAN ethwelwe emlayezweni iyi-ID ye-VLAN evunyelwe echwebeni, futhi imbobo ingalungisa ukuthi iphathe i-Tag uma ithumela umlayezo we-VLAN (okuhlanganisa ne-VLAN ezenzakalelayo).
Inombolo elandelayo i-HDV 8pon port epon yethuolt:
I-HDV 8pon port epon yethuoltukulungisa umyalo we-vlan ozenzakalelayo echwebeni uthi: port default-vlan 100.
Umyalo wokwengeza imbobo ku-vlan ehambisanayo uthi: i-vlan hybrid 100 untagged.Ungashintsha i-hybrid ukuze ifinyelele kanye ne-trunk, futhi okungamakiwe kungashintshwa kumakwe, kuye ngesidingo.
